Can I get a different carb?
If you wish to switch to a slide carb, the Mikuni 38mm RS carb will fit, as will the Keihin 39mm FCR (the 41mm will not fit). This will give better throttle response, but will make throttle modulation more important in low-traction situations. Also, some have had problems with the slide carb; someone tried the Mikuni kit and generally found that you can mimic stock fuel economy but have the engine fall flat on its face when you open the throttle wide. Or you can go way rich, make it run great, and eat gas fast. He dyno tested the bike and actually found a LOSS in HP. He ended up going back to the CV carb. (Like I said, spend your money on suspension!) For a milder stock replacement, you can try a Mikuni VM36 carb; you may need to trim down the intake side, and if the carb was equipped for snowmobiles, you will need to replace the float needle and seat with a set for gravity feed.
