By comparison the same measurement on my R100RT (1994 33,000 miles) showed no more than 2 mm lateral free play (more miles but less gear changing wear and tear?). After the modification the end free play on my R65 was about the same as my R100RT.

I used a 1/2-in id, 3/4-in od, 0.032-in peel-away shim (McMaster Carr #90805A162). I ended up peeling away three 0.002-in layers. I simply took the lever off the ‘bike, trial-fitted the shim a few times and stopped taking layers away once I had a non-binding fit. This really was a ten minute start to finish job.




What a coincidence! Just yesterday I took the shifter assembly apart to have a closer look. My findings were the same as yours. I actually used a couple of "beer can" shims to accomplish the same outcome. NO MORE SLOP... and not a penny spent.

It's good to see others doing the same thing. Makes me think I've done something right.
