Which bikes use these carbs? I'm looking for a replacement for the CV carb on my XR250L. Needs a rejet, and would like a little more power too - so a new carb might be the trick. Something along the lines of a Mikuni TM33 Or a Keihin FCR33/35 (Both with pumper)... Would seem to be the trick - What bikes are these fitted to? Ta, Mike.
