I'm building one

[Drew]

I'm building a bike, just for the sheer fuck of it, and having a bike I can afford to run.

For the most part it will be a zero budget, and whatever bits I can scrounge from mates, so look the fuck out anyone in my way, there's a good chance whoever gives me the brakes for it is having a laugh!

Peace out.

[koba]

There is a shitter on trademe that I think is Nicks old bike for a hundie bucks...

[koba]

Ah, a hundie bucks buy now, less for bid...

[Drew]

Ah, a hundie bucks buy now, less for bid...

Never mind, I found it.

You just want to have fun in the Bucket section of the Kiwibiker :)

Fuck yeah bro, I am just dying to argue about rules with these guys!

[Henk]

Fuck yeah bro, I am just dying to argue about rules with these guys!

In that case you will end up spending less that a hundy on your bike, by the time you get it all straight we'll have run out of oil.

Flag drops bullshit stops ....If you need to bend the rules it meen you carn't ride quick enough...You will love buckets ! Top blokes top fun ..

Look cunty, I might be able to find you some wooden clogs to scrape on the ground.


Maybe I could find you a caliper off an old Morris. . . .but it would have to operate directly on the rim,

now now dont be silly

I have some rope and an old ship anchor

he can save some money and forget about a helmet

[F5 Dave]

ahh, I have a few bits. . . If he gets something together that will actually go.

I'm sure we have the odd spare floating around as well if it helps get him going
but I dont hold any hope for a bucket being built with such a big budget :innocent:

but on anther note... where the hell is your bucket Sinfull..????.. or you in the same group as Choppa... all talk and not show????

I came up with the motor I wanted to build if I had money, but will keep it close to my chest I think.

Prolly gonna go with a 125 pit bike motor since I have a spare sittin in the shed. There's power to be extracted with a three valve head and a compression bump.

Frame will be an MVX250 roller, with quite a bit of angle grinder modification.

I have a Large 2 valve head. I wouldn't mind swapping for a std 110 head?
I am guessing you don't currently have a 3 valve Head?
Well even if you do the HP won't be as great as you may think it will.

With regards to the brakes.
Don't use for the than the scrutineer deems necessary. As brakes only serve to slow you down buckets are all about corner speed you down anyway.


If you really are desperate enough to go the pitbike route here are some useful links.

It would be great so see a $100 bucket build but it may not be that competitive but getting out there is most of the fun and there is little snobbery inside buckets

There are some interesting mods that have be carried out to other horizontal singles in this case CT110 same guy too.

unless you are a master fabricator.

That's cool, but I have admitted to myself now that without spending money the pitty aint gonna have the poke, and those crate motors are not legal since they are a competition engine.

What sluts me off most is that I have given away heaps of engines that would be perfect for a bucket in the past, now I'm left without one for my self.

I really want to go cb125T to be honest, but they are gettin hard to find.

BRYCE!, Where you at an what ya got sitting in the shed mate?

The ones I have posted above in the last link are not crate Motors?
It is a CT110 with a XL125 and Xr200 head and the same guys later creation with a FZR600 head sectioned into a cylinder.
But you are still left with a 4 speed of dubious strength.
I would go with a Suzuki single or a Honda single if it is still a tight budget build.
If not go with a newer twin if your hearts set on a twin the 250 fours and the 400/4 are cheap as to, bought in blown form. I have brought 2 FZR250 3ln motors for less than $50 one with carbs. Speedpro has done one for a project.

[Drew]

I have brought 2 FZR250 3ln motors for less than $50. Speedpro has done one for a project.I am wondering why that FZR motor has the two right hand slugs instead of the middle two. It'll fire as a cross plane now, and there's no advantage to that in a twin the I can think of.

Bloody good idea though, and there is an FZR250 in the garage that I can steal the motor from if someone distracts Jimmy for a couple hours.

