Preparing a road legal FXR150 for Bucket racing

[Ray LeCheminant]

Hi all,

We have taken the plunge and have purchased an FXR150.

So this is where are are currently at;

Completed so far
1. Remove all front fairings and lights
2. Remove speedo and mounting bracket
3. Remove kick stand
4. Remove rear lights
5. Remove pillion foot rests and grab rail
6. Wire up sump plug

We have got the tires sorted - wheels come off tomorrow for new install!

Still to complete
1. Make new header and locate new muffler below engine
2. Have a sparky dead wire it (this is something I am struggling with, what do you guys do for electric - what do you leave in....etc)
3. Locate handle bars below top triple tree
4. Preload forks by dropping top triple tree
5. Decide what seat/tail to put on it
6. Gearing setup - suggestions on pinion and rear gearing appreciated
7. Make it PRETTY....
8. GN250 carb install

Any thing I have missed guys......


Cheers

Ray

Nylon.
Str8 Jackets daily commuter has less done to it than you list and it came 9th at last years GP so don't feel you need to do silly ammounts of work to keep up.

Moving the forks up in the clamps cahnges the geometry but doesn't effect the preload.
Don't worry any way its pretty good standard, just leave it that way untill you learn to ride it.

Nylon is a must for most Kart tracks, generally an FXR will want:

Nylon bar ends.

Nylon crash bungs on front axle ends, can be attached by threading an M6 hole in the axle ends, dont make them to long or they will bend on contact.

Nylon on the muffler in the stock position or the conveniently located paddock sand kind of things on the swingarm, left and right if the muffler is inter the engine.

Nylon under the pegs, Drill 2 holes and bolt (I think I used M5) them under the pegs, cable ties aren't strong enough!

same thing with the brake lever, don't make it too long or it will scrape.

If passenger peg mounts remain you can use a couple of thicknesses of chopping board bolted into the slots to make a great bung.


More important than mad as performance mods is learning to ride well, a standard FXR can still do very well if ridden at its limits.

EDIT: Str8s bike will be raced by two people over the weekend and still be ridden to work on tuesday.

Awesome, thanks Koba....yes the Nylon is a MUST - forgot about that....:doh:

AS you state, my son needs to learn to ride it most importantly, I guess the list is more of a "game plan" moving ahead.....

Just more quality time with the garage floor ahead I guess...

Wiring is probably my biggest worry....there are relays and abcle looms for Africa!!! :shit:

Don't worry about it unless it's broken, spend the time moving the exhaust because that will make much more of a difference.

Been reading a bit, and there seems to be mixed view on the header pipe size....

[thealmightytaco]

Not that I've made it to the track yet, but for my 2c on the muffler, I got something like that 2nd one but it was for a 2 stroke. That one you've linked to has the right pipe diameter but the chunk on the end looks a bit heavy I thought, so I went for this one:
http://www.trademe.co.nz/Trade-Me-Motors/Motorbikes/Parts-for-sale/Exhaust/auction-280579867.htm
Except I got a black one, didn't scroll them all to find that one. This one is super light (4~500mm of header pipe I left weighs more than the muffler), and the little flange you can bore out and weld directly to the header pipe, easy as, but the problem with this one is the pipe diameter is about 4mm smaller than it should be, working out to 25% drop in cross sectional area. I'm not sure how that affects things yet as I havent made it to the track, shortened length and fact that it's straight through might balance it out, but if it turns out you need to, I'm pretty sure it aint hard to repack it with a larger bore.

And on the wiring loom, mine consists of only the coil, cdi, rectifier, fusebox.... um, bound to be something I've forgotten... oh, the magneto signals etc, and then I've also got, kill switch (tether fashioned from 3.5mm mono jack plug, don't know if this is kosher but it works), and a couple bits I'm not sure are needed like the key ignition and the old capacitor-instead-of-battery fix. But I got tricky trying to make it road legal still so kept those in, and then I made a second loom with all the headlight and indicator relays, speedo, dash, fuel gauge, etc, and a 6 pin plug then connects the 2 looms, my streetfighter bucket then ready for the street. Took a bit of figuring but it was a momentous occasion when I got it to work, I've never been a sparky.

Have a look at www.fxr150.co.nz for the wiring diagram anyway, and a couple peoples modfied takes on it, is the only way to begin to understand the thing.

Both of those are average, the froza opne will be too loud, just ask cougar. And the crf250x one is two heavy and big.
Look out for a crf25or one, ask around, or a can made for a crf150r.....they fit perfect.

Those wiring diagrams are mine, really you dont need to touch the wireing just tie it all up and put it out of the way, dont waste your money on a sparky, its not that hard. If you ever want to do anything wit it just ask and I am sure someone will be more than happy to help for a box of piss, and you will learn somthing as well.

Dont convert it to total loss, you are just creating more work for yourself.

