I just put in a new set of points and condenser and cleaned the carb. It starts on one kick and idles perfectly. However, when I give it throttle, it almost dies but then the engine accelerates. It runs great on the center stand, but when I'm riding it has no torque. I tried taking it up a hill that used to be no problem and this time it slowed down BIG TIME and I had to turn back down the hill because it felt like it was going to stall. Has anyone else had this problem?