The idea was, Well my interpretation on what Mikes idea was,He did it that way so he didn't have to seal up the other side of the motor. As well he was trying to do it without a having to do a total engine fabrication.

The one I started (But never beyond concept stage) was on a VTR250 crankcase it was going to be the same basic layout and so nearly fits across the lower cylinder.
The firing order on the FZR means the outer 2 are 180 degree cranks the inner two. May be able to made to suit the CB125t in layout but they (The CB125t) are a 180 degree and the inner two on a fzr250 are essentially a 360 crank.But then again the cb125t is a built up crank isn't it.

Off course you could always just chop a cylinder from a VTR250 engine finding a donor should be easy. Stay clear of the VT250F though they were made of Chocolate.
Better ports though. bore it out to 66mm ish or stroke the crank use the other rod as a balancer.

The original Vf400f with cam chains could be de-stroked with a metal sprayed crank 55mmx32.5mm =155cc as it will be shagged by now and the rear or front heads removed.

But the simplest solution as always is a FXR150 as much as it pains me to say it.

[F5 Dave]

Mike told us how much had been sunk into that FZR engine. Everything costs money, it isn't a hacksaw job.

Scrape together $500 & wave it under Bryce's nose & seen what he can find is probably the easiest & most likely to bring fruit of something workable in a reasonable timeframe.

[Brian d marge]

Ahhh building bikes for nothing , welcome to my world !!!

It will cost some money, but you would be surprised what you can do with a bit of resourcefulness...

Cant tell you the current bike , as its top secret , and I would have to eliminate any potential leaks , but its a VMX Cr250 I did the frame, and Suspension internals , for less than I would spend at the pub

The one up on the bench next, is an Enfield chop, rigid using a SU carb AHAHAHAHA :banana:, Ive set my self a budget 100k yen and a time limit , the custom chop show next year in Nagoya ( April )

I love this kind of a challenge, and its amazing how cheap you can get a class looking bike together .... last year I bought a complete TX650 Yamaha for I think 500 dollars , in NZ ( gave it to my old man as a thank you )

What got me all fired up was an article in an UK bike mag about these two northerners , who having no money , would buy an old bike and spending as little ( and I mean little ) they would restore these old bikes and ride them to big events such as the IOM.

Finally I must say the one good thing about living here in Japan , is they don't have this sort of culture , ( is changing though) but you can still find real bargains ,

right lets go and see if that paint is dry !!

Sorry Dave as this is a Kiwibiker bucket build thread so therefore.
In the classic tradition of a bucket build thread I didn't actually expect him to build it.:weird:

But here is something that does run has extra stuff to flog off It is DOHC 4 valve 125cc 5 speed and is $900 on the road. Don't laugh it could work with a new frame and a bore out.
http://www.trademe.co.nz/motors/motorbikes/motorbikes/scooters/auction-421226844.htm

it looks like it can be uprated to FXR150 piston at least i will check out the valve sizes in TKRJ

It may end up cheaper as I don't imagine too many people would want to pay $900 for that. I may be wrong though.

Want a ZZR600D/400K front caliper and master? I have some spares here you're welcome to, I have a spare rear caliper, it's a queer twin piston one, but has a pinched seal.

Might have some other bits of shit floating around too.Cheers mate, but would mean replacing the front end with something normal. The MVX roller has Honda's questionable inboard disk thingy.

I do appreciate all the looking for bargains you guys are doing, but I think some of you are missing the point a bit. I have no money, now in most people's vocab that means they could only scrape together a couple hundy for a motor, in mine it means I am skint.

I will be doing my fine lady's bidding for anything that needs purchased.

However, I'm a very ingenious when it comes to fixing broken things. So if you've got a broken motor, or know someone who does I could really do with that.

[F5 Dave]

fair call, I couldn't rub 5hundy together atm without owing it elsewhere& having an infraction.

only drama with the MVX is the 16"er. I think a lot of crap was written about inboard discs over the years by people too stupid to know how to take the wheel off.

