As I have never experienced this sort of rattle at any other bike in my life it made me take the rear hub to pieces on my newly bought Norton Commando 850 MK3 two years ago. It sounded to me as if something must be wrong in the hub. But I figured out all that what is exolained in this video when I looked at the interiors of the hub and found this loose plate with lots of play which doesn't seem to fit to the otherwise thorough engineering of the bike. I gave it a little bend to stop it from rattling, changed the rubbers and put everything together again. I am sure this strange noise would have caused a lot of questions and critical comments when noticed from some spectators on a classic bike event in my region.
Have I got anything like this setup on my '72 Roadster? On this winter's "to do" list is changing a worn back tire, and this will be the first time I've had it off since I've owned the bike. I'm also toying with the idea of putting a modern chain on the bike, so things like spacing have now caught my attention. Colorado Norton Works makes a nice chain setup that if nothing else allows you to delete the little oil-drip lubrication setup that's stock to the bike. Thanks in advance for any insights you may have...
Hi, Ashley. I've got a plan for installing the Isolastic conversion to vernier adjusters on my PR this week. Does the blue lube for motocross tyres work for inserting the rubber buffers into the Iso tubes or do you recommend another product for this? Thanks, BH
Thanks, now I know where the noise comes from while moving the bike and that this is an usual thing. Cheers
Glad we could help
On the 1970 commando the cush drive system looks like it will not work very well with the 3 points of contact and small rubber inserts.

Ash's response: The cush drive in the video is only found on the MK3 Electric Start Commando, the 1972 model uses a different system.

Ash's response: The better option for the isolastics is red rubber grease part number - GREASE/RED
