Could be the fuel filter but I'd bet money on the fuel tank vent. Loosen your fuel cap and take a ride. Don't take the cap off, just loosen it a bit. If that cures the problem, buy a new fuel cap.

Cranks but will not start


You need to check your charging system, if your stator is bad your battery will not charge. As far as it shutting down while riding that sound like you have an intermittent ground, so check all wire connections.

Relaced coil, ignition module, starter relay bike shuts down when hot and won't start


Replace the cam pickup in the nose cone on the right side of the motor. Due to heat cycles over time the epoxy melts and the wires fall out of the pickup. Pretty easy job to do, but you will have to reset the timing on the bike when you are done.

Engine hot


Yes, the R80 has an air cooled engine and may also have a oil cooler to help out with cooling.

First, how do you know the engine is hot beyond what is considered normal? Do you have an oil temp guage? Air leaks around the head and carb connection can make the engine run lean which will contribute to excess heat and poor performance. Check for cracked/hard rubber hose between the carb and headand replace with new if required.

Ride the bike and enjoy it.... just make it a point to shut the engine off if you are stuck in stopped traffic for a period of time longer than 10-15 minutes.

Using a good quality oil in these bikes is also a good idea.

Good Luck!

It has injectors.Does it display any "C" codes when you crank it up? Did you ever tinker any Fuel Injection modules or sensors? Have you inspected/ or visual checked or try to replaced your fuel filter?
