OK, Iam going to throw myself under the bus here and let everyone know what went wrong with our 300 mi enduro motor. FIRST Iam NOT blaming the piston yet. The piston is a KB Premium Forged deal, #770 with a 1.395 CH, 36cc dome in a 496 tall deck. They are damn nice units with alot of good features if you look at the pics. The one in the motor is not coated like the other in the photo, and probably should have been. It's also had it's exhaust relief cut, exactly like the coated one, although not very much as the photo of the original piston will show. Mainly it was cut at a different angle, with most of the material taken off towards the top of the relief. It burnt thru right where the little bump is, in the underside photo(not the sharpy mark). That in itself seems odd. The exhaust was cut for another build, with a very long @.050, which the coated ones WERE going to go in, but I am waiting until I cut this piston up and see EXACTLY how thick it is there. Motor was conservetivly rich, 38* timing, 110 Sunoco 6300rpm. If they won't take this, even with the cut, they would never going to take what I had planned for them. THE REASON I am posting this is because I like the abuse Iam going to get from you guys and to let you know if you run these, DON'T CUT EM, and don't spray more than maybe 150. The larger dome pieces seem to be thicker in this area than this perticular part#. When I get it cut up I will let you know what I found, right now I am a little busy getting ready for the Thanksgiving Opener and the Kilo attempts in Dec.
