I agree with newz somewhat, but I think the purpose of this forum is to help others out that don't have the knowledge to jump in to some projects.

Guys I know what im doing. I was looking for a techincal term. Its working or should i say did work for 3 hours. It ran outta gas and would not restart. I checked everything for spark, changed the plugs ( one of them looked rich the other was smelling like gas) It will run for about 1 min but horribly on 1 cylinder and barley stays alive. It also is spitting gas back up through the throttle body into the air filter whcich leads me to beilve its possible a exhaust valve is stuck.

Kodiak956 check your valve clearance.

Intake valves min .006 / max .008

Exhaust valves min .009 / max .011

Sounds like the intake valve is sticking or the clearance is to tight.

Valve Seat

The engine you posted model numbers for is an opposed twin, these engines have had a history of problems with the valve seats coming loose, this could cause a problem similar to the one you describe.

Determine which cylinder is causing the problem and remove the cylinder head and inspect the valves, seats and overall condition and you should be able to tell what is causing the problem (loose valve seat, stuck valve, excessive carbon build up, etc...)

Thanks 30 year tech... You would not happen to have access to a service or repair manual would you? What is the fix to these problems... how hard and long do they take and how much money? Is it worth doing my self?
