Have you tightened your 10mm exhaust acorn nuts lately?

No but it's probably time. Thanks for the prompt. Them are sneaky little suckers

[John Schmidt]

No....'cuz I replaced them with regular nuts 'n lock washers years ago. Haven't come loose since. Reason was simple, I found the acorns often didn't screw down tight enough before bottoming out...which prevents a tight fit. Probably due to the studs not all being screwed in all the way, something I wasn't going to try and correct after being in there for all that time.

Done    Both bikes.  Needed it.  Also did all the intake runner clamp screws.  Dont forget them.  Doubt you can put any locking mechanism on them to keep from having to check em
