Looking for answers on why this happened so it doesn't happen again. It is a 3mm sleeved big bore to 72mm full ported that turned 20 to 30 hours before this. I was in Halsey for a three day ride and noticed it didn't seem like itself the last day and I also lost headlight sometime out there. Didn't think much of it as it still ran pretty dam good. Got home cleaned filter replaced plug cleaned carb and it lost spark on wide open run down the road messing around. I post more pics after I tear into this more. Looks like crank, flywheel, stator are all toast...hopefully not anything else as it still had plenty of compression after this. Anyone gots thoughts??