I have ZZR fork lowers and internals that are usable, so if you can find some 41mm legs for cheap/free, the fork lowers/brakes are yours.
It's easy enough to steal shit....
I have a set of four CVK-D32 (I think, will look tomorrow) you can have if you need a carb, or four.
I even have a spare ZXR400L fork stanchion. :yes:
I'm in the same boat for cash at the moment.

Sport Demons are my tyre of choice on this thing unless I change the front end, which might be a possibility.

[F5 Dave]

The first attempt to get one off is usually enought o put anyone off trying again. . . ..
Yeah I remember back in the day making the mistake of taking my CBX550 in to a prominent wgtn centrely located motorcycle shop get a new tyre away back in the day & returning to "oh it will be another 1/2 hr" as the poor apprentice hammer bearer was a bit short of smarts & it was taking him a while.

From memory it was three 10mm head bolts take the cover off either side (550s had twin disc, 400s single), bungy it out of the way, remove the callipers/torque arm bolt, screw driver twist to take the disc off, axle out - job jobbed. Haven't done one for 20 years but got pretty good at it as I never took the bike into a shop again after the above mentioned cretin didn't tighten the torque bolt & it dropped out while I was riding the next day.

[husaberg]

I donate something to the cause.
Once you sort out what sort of engine you are going to run.
I have some XL125s and xr200 stuff if you go Honda.
As long as it gets a cool porn star name. ie your first pet and the street you grew up on.

[ducatilover]

Had a peek in the garage today, if you go with a 17 inch front I have two useable tyres, an IRC RX01 (horrible piles of shit, but it's free) and a Shink Advance 005, it's in pretty good nick but it's a 120/60.

a not completed bucket motor project.

XL 185 motor with a xl125 crank in it to destroke it to fit inside the bucket F4 regulatiions

I built this from scratch and the new components are, mains, big end, rod, 0.25 piston, cam chain, cam chain tensioner and guide. valves have been lapped and head ported.

Have not installed the clutch but it is sitting in the box along with a pile of new gasket sets.

Pick up only please

Feel free to ask questions .

Turns out it is a clymer hot up but i will post it anyway it is old but a start. The MX100 has a 26mm carb vs the DT100 22mm
The thing with Yamaha's is better parts from the hotter models can be fitted, but more so for the 125cc bikes.

[Drew]

The price for the hundy was right, and although it will be slightly down on power it'll be better than the 125 pit bike motor by far.

Reed valves will definitely help, and a wee raise in the port timing and compression are very cheap ways to extract some more.

MVX expansion chamber might be a touch small, but it'll have to do. I think I'll use the high pipe so as not to limit ground clearance, which is probably the biggest hurdle to overcome when getting them to corner.

Crasher has offered to clean up the exhaust port too which is awesome! I'm not really giong for big power but more a useable motor, I really just want to know that it'll start every time and run smoothly.

[F5 Dave]

Just been looking at YZ100 pistons on ebay that would likely fit. 100 means you can run big carb, 28-32 should be fine.

[Drew]

Very sensible.

Now where is the real Drew :innocent::lol:

I've never been about what bike I'm on mate, I more enjoy riding whatever I'm on WAAAAY past it's, and my own, limits.

I wonder if I could make it reverse ported by turning the barrel around, it'd certainly make the pipe easier to build!

[F5 Dave]

people have done that with old RDs, but usually the answer is no, bolts preclude that & the boost port/inlet area can get complex, but maybe not so bad on a DT hmm , yeah Yams usually have a plain floor. then you don't want the carb picking up the front tyre's cast offs.

[Drew]

I don't plan on leaving the carb mouth completely exposed, but I suppose it'd be a mongrel in the wet.

Righto, lets work on the theory that the good people at Yamaha knew what they were doing when they aborted the reverse port TZR. Yet, the TZ was a screaming success and they had backward shit going on.