If you are on a budget and have access to the gear hacking up the standard one is great value for money.

the only thign total loss is good for is, it means you can remove the heavy fly-wheel magent and starter gears...which will boost up your horse power...i did it to mine, makes it rev like nothign else, hard to keep the front down!!

Couple of dozen woodstock sounds great! not that i can help much, but ill still take the woody's :p

Seriously though, i'm quite keen on help with various things too (wiring, fork setup, exhaust hacking etc) so im happy to provide boxes of whatever for help

[woodyracer]

I can help with fork set-up, ive got a tool to take out the oil witohut sliding the forks out of the tripple clamp, and ive done it a few times on bikes,Also i can help with exhaust's ive just build my cbr125 one.

Thanks Max - might take you up on the forks once we have it up and running/

Doing some strange stuff - batter went dead for some reason today.

Would not kick over with kick start for a while, then it did - worn gear or something

Jump started it from the car - ran it for a while but battery still dead.....

Inverted and changed handlebars - easier than I thought.....want to do away with choke, but will wait until I get the GN250 carb on it....

Missed out on a paddock stand on TM tonight (PISSED OFF) , I want that so I can put it on up on stands and take wheels off....getting their slowly! :Punk:

Yeah GN250 carb is cheap and easy, literally took me 5 minutes. didnt even need to adjust the throttle cable.

[Damien_Toman]

Hi Ray
All I have done with my FXR is add an XR400 carb (probably a bit big - it bogs at low revs) and slick tyres on the standard wheels (with tubes). I also added CRF250R dirt-bike handlebars (required new throttle cable and brake line) after bending the FXR bars. The rest is totally standard. I still have the speedo, electric start and standard exhaust. My biggest problem is the exhaust as it scrapes on the track even after moving to the inside of the mount and adding spacers. So, you don't need to do much to go racing. The most important change was the tryes. My exhaust has to go! I have a dirt-bike pipe ready to cut but I need a downpipe. Anyone any suggestions on a downpipe?
Regards
Damien

[Scotty595]

Havent tried the top speed test yet. Although it could only haul my fat ass to 120 with the standard carb on so shouldnt be too hard to beat. (cant really check atm as speedo not working)

I have seen that exhaust scraping lol! Infact i have seen quite a few exhausts scraping, hence why i want to get mine moved.

From what i have heard the standard FXR pipeis pretty much spot on, just good to get it shortened and exhaust mounted under the engine.

the only thign total loss is good for is, it means you can remove the heavy fly-wheel magent and starter gears...which will boost up your horse power...i did it to mine, makes it rev like nothign else, hard to keep the front down!!
So removing weight from your flywheel etc will boost up the horsepower yeah? Probably 2 or 3 hp yeah?

so where does that come from? It's been a while since I did physics at skool. please explain.

[thealmightytaco]

So removing weight from your flywheel etc will boost up the horsepower yeah? Probably 2 or 3 hp yeah?

so where does that come from? It's been a while since I did physics at skool. please explain.

Rotational inertia, and the fact you're throwing weight away.

[F5 Dave]

ooh a bite..

So the act of the throwing is Kinetic energy by accelerating the parts toward the bin. I have done work lobbing these bits into the skip. . . . Not sure how that makes the bike faster. The starter gears largely aren't turning more than a small idler gear until clutched in & I can't see much loss of hp in that. So this rotational inertia thing creates the hp does it? How much HP would we expect?

[woodyracer]

it boosts the revs up, as the engine dosnt have haevy weights on it.

Got a carrot up your ass or somthing.......geez

[saxet]

What Dave is trying to say is removing the flywheel cannot increase power, seriously how can it? It has no effect on the engines state of tune.
What it does do is remove some of the mass the engine has to accelerate, letting it spin up faster. It also tends to remove the engines torque effect and reduce engine braking.

[Kendog]

So the act of the throwing is Kinetic energy by accelerating the parts toward the bin. I have done work lobbing these bits into the skip. . . . Not sure how that makes the bike faster.
Some FXR's were throwing bits off their bikes during the racing in the weekend, not sure we got a pre and post measure of HP or lap times to validate performance improvements.

[F5 Dave]

Arse sans carrot. Check.

So first it boosted up the horsepower, now it boosts up the revs? So now it will rev higher? is that good? Just engage brain before keyfingers when giving 'advice'. What you mean, as Tex pointed out (although for torque effect I would have said flywheel effect to avoid confusion), is it will accelerate the lighter rotating objects faster. That is not an approximation of either of your statements.

Well that was what i was told by the mechanic that did it......,And you coulnd notice a huge difference in power.....
I am engaging my brain.....but your just ingaging your attitude........Sorry to distract you from your butt-scratching exercises.

[thealmightytaco]

The flywheel's attendance or lack of has no effect on horsepower created by the engine, but the fact that precious horsepower is no longer needed to get a heavy wheel spinning (energy sapped by rotational inertia) means there is more available to instead rotate the wheel and propel your arse sans carrot forward.

