-----Question-----
I just bought this bike used.2002 - 4 Stroke engine. Don't have any manuals. How do I adjust the idle speed? Once engine is warmed up and choke is off, it sputters down to a very slow idle and finally stalls. Also, what is the standard cold start procedure. Choke on, but do you need to twist throttle? or choke on and kick without touching throttle? Any advise will be great.
