Rex,
When I rode Cat the torsion spring adjusters looked very similiar (if not identical) and you could buy "overload" adjusters where the medium & high settings were higher than stock. I know Grip-n-rip sells an billet overload adjuster for Cat that may fit to give you more preload.

garserio posted the part number on the previous page. It is 8GF-47336-10-00.

It sells for $54.95 at Pioneer Performance.

The price should be about the same at any Yamaha dealer.

I'll check Grip-n-rip. Are the other ones you mention sold by Cat or are they aftermarket.

I used an older 157#/in Yamaha spring from an SXr. I do not have the P/N with me, but can post later on tonight. However, Yamaha does offer a newer spring with a 168#/in rate and it's P/N is: 8GF-47336-10-00

Attached is a list of Proactive Springs as promised...

All the overload adjusters were aftermarket. I know www.hiperf.com sells a set as well.