[Drew]

I just did a little searching, and sure enough, I can spin the head and barrel round and it'll bolt straight on.

So just for the fuck of it, I'm gonna run it that way so I can say I have a reverse port Yamaha that goes!

[F5 Dave]

well you turn the inlet which is a big gaping hole on a yam into the thrust face. not an issue on a full case engine like the TZ or TZR.

Either way you are doing quite a bit of engineering to avoid cutting & rotating a pipe about 7 times to make a header.

Oh yeah, hadn't thought about that. Just looked to see if it'd bolt on and figured it'd work.

I'd concentrate on a pipe and carb to start with.

The gains from putting a bigger carb on my MB engine were phenomenal. It did take Dave threatening to poo in it to get me motivated but it was well worth it. I'm sure we will have an internetless chinwag about it sometime soon.

Hahaha I wondered when Drew said it was a DT100 if Yow Ling had saved himself some freight :laugh:

If so Drew, the motor has already been ported and had a brand new Wiseco piston in it. It has no doubt been sitting for quite some time, so might pay to strip and replace main bearings etc. It had a 28mm flat slide on it when i had it.

While MX100A transmission details might be interesting wouldnt a MX transmission be illegal? :no:

WHY?

http://motorcycle-specs.com/motorcycle_specification.asp?manufacturer=Yamaha&model=MX100&year=1979

The Yz80 and yz100 was the comp bike if the MX100 is a MX bike Yamaha wasn't really trying that hard. THey couldn't even be bothered to remove the autolube?
Yes I think it had no lights but so does the crf50

[Yow Ling]

WHY?

http://motorcycle-specs.com/motorcycle_specification.asp?manufacturer=Yamaha&model=MX100&year=1979

Because with that gearing it would be so fast when it passed other buckets the air would be sucked out of the other riders lungs causing him to black out, simple really !

[gav]

WHY?

http://motorcycle-specs.com/motorcycle_specification.asp?manufacturer=Yamaha&model=MX100&year=1979

Because the MX range was the prerunner to the YZ range.

We could Argue but who cares. The MNZ doesn't.
Unless you put one it. Drew hasn't got a MX trans as far as i know.

Shit, that could work well in your favour.

Get the bike running and then look closer at the motor once you can actually take it out on the track. That way you won't end up with something that looks great on paper but is useless on track.

I'll wait 'till you are ready before the box of Heineken goes on the line.

Running it without replacing or even checking the bearings for rust will probably end up as an "I told ya so" moment...

That's the one mate, tyre stack right on the apex of turn 4 to stop the cars cutting the corner.

[Drew]

I have that 32 but it probably won't fit whatever carb rubber is on your motor. + it's likely to be a bit too big to start with.

Bryce has one he reckons, so I should be doing test track laps this weekend.

Does anyone know if a two stroke can be made less obnoxiously loud without hindering the performance? I fuckin hate the sound of singles, two or four stroke. Might be getting into the wrong class on that basis, but needs must an' all that.

[F5 Dave]

yeah an effective muffler just needs some volume, some thought & some support. if left unsupported for ages it will vibrate crack. perforated tube & some direction changes are good things.

I made a 2ndry muffler when a track was getting hard on noise that I could bolt on. It was another section with a reversal & some more perf tube slightly larger di than primary. Didn't make any diff on the dyno. Sadly it couldn't be supported so I made another with just a reversal end cap for the rest of the time so it doesn't break all the time. And when I say 'I'. I mean I gave it to Damon.

20mm tube should be about right for your 100. Don't want to start too big as that is giving noise away to start with. Too small isn't good for piston crown temp though. Within 30-40cm you can fit a reversal & heaps of perf tube. A reversal can just be 2 bend bits of pipe welded to each other so they miss, ie outside walls a couple of cm. use ally tube, steel 'rings'. Some like that silent wool packing, but I find Daytona mat is better.

