2002 with 6400 mi. After tuning the bike up , i.e., air filter, oil, plug, valve adjustment, the bike doesn't cold-start easily. I've developed a routine to get it to fire within 5 or so tries. full choke, turn it over for a couple secs, then 1/2 choke, turn it over, then no choke, turn it over... by the time I've gotten to step 3 or 4 she pops weakly, and finally starts, usually on 1/2 choke & then I feather the thottle to get the revs up.



I've also played with adjusting the idle speed screw, and I took the bike to a local mechanic to get his opinion on the valve clearances - thumbs up. Bike starts pretty reliably when hot or warm. What else can I adjust or check? Any advice is greatly appreciated! The bike started easier when I bought it, & it had 1/2 lb. of bird seed in the airbox, original plug, likely never serviced, etc. Should have left well enough alone

What's your mixture screw set at? The stock specs are very lean for emissions controls.



Mine (96 with the different carb mind you) started much better at 4 turns out than the factory setting of 2.5.



Your bird seed in the airbox might have done the same thing by restricting the intake and making the mixture richer.

I will check the mixture screw tomorrow. Thanks for the suggestion!
