Preparing a road legal FXR150 for Bucket racing

[Buckets4Me]

Connor is now now negotiating color schemes with me.....LOL - negotiation is an interesting word!

!

depends on wich side of the gun you are

[Ray LeCheminant]

I'm on the pen side of the cheque book - is that the same thing?

Matt Black it is then

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!

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.

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.

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:

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....

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

looks great... whens the body work turning up?
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 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

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

)

Ray

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

[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
