okay, where the dome is on the head (where the flat part of the valves sit) the intake is uneven and the air+gas mixture escapes threw the open space when the piston goes up into the compression stage, and ignites shooting flames out of my exhaust port. the space is small but u can see light threw it when the valve sits there. Would some kind of Liquid metal work? or gas+heat resistant epoxy work to take the place of the missing space? I would file it but that would not be precise and time consuming, and i would buy a new head for $150, but the dealer doubles that price! and no way am i paying $300 for a new head. any comments would be well appreciated!
Get a valve job - cut the valve seats and lap the valves.
Do as Guardrail Jim says. Liquidmetal won't take the heat.
take bike to dealer and get it fixed right.
Without knowing actually how big the space is, I'm hampered in my answer. If the valve isn't bent, you may be able to lap the valve and seat. Your service manual should have directions on how to do this. Or you may even be able to grind it out with valve-grinding compound. I've gotten away with using valve-grinding compound heavily in some cases that probably should have been lapped. I put the valve in it's guide and attach a rubber hose and drill to the end of the valve. Then, after applying the compound to the seat and valve, I spin the valve while gently pressing on it's head. I keep adding compound as needed. I've done several this way with no problems. But if you have a big gouge you will probably need to get a lapper.
