Well on the last round of the NHHA in Panaca I had a ton of Silt get through the filter and reek havoc on my plug, piston and carb. I tore the whole thing down and cleaned the piston, carb and replaced the plug. I put her together with no issues and she fired right up. Took it for a test run and everything was good. The next day we went for a little put . I passed my buddy and he thought he was riding behind a 2 stroke. He said there was white smoke galore. When i was idling i reved it up and during the high rpm there was white smoke coming out. It smelt oily but the bike also smelt hot. The radiator fluid lowered so I think it is just a head gasket. My question is.... should I just replace the head gasket or get a new top end or rings just in case? Any other things you guys can think of to replace or look at?
