Hello, I'm having problems with 1980 CM200 Twinstar. There have been problems since I've put the bike away for winter. I tried today to start it up today, but the bike was not having it. The bike just keeps turning over but never fully starts. I cleaned the carburetor and even sanded the spark plugs. Now the bike will idle just fine, (after many kick starts) but every time I try to give it throttle it just dies. Somehow during my frustration I switched the signal light on and now when I pull the throttle the bike responds well. I turn the signal switch off and the bike just dies again when I give it throttle. Any guidance to solving this problem would be much appreciated!
