My exhaust lockrings look like crap, frankly. Cheap. Out of sorts.

Lockrings

Anyone here know of a source that makes a higher quality version? It's a '71 750.

Cheers--

I use the Bronze lock rings from Norvil, they are based on the standard pattern but the bronze colour looks attractive and as they expand at a similar rate to the alloy head they definitely stay tight.

Cheers dave M. Will definitely check into that source. Mine just look like an after thought.... Mucho appreciated.

Wrench,
Those are 850 nuts on your bike by the way. Original 750 components have smaller fins and look a bit more "Nortonish"

More important, the 850 nuts are shorter and require the split collets, where the 750 nuts fit directly against the header flange.

I have seen several 750 pipes using 850 nuts and no collets with two or three exhaust gasket rings piled in between the flange and head. Not a good idea to keep the pipes tight.

I haven't tried to remove mine yet so not sure what the previous owner did. It would not surprise me to find them jerry-rigged somehow. Nice to know it is not the proper part for the job, though. Thanks.
