After doing a clutch friction test I removed the locking pin from the engine and there was aluminum in the threads on the pin. Replacing the bolt and found the hole stripped. How do I repair it?

    Depending how damaged the threads are, did you try running a tap through and see if it is ok after that?

    If not OK, a Helicoil would be the best solution. Not sure how you would drill/tap and keep the shavings out of the case though. 

    Maybe there is enough access if you pull the #2 cylinder?

    This is one bolt hole that Rotax will allow a thread insert like a Helicoil or a really good one is a Timesert.