[Drew]

Cheers for that Dave. If they standard cans off the MVX weren't so bloody heavy I'd split the pipe in two off the expansion chamber and run two of 'em.

[F5 Dave]

You still want to have a stinger effect from a hole equal to about 20mm & 200 long. maybe could make the same with two real small pipes, but not sure of the formula.

Depending where the pipe ends up the cleanest way to mount the muffler may end up being under the tail piece or under the bike. Mike's MB has the stinger do a 180 & the muffler mounted under the engine with a 180 facing the outlet back again. Not much issue as it's only gas bleed at this point of the pipe. Sketchy has done the same thing.

In fact there is more potential benefit from making the diffuser cone closed and taking the stinger off the pipe at the widest point. The amplitude is lower so it is quieter & again it doesn't seem to care where the bleed of the gas is taken off. I first saw this idea in a dirt bike magazine over 20 years ago, erm closer to 30. The Kawi 100 I had use of for a while used this system. Makes the muffler crashproof & you have heaps of room there from the looks.

Two pipes off the centre with thin mufflers would be real quiet, again not sure what dia, whether plain area calculation would be enough to get you close, couldn't say.

I don't understand your mounts from the grainy pics.

[koba]

Cheers for that Dave. If they standard cans off the MVX weren't so bloody heavy I'd split the pipe in two off the expansion chamber and run two of 'em.

I cut an RGV one down so it didn't weigh so much.

My bike is quiet as using the method Dave describes above. When the muffler fell off it was still one of the quieter bikes on the track.

[husaberg]

A quick note on mufflers

Taking note of what Wob had said when repacing my sons KTM muffler for the nationals last weekend.
I repacked he muffler as tight as i could.

It was packed as tight as possible (Basically wound on) it may indeed have been more powerful as Wob had said it would be.
But I had to repack it looser as i was getting quite a few comments on the line from the officials that i should consider it time to repack the muffler as it was rather loud.
Once I repacked looser that night it was indeed quieter but was possibly slower?

[quallman1234]

I have a standard TF125 muffler, you can have if your stuck for one. It will be restricted as hell, but very quiet.

I have posted this elsewhere But as everyone is lazy
As a tip for others the best easy source of thin wall like 1.2mm or something.
Its irrigation tube mainly used one market gardens now not real farms ask around if your have rural mates but cheap as by the meter at Mico's comes in 75 and 100mm

I used to just buy the fibreglass packing wool string not cloth at the car muffler shop
$10-15 will do all the mufflers you are likely to ever use in a lifetime of racing. About 1 kg

As Drew is on an limited budget go to dump rip open oven and find high temp fibreglass matting hiding inside

If you want to get real trick for a 4 stroke the rotary guys use stainless steel turnings from a machine shop. They last forever even with a pp20b.
For the baffle I just used to spend a few minutes with the drill and a bit of exhaust tubing. Make up a couple of ends one circle with a hole on it the inside. The other a flat bit of sheet about 25mm wide and 250mm to 330mm long weld at right angles. Bend around the circular disk end as you go. Secure with rivets hold it on with springs to the stinger. Away you go.

Either that or get a couple of Speights cans, some Pinkbats and a cold chisel. Drink beer first before assembling muffler..

I'll piss around with it a bit for sure, but doubt there will be any major changes in the the way it's put together.

As a point of interest.
The kart guys used o have a goop.
Made to apply to older tires to rejuvanate them.
It was made in NZ, cheap and smelled like wintergreen.
It couldn't do any harm.
I will have a look to see what it was called.

It was also illegal for a few classes, it was used on control tyres to make them "softer" than they should be

Yup thats the shit, was amazing on the kart tyres, apparently a few teams were using it in Moto2...

Those naughty boys. they were using the control tyres though just spilling some solvent on them so its err I guess ...... a Grey area until the no doubt ruled against it. which I guess no doubt they did.

