Another question for the group: How can I rule out an electrical issue caused by temperature? This may not be a soft seize issue at all. The bike fires up and cruises great for five minutes or so and then starts the routine of dying out until it cools down. I'm a points and condenser guy so I immediately think about a failing condenser. This is a CDI, something somewhat foreign to me. I swapped out the CDI for a JOG CDI with no difference. I swapped out the ignition coil with no difference. I tried another carburetor with no difference. I replaced the crank seals.
Its either something that I don't understand regarding the 60cc kit or its ignition related (something that I suspect). The stator coils are low mileage (700 miles). Are these prone to failing under heat?
P.S. - I don't really think the motor is overheating. I only have a handheld lase and the max temp that I saw on the head was around 315 degrees. I've read on this site higher functioning temps.
