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....

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!!!

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

Sweet - any ideas on a muffler

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

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-Mo...-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.

Original wiring diagram halfway down this page:
http://www.fxr150.co.nz/discussion/v...3&t=7&start=10

Modified racing one with a dash still included halfway down this page:
http://www.fxr150.co.nz/discussion/v...&t=64&start=10
Dash isn't a necessity to run but the rest of this diagram is.

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

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.
