[QUOTE="Gary Gittleson, post: 176754, member: 3625"] The later BMWs also have the chamfered rings with aluminum nuts. I have an '82 RS with that setup. It's "standard" procedure for these bikes to remove the nuts once a year and re-lubricate the threads. That's probably more frequent than needed but easily accomplished, unless it's never been done and the nuts are frozen on. I worked in a BMW shop many moons ago and had lots of experience with frozen ex threads. Sometimes, the only solution (after trying heat, penetrating oil etc.) is to carefully split the nuts without cutting into the threads on the head. One important difference between the BMW setup and the Vincent's is that on the BMW the pipes are a very close fit into the exhaust ports and push in quite far. Sealing is hardly the problem with them. I think the function of the chamfered rings is more to clamp the pipes in place. [/QUOTE]