I had a look in the shed the label is a bit hard to read but the stuff i have is called SL200 traction treatment for Kart Slicks.

It has no manufacturer so I think it was indeed home brewed in NZ. It still smells of Wintergreen too.
I seem to think i recall a mate saying he knew the guy that used to make it. I will ask him who it was and if he still does it if not he might say what was in it.
I just thought it might help Drew as i guess his tyres are hard to get in a sticky compounds now being I suppose 16 and 18 inch.

My understanding talking to the Kart guys is that tyre "doping" is now illegal in all classes. No doubt you can still get it though

[koba]

I had a chat to one guy who said it got to the point where some Kart racers were doping a set of tyres, wrapping them in glad wrap and leaving them in the hot water cupboard for up to a year before an important event!

[F5 Dave]

yeah but it gets the tyres sticky & ok for a race, think you may be able to redo it, but the oil would disappear pretty quickly & make the tyre harder. OK if you've got a big tyre budget, but not the point here.

I used to dope my tyres before every meeting, the tyres were amazing it felt like you were driving on hot tyres straight out of the pits. It gives live to old tyres. I actually tried to find some recently but the kart shops got upset that I was asking

[Drew]

Sport demons will be sticky enough for now. There are also some Bridgestone tyres available in my sizes that are supposedly better and cheap.

Drew and I found that a good road ride will scrub the crust off an old slick.

Followed by a dumping of oil on it from the starter motor hole !!

Oh fun times.

Yep got some (tire dope) from Lascom motorsport. That was before it was made completely illegal. It was great but you needed to use it between races. Apparently it had a really hi Kero content and some other shit. An acetate of some sort. So just paint them with kero and your cooking. Gave up on that and just got better rubber after crashing my brain out on substandard shithouse road junk.

[Drew]

I put a better expansion pipe on today, and messed around with the ignition. The pipe is an improvement I'm sure, but the ignition was a backwards step. It'll fire up and rev better...for about 10 seconds then shut down and chuff a couple times as it winds down. Might have the points gap too small, but I'd have thought that would be a constant misfiring issue, rather than running good for a bit then shutting down.

Only time I've encountered the same thing was on an IT200 with a bung spark plug. So I'll chuck in another before I go back to fucking with the points. Which I set at .06mm incase you're wondering...and incase my maths was wrong in converting .014in into metric. Should be .055mm but I don't have a feeler gauge in that size.

The thing is louder now, nothing on a 125GP bike, but it's a sound that will always great me so I'm not that barred up about it. Someone wanna swap a four stroke with me? I'll get the smoker tuned and running awesome for ya first.

Is it crash protected? No metal parts should be able to touch the ground in a crash.
Just checking as I haven't seen you mention it yet.

Don't waste your breath. It will never fly.

[Henk]

From what I've read about Drew it's more likely to crash than ever be finished. In this case I suspect nylon track protection is more important than a running engine.

[Yow Ling]

Come on its 2011, pictures please !

What carb did you end up using on it?

Don't waste your breath. It will never fly.Fuckin nae sayers. Mine will be finished, and soon. Then I will build a better one, as my daughter will be 13 next year and she can race the original.


From what I've read about Drew it's more likely to crash than ever be finished. In this case I suspect nylon track protection is more important than a running engine.When I'm upright, I'm fast though.


Come on its 2011, pictures please !It looks the same as the pics I've put up already, but with a different coloured pipe.


What carb did you end up using on it?26mm round slide at this point. I'm big on simplicity, and going too big creates a situation where everything else needs to be within a closer tolerance. As I have zero stroker tuning experience, I'll forego a couple % power in favour of consistency and reliability.

Nah broo. We can certainly do that, but I was thinking of something more like a support group for depleted old men getting whipped in public by their daughters. I certainly expected Tylah to have the Mair gene.

. . .

