Thanks...that's a help. I may well try that one.
At the moment my usual supplier isn't listing cush drive rubbers for the TBS model...and is listing for my 07 Speedmaster...so I've ordered that for now but will look at a more satisfying longer term fix in the near future.
Interestingly this is my 4 th TBA/ SM and the only one to have suffered this problem to date...and at only 7k miles too.


I took the Road Less Travelled. Now where the ****** am I?
