Thanks for the prompt answer.  I was curious why shim was so popular on a lot of inline, 16v, 4cyls.

makenzie71...thanks for answering that as I am not familiar with the EX. The only Kawi's I have experience with are the 86-88 1k Ninja's, and the ZX-10 (the first one) was shims.

GSXR rocker arms are fairly small

I assumed the gix had shims...go figure.  My TLS does.

By chance, have you had the TL buckets out and compaired them to the GS?

no I haven't but I assure you there's no similarity. 90* 996cc 4-valve v-twin.

The motor type does not really make any difference in the bucket design. The rest of the valve/spring assemblies look similar in the service manual. I am looking for options in converting to shim under bucket. Off to TLP.....

yeah there's a lot of people who have torn into their motors hard core on TLPlanet...I really can't remember how similar they were by simply looking at them.  I only had the valve covers off long enough to check clearences...
