Ok. I need help. I bought my bike last year, found someone had welded the countershaft nut on. so I split the cases and replaced the countershaft. after getting the bike put back together it fired right up and I took it for a spin. one mile down the road it seized up the back end and when I pulled over I realized I never torqued the cct to the head. it completely jumped timing and thrashed the head journals. bought new head put it in fired right up ran great for 30 miles and then valve chatter was really loud. bombed exhaust cam. intake cam and journals were immaculate. only exhaust was destroyed. third head installed by a shop. yesterday at about 50 miles on this head. seized. thrashed exhaust cam. intake is beautiful. I thought there is only one oil passage to the head which is under the intake cam, but im starting to wonder if when I mated the case halves I oozed some yamabond into an oil passage or possibly coolant galley. really im just in need of steering in the right direction. anyone have any ideas what would be bombing my exhaust cam
