As I was running in my new 91CD the exhaust pipe loosen up and droped down. I retighted the exhaust pipe when is was warm and it came loose again after about 15 min. of run time. Can a locking compound be used on the exhaust pipe threads to prevent this from happening again?

Thanks,

Jim Stroud

Hi Jim

Thanks for your email. That is unusual for the 91CD. You can certainly use a locking compound on the exhaust though, such as loctite.

If it occurs again, please let me know as this would be covered under warranty.

Best regards
