Here is my Kstar kit, it has a hi comp head, the 70cc kstar jug, piston, wrist pin, brand new still wrapped gasket kit and ring, (and circlips if i can find them) I was driving home and the engine started to squeal so I immediately shut it off. I let it cool for a while and fired it back up to make sure the engine wasn't tight. It fired right back up but still squealed. I think the wrist pin got tight in the piston preventing the piston from pivoting, it was hard to slide out of the piston and crank. Looks like it wouldn't be too hard to clean up. As the pictures show, the cylinder and piston needs some cleaning up. I purchased a new gasket set and piston ring from treats and haven't had time to get it cleaned up and back together. I've been too busy now that school started again. Buy today and I'll ship tomorrow.
