Anyone use a CRF 40mm carb on the trx??

If so what was all needed to make it work? as far as cable,hot start and tps....also what was used to extend the inlet out to reach the tube for the airbox...Thanks

I'm curious about this too. All the mags say that the yfz has a better response to the piping mod, but I think that's not where the 450r needs mods. The carb in my mind is what it needs to let out a lot of power!

i thought the crf carb is a 42mm?

The stock carb on the trx is a 42mm BUT it is a Butterfly :eek2: :rolleyes:

The CRF is a Flat slide 41mm and it WILL flow more air and if you want to know how good it works it is what was used on the BAJA 1000 450r:huh :macho

its a 40 mm dude...I have owned 2 of em and have one on order....just wondering on wiring the tps and the inlet extension is all...

i am getting the carb from the CRF450R bike for my TRX 450R. Getting it modified at Baldwins, jetted and installed with his pipe. also eliminated all extra wiring :headlights, taillight, key, fan, and switches on bars. New carb comes with its own throttle and hot start and a new clutch perch. Baldwin Motorsports has more info.

man for 850 tho...Thats alotta dough....The carb already comes with the hot start and you just need the crf cable which is 9 bux...The adaptor is expensive from him i know...

I use a YFZ cable on my CRF quad to use a thumb throttle on my CRF carb. Johnny Hale told me this trick.

I have the CRF carb on my TRX and did make a difference. There is machine shop that is going to make extensions. That I will sell. other than that you need a clutch lever w/ hotstart lever, hotstart cable, and you can wire your plug off your stock carb to the CRF carb the stock throttle cable will work fine. I think I will be able to sell the complete package for around $600-650

[RobRacing]

You can get the carb for around $330 from service honda. And all the other dew hickies that you will need shouldn't be all that much more. So for around $400 you can get the damn near the same thing everyone else is selling for far less.

[robby26wi]

You will need a crf hot start cable,the carb which is backordered nationwide and an extender for the back of the carb...Johnny Hale will have these availible very soon...