Rotational inertia doesn't decrease or increase power, but it will steal some, thereby decreasing it at the wheel perse'. Parry dodge spin.

oh, i though you loose torque not horse power.

[thealmightytaco]

oh, i though you loose torque not horse power.

Get both probably, horsepower is essentially rate at which torque is produced (power = work over time), and with the flywheel no longer absorbing precious torque to wind it up, there's more torque, and over several thousand revs, there's more power.

[saxet]

I should've said flywheel effect at low revs where a road bike can stall at manouvering speeds. If you're moving at almost an idle, in particular, a wheighty flywheel gives inertia to the engine to decrease the chances of stalling. Once the flywheel is lightened the engine has less mass to spin up when you accelerate it.
Once the engine has accelerated it makes no difference to the engines outright power.
I would be curious to see what it does to the torque curve on a dyno, I suspect it could be similar to gearing an engine down.
E.g. it allows the bike to accelerate faster but does'nt give it more outright power.

Yes true, once the flywheel has inertia it doesn't need to steal any more to get moving, so it would affect the curve more than peak anything.

I should stop pretending to be an expert on this, I just remember the basic principles of inertia etc from Uni. I also remember the flywheel exists to smooth out the revolutions to as you say prevent stalling, and also to smooth out the otherwise even more jarring accel and decel on the conrod and piston etc, therby preventing fatigue and ultimate failure. I think, might have to check that. But in other words, I'm pretty sure to take it out would cause more winning, but also more expenditure I believe.

[thealmightytaco]

Double post.

While I'm here though, just remembered higher revs may have been the thing that reduced forces on conrod, not flywheel at all. As piston and rod race back and forth faster and faster at higher revs, the force of the gas pressure on the piston is reduced thanks to the fact the piston is racing away from it, rather than hanging about and getting squashed. At some point the conrod obviously can't handle the direction change though and it fails anyway, but higher revs do reduce fatigue of conrods.

Hmmm, amazing what sticks in your head sometimes.

[F5 Dave]

Once you have got the flywheel spinning you have converted it into potential energy so the energy hasn't been lost. Of course the same can be said about the wheels, tyres, valve stems clutch & whatnot.

I'm not saying that lightening the flywheel is not a good thing, just there is no free lunch & certainly no free hp.

Erm practically that theory on fatigue sounds very shaky. If your tutor was trying to be clever I think he was under-thinking the effect on a dynamic engine.

So the argument is that the gas pressure is what causes the damage & having the same pressure alone for shorter time at high revs is better than having it there longer but many less times is counter intuitive, but the fact that higher revs causes the combustion chamber to be smaller as the rod is stretching/bearing clearances being used up would increase gas pressure. That is why you have squish clearance, also there is the tuned range that will increase pressure at certain frequencies as well. But plain old lubrication, bearing acceleration, Youngs modulus of the material & so on will kill the rod as the revs go up pretty effectively.

Thing about Tutors & other academics is that they are always trying to prove that they are smarter than the next person. What they should really do is research their opinions on the internet where the real experts are.:blink:

A good mod for some rally engines was to put a flywheel from a Van on it. E.g. 4k Starlet engine with a 5k van flywheel.

In that application the stored energy being available to stop the engine bogging under sudden loadings can be more valuable than a quick spinup.

I guess it's question of matching the mas to the application.

Anyway...

Gas squish is but one of several factors, and not necessarily damaging but up till the danger end of the revs is one of the more dominant forces present. And indeed in an engine that revs higher may well have tighter clearance and more gas pressure than a larger pistoned lower rev engine, but they'd both do well to be driven nearer the top end of the revs (if only considering conrod life, ring life would be another story, hence all this is just an interesting aside that I remembered yesterday after confusing it with the flywheel effect). An engine will only rev as high as it has been designed for though, very shortly above that the force of having to change the direction of the piston becomes the immeasurably over-riding factor, the conrod then tearing in two or some such equally devastating operation.

She actually had graphs of the strain on the conrod for a particular engine (mitsi something?) revving at different speeds, it forming a convoluted oval with a big bottom hoop on it for low revs, the whole thing tightening into a little circle a the revs got higher. She didn't have the graph with the thing ready to snap but it's pretty well documented in shards of metal all over the world I believe.

Once you have got the flywheel spinning you have converted it into potential energy so the energy hasn't been lost. Of course the same can be said about the wheels, tyres, valve stems clutch & whatnot.

I'm not saying that lightening the flywheel is not a good thing, just there is no free lunch & certainly no free hp.

Indeed it hasn't been lost, but it's been stored in a wheel rather than being used by you to go forwards faster.

[F5 Dave]

can i use that quote ?
it's a good one
Not a bady huh? knock yerself out.

[F5 Dave]

A good mod for some rally engines was to put a flywheel from a Van on it. E.g. 4k Starlet engine with a 5k van flywheel.

In that application the stored energy being available to stop the engine bogging under sudden loadings can be more valuable than a quick spinup.

