This problem existed even with the stock bearings when using the non-S triple 
clamp. The fellow who answered the phone at GPR claimed that the S model triple 
would solve the problem. I just need a little more thread to feel comfortable 
that the nut will hold. I'll use red loc-tite as well.

Would it be ok to machine down the round pedestal on the bottom of the non-S 
triple? I know the surface would have to be pretty flat and smooth. That's why I 
would go to a machinist, rather than using my dremel tool.  :)

Anyone ever heard of this being done?

I ask because I have a spare non-S model triple clamp, and I would prefer to 
spend 50 bucks on machining costs, instead of replacing the upper and lower 
triples. It sounds like less work for me--unless it doesn't work.

What would you do in this situation? I would like to remain WERA Superstock 
legal, so gixxer front ends are out.

P.S. I'm also pinging Andy P. off-list about the S model version.
