6 spring/ 2 disc. Motor guy says 4500 rpm. Any help with initial set up would be appreciated. Thanks

Red springs, no bolts, .240 spring height should get you real close

Bullerbuilt.net has all the set up specs on their clutches…

buller.net is correct, but I apologize I’m not able to post correct web address.

JPM hit the nail on the head- recommendation puts you at 4600rpms

I'll agree with JP. IF you want to run 1 bolt in the outer, then run the spring height in to .195."
Keep up on checking your air gap though.

I realize this, but sometimes some extra insight is good.
