I know it sounds crazy. We are considering removing the fuel injection and installing a new FCR carb off of an '07 CRF and the corresponding TRX thumb throttle on our '08 KFX. The shop I deal with has done the carb conversion for several LTR450's for local Pro-Am MX guys and they perform flawlessly and performance is off the chain. I looked at and rode one yesterday. WOW. Plus, there's no hacking. It's a pretty simple straightforward swap.
I'm considering doing it because I'm fed up with try to figure out what's wrong with my bike. The motor is built, and puts out excellent HP, but will lean itself out once in awhile, and stumbles, sputters etc. Then it will go back to running fine. I know of other race bikes that do this and proceed to blow up which I don't really want to do.
Anyone seen this done or have any input?