I guess it's question of matching the mas to the application.

Anyway...:stupid:. . . . . . . . .


Yes road engine is about making it idle nicely but You can go too far in some cases. But at least we are starting to talk in terms of aceleration of revs rather than some change in power. The only way that occurs is if there is loss through friction where it is turned into kinetic energy:heat. Balancer shafts can fall into this category as they aren't symmetrical so they can cause some drag, but often that is irrelevant.

[F5 Dave]

Getting Hot;

I am puzzled. ignore the fact that I fitted GN250 carb today, because this problem has been with me since Sun after I had pulled the non-essential wiring out.

With the bike idling, and the occasional blip, the pipe is getting VERY VERY hot, and the casings are rather warm. Is this normal?

Is there anything I could have done during de-wire that would have affected anything, could the CDI affect this?

Might sound like I am a dumb arse , but it's got me screwed!

[Henk]

The casings will get warm and the header will get seriously hot. Nothing to worry about. Playing around with four stroke dirtbikes in a garage at night the headers can glow cherry red.

Na thats pretty normal to me, the pipes get hot as they are double wall steal and hold heat and theirs lots of trapped gases inside. Remember the engines get hot as they are air cooled, I could be wrong, but it seems all normal to me, Good luck with the rest of the bike.

So am I right, there is nothing electrical that can advance/retard the bike.....??

[Henk]

Look at it his way. About 3 cm from the top of the header you have the combustion chamber. It gets pretty hot in there.

Yea the exhaust gases sit around in there and slowly leak out.....also the very very thick steel they use dosnt help, Maybe one day ill use my powers for good and teach suzuki how to build exhausts :yes:.

You fella's should see the exhaust i made for my cbr, not one to brag....but you'll all be green with envy.....:sick:

Oh yea, and ray dont buy a racing CDI if you wana say :bye: to your engine. Look forward to seeing your motofxr on the track soon.

Your header pipe is 2 icnhes thicker ?

Is it made from 80mm cored solid or some nice 3 icnh pipe ?

Seat arrived - fitting is a little fun - nice fit straight out of the box though....:shit:

Will have to make little hoop mounts to keep it off the battery (orig location) and make the rear height adjustable

[Henk]

Mock up the location with bits of wood etc and try the position before you start drilling holes. You may want to move it backwards or forwards as well as up and down before you start drilling holes.

Looks pretty by the way ahaahaha

[Ray LeCheminant]

I have made some 19mm tubular hoops that run from left to right, 1 @ 50mm back from the tank mount, and the other is 10 mm in front of the old rear seat lock. The is keeps the seat off of the battery too.

Each mount has two 8 x 1.5mm threaded lugs welded into the tube with the idea being that spacers (rubber) can create height options

THe seat is pretty strong, so should not flex too much on the mounts

Slowly getting there....pipe arrives tomorrow....pod filter arrived today.....

[F5 Dave]

He said "Mock up" not "use" Wood is a wonder material, you can drill it screw it glue it &saw it quickly. Most of my rearsets etc go through a pre-production phase of ply (after a design stage of card or plastic) before morphing into ally. Good enough to mount footpegs to test riding position before cutting expensive stuff.

Why are the glass tail pieces so popular ?

[Henk]

Because they are reasonably light and crash well.

[saxet]

Why are the glass tail pieces so popular ?

I like em cause you can lower the seat height and move it forward or back if you want.

cause they look trick..........to be honest my the stock seats are nicers to sit around on...

Yoshimura Trick Exhaust

OK you yoshimura fans - your mission is to identify the following muffler - not that I need to know really, but I do need to understand the mounting bracket, design.

AS you will see in the photos , the input side has a main input, surrounded by 6 x M6 holes

WTF? - how do you mount this sucker.....there must be some sort of bolt on flange?

Anyone seen this before?

Arghhhhhhhh

ok....basicaly yes its flange welded to the pipe, your probualy going to face difficulty mounting it, as you need to make a flange then get it all to line up. Your better of getting a slip-on exhaust system. Im abit of a yoshimura fan, that exhaust isnt actauly a yoshimura, Tim fraser has the same can {or similar} and its a chinese replica...fooled me the first time too.

Getting a flange welded up is easy, the centers are evenly spaced, so just a case of ensuring I use a decent gasket....lining up is no different that a slip on Max, as once the flange is on the muffler , I'm gonna slip it on!

"fooled me the first time too" - could not resist - Max, that would not be too hard :shit: :yes: :sick: :innocent:

There is a whole bunch of different ways you could mount that sucker, most involve a tig and or a lathe though..

P.s I'm making a chromoly seat sub frame for the stock seat. It's too damned comfy to not use..

[F5 Dave]

Yeah when you read TSR on the side you think wow that will be expensive, but then you look at the mounting side & think - That weren't made in Japan, some one's taking the mick.

They used to run a 250 in GPs in late 90s that did well.

