I,m in the process of rebuilding a basket case Mk1 349 could anyone tell me the width of the drive side rear wheel spacer ? The one that should have the chain tube mount plate, mine is totaly missing and they never seem to come up for sale.
Many thanks Tim.

The thickness of the rear wheel spacer assembly is 14 mm.
It may be worth trying Dave Renham at In-Motion for parts.
The spacer has two steel parts 5150-046 and 5150-145. The chain tube bracket runs on two stepped nylon bushes 5150-146. It looks as though these parts are common to the 348 and all models of 349.
The latest chain tubes are not made of the same brittle plastic as the originals and last a lot longer. Our 349 is ridden virtually every week and the Renthal R1 chain is only now past it best after about a year, I am sure the chain tubes are the reason.
Hope this helps.

Thats great ,many thanks. I'll drop an email to Inmotion and see what they have. Failing that I'll fire up the lathe and spend a few hours making something unusable before throwing it in the bin !
