Sorry for the delay guys, was admonished elsewhere on this forum for buying some pretty blue anodised brake reservoir lids.....
Just to reiterate, I have Lightech rear wheel adjusters (they are blue anodised aluminium too :tongue-new
fitted on my Gen 3, when I fitted them I had the devil of a job putting the wheel back, especially with the original 2-3 mm thick washer on the Cush drive side.
When I took my bike in for a 12,000 mile service earlier this year at the main BMW dealer, Barnstormers in Alton, they presented me with that same washer from the Cush drive side and told me that as I had the Lightech chain adjusters fitted, I NO LONGER needed the same 2 or 3 mm thick washer which I had fitted between the frame and the Cush drive side of the wheel bearing. In fact, when I removed the rear wheel myself and refitted it 2 weeks ago, it was simpler without that washer and everything went back together inside 10 minutes which I now claim as a World Record as it took me 3 hours when I was trying to squeeze that same washer back in place before.
If memory serves me correctly, the Lightech rear wheel adjusters have a 'spacer flange' on their inside, adjacent to the Cush drive side wheel surface which the stock adjusters don't have, I am guessing and this is pure conjecture that this additional spacing on the Lightech rear wheel adjusters negates the need for that same washer?
Hoping this helps.
