valve shim buckets

[davipu]

so what I learned today is that from 89-93 suzuki used a smaller intake valve shim bucket and that after 93 they used the same buckets for both the exaust and intake.  and that 94+ buckets will not fit into 93- holes in the head.

and the small ones are on permanate backorder.

I just got back from stockers down in chula vista, not only are they different sizes from 89-93 they were color coded also. then after 93 they were just color coded.

I have a '92.  This past spring, I replaced 3 of the shims, using some from Srinath's valve kit, and some I bought from Cycle-ReCylcle.  I had them all stacked-up, and they all looked the same size (maybe the old smaller size?).  Except for the "test shim", which was an extra-thin Kawasaki shim.  That was a little smaller around (0.5mm, if I recall).

But I didn't notice any differences is diameter of any of the suzuki shims.

Yamaha's have that samller dia shim (XJ, FJ series bikes) now kawi's also may, I never owned a Kawi shim bike I believe. The ninja and eli's are all threaded, KZ is also threaded, vulcan was hydraulic ... My Maxim does have the smaller dia one I know. Anyway, shims are all same, he was talking about OD of buckets, and they got larger after 94 on intake side ... and apparently color coded.
Cool.

Suzuki is the only company that decided that it would use a larger diameter shim for it's shim-over-buckets, that way you would have to take the bike to a Suzuki dealer to get the valves adjusted. The other three manufacturers were more customer-service oriented by allowing shim adjustments to be done at almost any dealer in the nation (or world), so if you were riding your Yamaha across the U.S., and you needed a valve adjustment somewhere, you could go to any Honda, Yamaha or Kawasaki dealer and have it done. Conveinient! And, conveinience can allow reliability (and customer satisfaction).
