[QUOTE="Jim G, post: 392493, member: 21351"] I just changed from the four strokes to a 2000 250 EXC. I feel that I got extremely lucky. I can unload the bike, turn the gas on (no choke), Starts first kick. I think that the previous owner had just installed a fresh top end and had the bike properly jetted. The jetting would be the first thing that I would check, if that does not take care of the problem, may be time to redo the top end. My bet would be the rings, when cold, causing a loss of compression. When warmed up, the rings expand to be a little closer to spec and allow for easier starting. [/QUOTE]
