Title: Easy shim Q: 29.5 mm?
Post by: conflicttheorist on November 29, 2004, 02:10:23 PM
Can someone tell me whether the 29.5 mm shims used for most suzukis are the ones I should use for the GS500 as well?  Thanks.

Can you use the dial caliper in the valve adjustment toolkit to measure the diameter of one of the shims?  (DON'T measure the ground-down 2.15 mm "test shim"!   :roll:  )

hmm, maybe not so well known.  Let me ask in another way: Does anyone know if the Shims from any other suzukis are interchangeable with the gs?  Of course, it would be safer to know the diameter I guess.

All GS series two valve engines use the same shims.  I do not know what size is uses by the GSX or GSXR series bikes - but they are not likely to work on the two valve GS

Suzuki is the only company to use a larger diameter shim in their motorcycles up until about 1990 when they did engineer one of their bikes to accept the regular, quarter-sized shims that the other three manufacturers were using. I cannot remember what motorcycle it was.

And you definitely cannot use the teeny tiny shims that they use for shim-under-bucket bikes like the GSXR's.

OK GS shims are larger in dia and I believe 29.5 is the right dia ... the yamaha XJ shims will fit in suzuki buckets, and visually look identical ... them being 29 mm... I didn't even know I had a pile of yamaha shims in my suzuki collection till I stacked them and saw some were smaller ... D-oh...
Cool.
