KTM 450 Valves?

[lucky]

Does anyone do there own major service & valves?
My XCW is well over due having its valves checked & is around the 100 hr mark?

My issue is that i seem to break everything I touch & have no idea what im doing?

My plan is to ask if someone may have the time to teach/show me how to check/adjust them over free beer & pizza....OR should i just get Calgary KTM to do it?

Thanks

Jon
