Re: 72 Commando clutch - seen this setup before?

Forums

Going through the huge list of things to do on my none runner. Clutch completely stuck so cleaned all the gunk from the housing and inspected the plates. The fiber plates look pretty wrecked. But as a Norton novice I canât find any information suggesting this setup is correct, i.e. 2 fibre plates and 2 other (maybe Barnettâs?).

So what are people running on 750âs? Iâm thinking of swapping it all out and was thinking of upgrading to the bronze option and maybe even the 5 plate setup instead of the 4?

Bike history limited but it was in the USA for most of its life.

Stack-up of the plates in the housing looked ok.

Looks like you've got pick-and-mix there, and some DPO's had such a hard time with clutch slip that they've tried scarring a friction plate for grip! I've never had a 750 with fibre plates, so maybe ignore me â but I love the set-up with bronze plates, one of the best and longest-lasting clutches I've used and worked on, on a bike. The only fix I've needed is Dave Comeau's oil seal on the clutch end of the mainshaft â which removes one source of clutch slip. In the UK it's sold by N*rvil under part number 068833, although I see they offer an alternative type 068844. From personal experience I know mainshafts vary, maybe the second type helps when the first doesn't. But maybe someone here's tried one â??
