I came out from work yesterday and the oil drips under my bike were bigger than normal. Seems I lost a bolt after a 500+ mile weekend. I thought it was only HDs that rattled parts loose on the highway.
I looked in the hole with a flashlight and everything looks clean to the threads. Apparently the bolt backed out and fell out and thankfully did not shear off. From Max BMWs Parts fiche it looks like I need a Torx bolt M6x30 and a Gasket ring A6x10. Can anybody with more experience confirm this and perhaps give advice for the proper installation?
