When I pull the choke out to start my 01 KX250 while cold, the bike usually starts on the first or second kick, but the engine races/screams until I push the choke back in :yikes: . I've owned a lot of 2 strokes, but none of my other bikes acted like this. If the bike is warmed up and I pull the choke the bike revs faster but it no longer screams. Anyone have any idea why the choke would cause a cold starting bike to rev so hard at first?
