I broke three main drive belts. I finally replaced the belt system with a chain system. Now I broke the exhaust studs one each front and back cylinders. Seems to me that I may have a problem? Has anyone come across this problem in the past? Is it possible that my engine is twisting? Can some one tell me where I can get a JIMS Exhaust Stud Drill Fixture? Has anyone ever used Time-Sert thread repair? How did they hold up?

I don't claim to be an expert but loosing three belts (over any period of time for that matter) is almost unheard of. Of course unless you do wheelies around the clock! Something is messed up with the way things are lining up in your drive train. The broken stud is a whole different story and not sure if related to the other issue.
Sorry could not be of much help.

I have used helicoil thread repairs a lot. Never heard of but googled the time serts. I don't know how either of them would hold up to the vibration of the motor but we always used helicoils on aircraft and used some loctite with it. The helicoil actually expands into the hole, might be a better option.

The Jims exhaust stud extractor works well.
Usually the broken stud comes out leaving perfect threads, no see for a Helicoil or Time-sert.
For those that don't know, a Time-sert is like a Helicoil but has a shoulder on it instead of threading all the way in like a Helicoil.
Many prefer the Time-sert although they are more expensive and you need to counter bore the hole so the insert is flush with the surface.
A Jims tool is cheaper than removing the head and having a machine shop do the job.