Looking good.

So what is the colour going to be?

I am also thinking about colour choices..... seems there are going to be a few FXR's that look simular... can't wait to get mine going...

After seeing Damian's motor issuies I thing I will strip the motor and make sure it all OK!

[Ray LeCheminant]

Matt Black it is then :)

Deep Candy Apple Orange - white lines, and carbon fibre and black trim - gonna look hot....

We have bought our bike preparation sponsor through from minimoto, and the young guy that does all the graphics work is awesome .......

Yeah, I am a little worried about Damien's issue too...but I am wondering if he gave it the big rev when we came off meeting before last...we are putting a tel-tac on ours, so I can at least see what the young fullah has been doing out there....

Are you guys running different CDI's?
One of the reasons I don't think I will swap from the stock CDI is the rev limiter.

[Buddha#81]

Thats the one thing that will stay standard on mine.....in heat of battle the rev limiter is in use constantly!

Same.
I have found it interesting watching my race videos. I can hear the rev limiter at certain points on the track, so i think next time I need to change up earlier or maybe change gearing.

[Damien_Toman]

I have the standard CDI unit with rev limiter intact. I hadn't thought about the bike being stuck on full throttle after a fall - hmmm. The Tel-tac sounds interesting. I noticed Gavin V had some sort of computer on his FXR at the last Mt Welly meeting - looked very interesting though I didn't get a chance to chat with him about it.

[Buckets4Me]

Same.

I let mine rev till the frame starts to sing (vibrate realy bad) when the corner is to close to bother changing gear

thats the good thing about not having valves or valve springs
the power drops way off before the rod or piston seem to get to stressed (about 14000 rpm is the most I have ever seen ,normaly around 11500 to 12000 rpm)

!/4 Turn Throttle Solution:

http://www.trademe.co.nz/Trade-Me-Motors/Motorbikes/Parts-for-sale/Performance/auction-289045426.htm

FItted to FXR150 with either the standard carb, or as we have done the GN250 carb.......fantastic....just watch Connor get launched backwards when he moves the throttle 1.5mm on the startline.... :shit:

After farking about with various throttle bodies, asking various bike shops about a solution, only to be told about 35mm, 44mm, 65mm cable travel, and would I like that to be 65 degrees or more.....I gave up and ripped the throttle off of one of our trusty Minimoto machines....wallah!!!!...but it don't come with the Domini logo or the $150+ price tag either

$25.00

http://www.trademe.co.nz/Trade-Me-Motors/Motorbikes/Parts-for-sale/Performance/auction-289045426.htm

Ready for this weekend?

Thanks for the info on the throttle.

[Ray LeCheminant]

Not completely ready......still trying to fine tune a few things, end goal is July , Round 1

Having some issues with GN250 carb fitting....but will get that sorted - currently throwing a nice 8 inch flame on the over run - rather spectacular....onboard tire warmers

Panels, will not be ready until next week - no rush

[Ray LeCheminant]

GN250 Carb Issue

1. Excuse DUMB :yes: question - carb has what appears to be 2 inlets , left and right - which one is fuel feed, which one is overflow

2. Jetting - any suggestions on GN250 carb

3. Manifold - do guys that run the GN250 on the FXR use the existing rubber manifold, a mallet and some super glue....or is it supposed to just fit , cause mine is TIGHT :shutup:

Other than that ....it will start (under duress) but gets bored and shuts down, hence the question about FUEL LINE and JETTING

:o)

Ray

P.S But the blue flame rocks!!!! :soon:

[Kendog]

Hey Ray,
The left side of the carb is the fuel inlet, should be same side as your fuel tap.
I have had some issues with the GN carb in the FXR manifold (falling out of the manifold, manifold splitting). I have since cut a couple of mm off the carb face that slides into the manifold, this means it should slide in far enough to allow the rubber lip to fit into the groove in the carb. As a back up I have used a couple of heavy duty cable ties round the carb and engine to ensure it no longer 'pops' off.
I have luckily not had to deal with jetting, as it was done before I got the bike. This link may help http://justkdx.dirtrider.net/printcarbtuning.html

[Henk]

I just jammed the GN carb into the existing manifold and yes it is tight. Jetting I've left at the standard GN specs and this seems to work after a bit of fiddling with the air screw.
The two GN carbs we have are a little different, the older one on my bike is a Mikuni and the newer one off an 05 GN on Michelles bike is some knock off still japanesse but not sure of he brand. They both seem to work about the same.

[Ray LeCheminant]

Headstock Bearings (Cup and Cone)

Pulled the forks off tonight, the cone case seems to be made of a plastic of some description....is this right?

How do you tell if they need replacing, they seem to be stiff, and covers in a very thick plasticy grease.

Also, when putting it back together, how TIGHT does the top nut need to be , nipped, or torqued up?

