If my xs650 sits for more than a day it is very hard to get it started. If it has sat for a week it takes 15-20 seconds of cranking while on full choke. When it starts it sounds like only one cylinder is firing. It has very little power and then the dead cylinder starts popping. Then it starts running with both cylinders and it is fine. If I start it again in a few hours it starts right up. No problem. I do not see any gas leaks.
