I just brought this home Friday. I cleaned the carbs and reset the floats to be level with the bottom of the carb since I had no way of measuring. The bike will start after cranking for ever but it will not idle and simply sounds very sick. I can ride around the NH but have to constantly work to throttle to keep it going. I check the plugs, they are wet and black, I don't think it's oil it seems to be gas. The cold compression is about 105 for both cylinders this is not with the throttle open. I didn't read that until today. Thoughts?