Cheers

Ray

[Henk]

Do it up until it's tight and then back it off a little until it turns freely.
If you want to be scientific the manual states 45 Nm meters, turn the bars a few times to bed things in and then back off 1/4 to 1/2 a turn.

[Pumba]

If you mean the bit that the rollers sit in Ray then yes that is normal that it is a heavy duty plastic.

And as henk said you should tourqe it up, but I have never had an appropriate socket so have used the same method as Henk

[Ray LeCheminant]

No fancy torque wrench available...so hand tightened.....seems ok....

Stripped down for powder coating....black chassis looks mean.....pics soon of finished bike - FINALLY - what a mission.....

I suspect you have the wrong Connor

possibly I was wondering why he had to consolt with John about the colour of the bike

[Ray LeCheminant]

All ready to go finally - panels coming back this week

Really pleased with the result. Thanks to all those that have assisted and provided advice and suggestions , Henk and Pumba deserve special mention...

Will need to do some jetting adjustments on the day, so would appreciate any "help" that is on offering. I don;t have any number drills, so I might get some 100's this week, as I suspect the GN250 is about a 135.

IF I am going to carry some spares, what am I getting, just main jets?

Idles ok, but needs choking, or hand half over inlet to get it warmed up....ideas?

Here are some pics of the bike after we had the chassis powder coated.... $120.00 if anyone is interested.....takes about 3 days

[TZ350]

.

Congrats, another great looking bike..............the FXR guys are sure lifting the bar for bike prep.

Just a tip, you might want to invest in new footpeg brackets before you take the bike out..they break on first crash

Bike is looking good anyhow

Airport Engineering Services charged me $65.00 to cut two from 12mm alloy. They are in Aintree Avenue , off Rennie Drive in Mangere

[Henk]

Damn that's looking good. Looks like I'll have to repaint mine at some stage to avoid getting made to park the bike out of sight in the pits.
I have a spare set of footpeg hangers in the van that can be loaned out on the grounds that they either come back at the end of the day or if we smash one on one of our bikes. Same goes for standard clip ons.
Still planning to get some hangers drawn and water cut but seem to have no time to get started at the moment.

Oops forgot. Michelles bike with a GN carb on GN jetting is as cold blooded as hell. Needs choke to start and runs like a dog down low until it warms up. I wouldn't start swapping brass until you've run it a few laps.

Yeah, we noticed it's a pig until cold...good thing about the GN250 carb is the choke proximity...easy to get to. If you give it too much handle when it's cold it blows a nice flame...gets around the tire warmer issue :shit:

Will give it a fews runs as you say on the Saturday and "bed it in" - make sure all the bolts are nice and tight for the lad :yes:

I have put up a website with various photos etc of the build, it's bloody scary how much you can spend on these if you get carried away

[Henk]

Anything costs when you start getting serious about it, I started to add up what bikes had cost us as a hobby once, soon stopped, way too scary.

[Arronduke]

got to agree on that.... one good thing is I have cleaned out alll my bike parts paying for my FXR build....

still quite a long way to go...

Do it yourself with a jigsaw.

[Ray LeCheminant]

They fit up just like the original, you have to create 2 placement holes, either side of the bolt for the peg, to accommodate the pins in the pedal....but works ok.....

[Buckets4Me]

Just one of them.....

if you can lend me an old one or do a drawing I could make some up in my spare time at work

they look easy to do
and the cutter we have could do that no sweat
the drill press will do the reast
all I would strugle with is finding the ally (I might just have to buy some :) )

All finished !!! :Punk:

One last project to complete - gear light indicator LED's on dash - figured out how to do it tonight, just need to pop down to Dick Smiths and get some LED's - BIG GREEN one , so he don;t bloody stall it!!!!

Oh - seat rubber on - got some spare if someone wants the left overs...enough to to do 2 more bikes

[Henk]

Looking good.
Did you leave the electric start on? If so the big neutral light won't be quite so critical, pretty sure Michelle's fired up on the button in gear with the clutch in after I crashed it last month.
Looks like only numbers and nylon to go. Looking forward to seeing it in the flesh next week.

[jasonu]

That is the flashest looking bucket I have ever seen! nice job mate.
What does it weigh???

[Yow Ling]

Looks like a really professional job, bikes like yours are good for the image of Bucket Racing. Well done !

[woodyracer]

starting to looks like briggie's RC8, looking good, cant wait to see it down at mt welly on the weekend.

[Muzzab]

I think the bar has just been raised. No way I'm ever going to be able to compete with that in the pretty stakes.

Id agree with that, well done that man

Stephen

[Arronduke]

yep hat is off... and I'm standing on it....

[Arronduke]

One thing I have noticed is there does not seem to be much crash protection?

Are you going to add nylon ?

[Ray LeCheminant]

Yeah, just figuring out where to put it

Looking forward to Sat to see how it goes, and having some fun.....

[Kendog]

That looks awesome!!

[F5 Dave]

That is outstanding! I've been racing over 20 years & I've never seen a bucket look like that.

