Well, two hours before my initial hour mark to rebuild my bike, the engine went... bummed, but the bike was bought used and I put a solid 30 track hours on it. Piston skirt broke. I shut the engine off before it destroyed anything else, though it was already to late. So, the bike needs a top and bottom end. Cylinder looks fine, other then a tiny mark towards the top on the cylinder. Looks like it will hone out though just fine. As I'm rebuilding this thing I want to go all in of course, since its already getting the bottom and top end. I'm looking into Eric Gorr. His Port & Polish work and also the 265 kit as another option. Who has all used him? Both Big Bores and Port jobs. If you guys have pics to post please do. Be nice to see his work. Another reason I want to send it to him is bc I did have some detonation problems and I hear his work will fix this? Any input is awesome.
