My info is this,
I bought the bike cause it was run lean and the fella heard a sound coming for the cylinders, so he shut it off and pulled in the clutch. It was brought back to his house and had the head taken off. It only had 10 hours on a rebuild from the previous guy. The boost bottle had caused a small tear in both of the intake boots, and leaned out to the point where it had melted a small hole in the top of the right piston (maybe at largest the size of a match head), but it had scored the side of the cylinder. As I said though, I got to the guys house to buy it, and the pistons were out so he could show me the pistons and cylinders. I turned it over with the kickstarter and it turned no problem, so we temporarily put it back together ( no pistons etc....)and I left. Its only now after I have started to take it apart and have the pistons out that I have run into questions?