You do of course know what happens next outing?

[Ray LeCheminant]

LOL - yep, as Connor say's "&^%D happens, it's gonna happen" , it does , it will....and it will get fixed with a paint brush...LOL

Goal 1: Have fun - and he is so looking forward to his test run on Saturday...

[F5 Dave]

Good attitude.

I used a spraycan & masked off the good area with a towel (its the preparation that counts).

[woodyracer]

dont worry ray, i just took the paint off my shinny new gt250 on the weeekdnd! now its a race bike!

I put door stops on my one where the farings bolt to the frame...although i dont think i ever crashed on my fxr so i dont know how good it would of worked.

[Arronduke]

This is what I have planned.

<a href="http://s982.photobucket.com/albums/ae304/Dukeman2/?action=view&current=280f_12.jpg" target="_blank"><img src="http://i982.photobucket.com/albums/ae304/Dukeman2/280f_12.jpg" border="0" alt="Photobucket"></a>

8mm thread so will screw in to the FXR swingarm... made of plastic :shifty:.... and landed for $15NZ.... sounds good to me... could not make them for that.

For the frame Im looking at these.... (where your faring mounts)
<a href="http://s982.photobucket.com/albums/ae304/Dukeman2/?action=view&current=BmEPoTwmkKGrHqYOKjEtlrRN4LBLeNsfUIF.jpg" target="_blank"><img src="http://i982.photobucket.com/albums/ae304/Dukeman2/BmEPoTwmkKGrHqYOKjEtlrRN4LBLeNsfUIF.jpg" border="0" alt="Photobucket"></a>


Slighty more expensive at $50 landed... does not seem so good... how much to buy plastic and have it machined?:confused: OK $50 its a good price considering $50/hr to machine them plus plastic...

[Arronduke]

another good thought... but it means a hole in your fairings... where your fairing mounts on to the frame above the motor... ... (henk told me this) drill through the frame so a 8mm threaded rod goes right through the box section..from left to right.... have a look at my build on FXR site and you will see what I mean.. then screw somthing like this on.... good protection and looks OK... and most importantly its strong.

<a href="http://s982.photobucket.com/albums/ae304/Dukeman2/?action=view&current=DSC04005Small.jpg" target="_blank"><img src="http://i982.photobucket.com/albums/ae304/Dukeman2/DSC04005Small.jpg" border="0" alt="Photobucket"></a>

Then some small bits of nylon or simular on the foot pegs... and lastley some thing to protect the front axle... (this is from Colin... orange CB125) replacing my front axle with a longer one with and putting a simular protection to the frame plastic on either side of the bolt head and nut... again nice and strong.

Thats looks like a might fine idea.....do the swing arm ones double up as bobbins?.....would love a set if you wanna bring in 2

Make a hole through the fairing is no stress.....

[Arronduke]

do the swing arm ones double up as bobbins?.....would love a set if you wanna bring in 2

Yep...
just waiting for some measurements...

No problem will be at Mt Wellingtin Saturday.. I hope...deoends on brother in law... hoping he will have a go.

I will bring in a set for you no problem... let me know if you want the faring ones also?

[Arronduke]

I have not ordered any yet just priced them up... will order soon...

All good...."he's not going to go fat enough this weekend to need them" :yes:

[grantman]

Awesome looking bucket
Makes mine look sad and lonely

Bucket might not be the right name anymore for some of these tidy racing machines

That a good idea.. There's holes in the spada chassis around that location already.. And I can just pinch some nylon from work.. Sorted. And threaded rod hahaha.

[Scotty595]

[Henk]

You mean the FXR isn't finished yet?

[Scotty595]

You mean the FXR isn't finished yet?

Mine? Nah I haven't been able to do anything yet! hopefully i will get it done withing the next few months :\

[Ray LeCheminant]

69 is ready to roll....ran it up the driveway last night - sweet....takes a whgile to warm up on the GN250 carb, 1st 1/4 of throttle very hesitant until it's warm

See you guys tomorrow...

IT"S NOT GOING TO RAIN!!!!!

[Buckets4Me]

whateva happened to the road lega part of this FXR

[Ray LeCheminant]

whateva happened to the road lega part of this FXR

Explain, I'm lost - it's not road legal any more.....LOL

Do you need some road legal bits.....??

[F5 Dave]

Are you taking the piss? from the start we all thought you were trying to keep it road legal. hence the title.

[gatch]

Taking a road legal bike and preparing it for the track, perhaps ?

[F5 Dave]

Well all buckets start as road legal, but 15 mins strips off any of that kack.

[Ray LeCheminant]

Well all buckets start as road legal, but 15 mins strips off any of that kack.

I think it was about 15min - LOL

Yeah, maybe the title was confusing...but I did take a road legal FXR and made it no longer a road legal FXR ....

I guess the dumb thing about it is that since we bought it, the price of FXR's has gone up, (opportunists) so I should have put more effort in being to bolt the parts back on....