0.055?! was that a typo? that is no gap at all.

btw google will do all your conversions if you ask it. 0.36mm for .014"

[blackdog]

Just put a micrometer on a hair from my beard, got a touch over 0.01. I think you're probably right that a points gap should be more than 5 hairs breadth.

[Madness]

25.4(mm = 1") X 0.014 = 0.3556 (0.36mm as Dave said). It's not rocket science.

[jasonu]

Might have the points gap too small,

.

Hey Grandad, what are points and this gap you speak of???

[Clivoris]

Hey Grandad, what are points and this gap you speak of???

They're in the cupboard next to the record player.

[husaberg]

Hey Grandad, what are points and this gap you speak of???

The manual says as you were corrected to.
14 thou or .35mm it also says not to bother to adjust if it is 12-16 thou or .3-.4mm

Didn't the old buggers used to use rollie papers or something. Do they even sell points files now.

out of interest if you decide to ditch the flywheel and go to total loss remember to modify the cam for better results.
Also gift the flywheel to Te Papa, The kids would get a kick from seeing ignition systems pre CDI.

[Drew]

Ok, that's good news. I did think I ended up with a decimal point in the wrong place, but must have been totally fuckin off with how I worked it out. Will set the points again, and then I can fiddle with the jetting.

I can't be arsed removing the fly wheel, charging batteries is something I'm likely to forget a lot.

[F5 Dave]

yeah total loss is a drag & I've seen a lot of CB125 bucketeers ruin their meetings with a failing battery.

[koba]

I was really tempted by the superflash competition batteries they have at TSS.
The thing must weigh about 200g.

They use them in MX and stuff, even to crank over a starter with a total loss system! :shit:

Still, I know it will go the same way... " Fuck, I'm sure I charged it..."

[Moooools]

We just bought 3 batteries so we always have a spare should we suspect one is faulty.
$30 each and 300g. Charge in 1 hour.

[F5 Dave]

then tie a barking dog to your gear bag to remind you to take them off the charger & throw then in the van.

[Drew]

Progress update.

Got the points gap right today, and it ran heaps better. Opened up the muffler on the pipe, and played with jetting.

Got it running best so far by a long way, but when onboard and loaded up, just where you'd expect it to come on real strong, it peters out.

Had to jet it down way too far considering the pipe and carb that's on it, to achieve the level that it's at. So this is kinda indicative that it's still not sparking cleanly at higher revs.

Next thing is gonna be a new condenser on the ignition circuit to eliminate the only thing that could still be wrong in said circuit. I'm also dubious of the reed block, the stoppers that make the reeds progressive were all different shapes when I got it, and although I straightened them to a more uniform curve, who knows how closely they resemble what they looked like from the factory.

From there if it still aint right, it's a sheet of 1mm steel plate, a book, a welder, and a whole lot of time building an expansion chamber that is tuned for the flow and combustion chamber of this engine.

[Drew]

Turns out that the DT100 that was kindly let go to me....ummm, has some issue. ie, the piston seems to have collected the head. This has done surprisingly little damage to the head or the piston....But I don't think gudgeon bearings should be so tight the piston doesn't just fall one way or the other, and I could swear that the conrod never used to have an 'S' bend in it.

So, I am selling a pair of my much loved racetechs tomorrow, which will allow me to buy a motor.

I'm kinda slutted with myself for not having realised this earlier. I've spent fucken HOURS trying to tune out a horrible dead spot in the middle of the rev range, which as it turns out is probably just where everything comes together in just the wrong way.

BUGGER!

If you know of a motor that's legal, lemme know please.

Picked up the donor bike today, with a bonus box of engine bits. Tomorrow to mount the power plant in it's new home, and later in the week to whip it out and assemble in working order.

I have 25mm internal and 32mm internal pvc and a bending spring for 25.
Plus I also have some preformed corners in sharp and soft bends plus conduit glue.
I also have 25.4mm steel internal tube 1.6mm wall Drew.
