[QUOTE="MXP1MP, post: 165459, member: 20581"] What color is the smoke? is it smoking excessively? Does it back fire on start up any? Does the plug look rich in color? Is there any water in the oil or coolant? Maybe the gasket has blown internally. Its had about 15 tanks ran threw it so thats about 2-3 hrs per tank so around 30-45 hours on the top end. Its also possible the ring is toast. make sure all the fuel line hoses and the crank case breather hose are unclogged. I hope the fliter is clean and not the oem one still. I really doubt its electrical. if it was a bad main seal it would just be running really rich and be loading up on the bottom end and could get burbly and refuse to clean out after a few good rev's. A bad main seal won't really make it run like crap on top it can but its not a constant thing more like once in a great while. Maybe the reeds have hair line cracks but that usually makes the bike hard to start. I think you'll be better off checking out the top end. [/QUOTE]
