I Just put in new rings and cam chain. Put the bike back together and it started right up, took it to the track and it ran great or so I though. Motor felt great down low but when I would get high in the RPM it would seem to cut out. Carb issue I though. Messed with it a little and thought I had it worked out and was going pretty good on a section in 4th and then "blahhhhhh" "pop" dead. I was unable to get it to start back up after that, new plug and all. So now I have found that I have no coolant and no spark. Checked for TDC via screw driver method, all good there. Looks like the coolant is mixing with my oil, guess that could be the head gasket, no big deal there. So I guess I'm stumped with the lack of spark. I did DC the kill switch to rule that out. I have read through a few other threads but does not seem they had the same isue as me. I plan to check the woodruff tomorrow.
