Man, I hate that, I know you just got it back together. Hope you find what caused it.

I'm seeing a little PTV contact on the outer edge of the exhaust pockets. We had JE cut this pistons for OS valves but I'm convinced JE doesn't have their pockets centered. Not sure if that was the main cause or it just helped to float a valve at high RPM. I was playing with upping my shift points the couple runs before this. AFR was dailed in between 13 and 13.2. Jim offered to digitize the head and valve angles and check with JE to see what if anything is off should I do another build. Knowing me, It will go back together with a full out build. I'm really wanting to know how WEB's .410 lift cams work with a 14:1 setup. This motor will be down for a long while for a full tear down and inspection. Have my stock bore motor going back in the bike so at least I can still play with it.