Could have sold it is "neither raced, rallied, or rolled"....well , not rallied anyway

[gatch]

Well all buckets start as road legal, but 15 mins strips off any of that kack.

Haven't seen any as purdy as this one though..

[Buckets4Me]

Explain, I'm lost - it's not road legal any more.....LOL

was just rereading the title lol

I think it's worth more now than when it was road legal

[Ray LeCheminant]

It's not for purdy now....but only superficial thank god!....

Awesome day guys, thanks again to Henk and Michelle for the loan of the wets......Carl, hope you mend well.....Damian seemed to be hobbling ok.....Connor is nursing a fat lip and sore legs.....the bike is stripped and panels ready for the PAINT BRUSH....

You gotta laugh....but all is good!!!

Thanks guys for a great (ish) day!!!

Binned already huh ? Drats.

[Henk]

Shame about the bin and resulting damage to both bike and rider, he was going really well before then. Don't think he'll be in the B grade for long somehow.

I got tempted to head out when it started drying, but then all the crashes happened, and it just put me off. I was glad a) Connor was okay b) he didn't crash on my wets, cause I knew it'd then be MY fault loll
Carl, let us know how Scott is too, he was in a lot of pain.

[Ray LeCheminant]

Binned already huh ? Drats.

Yep Gatch - it's binned - LOL - we'll now we got that out the way , no more worries about he paintwork....but was a fun day.

[Ray LeCheminant]

Shame about the bin and resulting damage to both bike and rider, he was going really well before then. Don't think he'll be in the B grade for long somehow.

Plenty of time for "A" grade - LOL - he got off lightly (body wise) and I got off lightly (repairs wise) compared to poor old Damien, not sure why his chain went so tight, but there were a few bent bits....and for the carb bowl drain screw to come out...that puzzelled me.

Anyone head how Nick (?) is - broken collar bone?

[Henk]

Scott indeed has a broken collar bone, was looking decidedly uncomfortable when he left to get doctored at. Pumbas ankle aint great and Damiens knee is feeling second hand. Add Connor to that and the list of walking wounded looks pretty grim for the time frame it all went wrong in. Rick was also parking an ice pack on his finger at some stage, not bad enough to stop him going out in the next race though.

[Damien_Toman]

The bike looks awesome - this is it before it tasted the tarmac.211047 Photo by my big bro' Ray.

Damage is ok...gravel rash is easy to repaint...

God I love your F2.8 - starting to sound like a scratched record.

Hope the bike and you mend well mate - that motor of yours was humming !!!!!

[Damien_Toman]

That was the 400mm f5.6L. The f2.8 400mm is a bit expensive! I'm limping and sore but nothing major. The bike needs quite a bit of work. Yes, it was running well with the new bits - shame I blew it and took Pumba down as well :(.

[Arronduke]

There will be a few repaires over the coming month... most of the crashes happened once the track dried out... everyone was so thrilled it was dry that they gave it heaps.

What happened to Connor? I took off from the start and next lap I saw him on the side of the track... on a stright? Was he hit from behind?

I enjoyed the day with a 4th and a 2nd... not bad for a CG on road tyres ... (the truth being that there was only like 5 people in the last race)

He's not completely sure, I think he got his nose wiped.....he's sore, neck, shoulder, legs....bike is not too bad either....biggest issue is the front end...went unnoticed until late last night....working on it...

Yeah...rain, wets - caution....dry , slicks....mayhem - there was a noticeable change - lol

I was beside him at the start
Didn’t see or feel anything (would have defiantly known if we had collided)
I expected him to pass me on the first lap, as he had done in the first prelim race.

Then I came around for the first lap and was shocked to see him on the side of the track.


Maybe Damien or someone else might have some photo’s to help piece it together.

[Damien_Toman]

I was being nursed and Ray was checking up on me at times so unfortunately no photos of the incident.

Thanks mate!!

[Arronduke]

Cool video.... Ray... about the sprocket setup...

12 front and 49 rear?

sound right?

49 rear is standard buy the looks as thats what I have.

thanks

[Arronduke]

Looks like Connor got hit some how.... I did a bit of a wheelie of the start which cost ... felt huge on the day... wife had a good laugh.

[grantman]

I Watched the youtube HD version a few times and you can see what happens
Glad it wasnt me who took him down

Bummer though ..hope bike & Body heals well

Arron's wheelie is funny .......Dangly legs flailing everywhere !

[Arronduke]

Yea the CG is very good off the mark... good low down grunt...

Wonder how the launch control will go on the FXR... we forgot to try the new CDI on your bike in the weekend.

Typical the only video off me on a start and its a small wheelie and legs...

I will do much better when Connor and Grant are in the A grade on their FXR's... leaving the B grade to old crappers.... oh and Graham.. heeee

[Ray LeCheminant]

Front end fixed - woo hoo ....undo lower triple tree bracket - TWANG....straight again...amazing!!!
