[QUOTE="kellymac530, post: 4983, member: 115"] mark...you have mike confused with someone else on TT...he is always polite and helpful. been great to me and everyone i saw on that site. back to topic...i ride the same bike, and i follow a number of threads and site on that year make and model...i have over 2000 miles on mine and it runs great...burns or transfers a bit of oil but no top end issues at all....i have never read about any regular nalve issues at all....opposite actually....they have a great valve rep and stay adjusted better than most bikes out there. my guess would be either valve float some how and interference...or a defective valve. if this guy is as hard on things as you say, it is possible he had something loose, and it went thru the carb and stuck in the valve seat causing interference which broke the valve head off....i had that happen on a bug motor years ago when i was ...young dumb and full of cum:smirk: may not be able to figure out the reason with all of the damage...you could try looking at the valve under a microscope to see if there was a fracture prior to it failure. not life or death either way....
