  1. Ktm mx 250 idle problem.

    General Discussion
    the bike is a 1994 MX model fitted with a keihin carb. the idle set and choke are all in one. ive tried everything but the blooming thing still wont idle. the bike runs 100% and is terrifyingly fast. can anyone think of anything else?. dont realy fancy trying different jetting as is runs great...
