This bike starts out great and runs awesome! alot of fun to ride. But after about ten minutes or so the bike starts bogging out and then lurching and then stalls out completely. You have to wait for the engine to cool down to start it again (about 20-30 minutes) and run it. But the weird thing is is that after it stalls it will idle roughly on choke and then it will start idling really fast and then stall out. It is the weirdest thing. I am running 32:1 motorcycle two stroke with premium gasoline. I've cleaned the carb too and the plug is wet after trying to start it. I also took the plug out after it stalls and it has good spark out of the cylinder. Any ideas? I cant think of anything? I would say the coil but it will idle roughly on the choke after it stalls. Has anyone else had this problem? It also is very smoky after its been running awhile but the first ten minutes after you start it up from cold it runs like a dream. But then after it sits and cools down for about 20-30 minutes it runs great again. I have replaced the spark plug too.
