If you mean to say YFZ, as in the quad carb, you don't want it. It is emissions equipped, and will be a nuisance.

Jetting, air cut valve, capped pilot screw, needle with no grooves, etc.

You don't want it.

thank you SIR
the jetting is the same as on the yz426
165 main
45 pilot
needle on the fourth grove
sounds like even if the jetting was like you said a jet kit would fix 95% of it
it might not be th carb your thinking of the only diff.
is something called a carb. switch two wire deal
ive had both carbs apart as far as inside very close to the same
but again thanks.

With time, patience, creativity, and determination, a lot of things can be accomplished. Sounds like the bike could be made to run with that carb.
