My MC21 won't start unless I squirt a bit of fuel into the carburettors, then once that fuel is burnt the engine stops. I've checked there is fuel in the bowls and the throats look clean. I haven't gone further until I have more info as the on-line workshop manual isn't all that clear.
The bike stood for many years in the weather before I bought it, and it took some time to get all the electrics working. It has weak spark but obviously enough to fire the fuel.
I found compressions were low in both cylinders and put that down to the length of time the bike stood idle. A bit of oil down the plug holes brought compression up and I'm hoping once I can run the motor for a while the rings will seal.
My questions are: Is there an electric fuel cut off solenoid fitted to the carbs; How do I check to see if the reed valves are working and would they cause the no-run symptom; Does the PGM control the fuel into the cylinders.
Thanks in anticipation, Wellsy.
