Can any of you push the kickstarter through TDC without the decomp? I've just noticed that mine will go through when the engine is cold, but not when it is warm. I think it may be time for a new piston and ring. I figure that the compression returns when the engine is hot because of expansion of the parts. But, the weird thing is that is starts perfectly, runs perfectly, the front still lifts easily and there is no sign of any smoke. Which has me wondering if it's a valve issue. I submerged the bike a few weeks ago, so maybe a valve is gummed up and staying open after the engine sits cold for a week. The decomp cable adjustment is right. First thought was that I've scorched the piston/ring/head when I submerged it, but the compression returning once it's warm has me baffled. A new piston was put in 6 months ago, and it's had an easy 6 months of cruising. Any thoughts?
