Well, when the bike is warm and idling, when you enguage the choke the rpms race to 5-6K. When initially starting, like first thing in the morning, or at night when comming home from work, the bike will sputter with no choke, enguage the choke and any sputtering stops and it just cranks. I can get it to catch without the choke a hell of a lot faster than with the choke. In fact I havn't been able to get it to fire from a cold start yet with the choke enguaged. Now the fact that the rpms race when the engine is hot shows that its working right? Anyone had this issue before? Even on another bike? I just put in an o ring kit and set the float heights at about 13mm. It was at like 16mm before.
