High altitude clutching

[hyperduc]

I had planned on going with tri city polaris, but their set up is just as far behind as the cat demos last year were.

Anyone else have a good 8K+ clutch set up ?

I just took out the factory 62 weight and put in 60's and Black and purple spring in the secondary. 2012 155 Pro. I never have even rode it yet?

Same set-up as above, same sled. Factory primary spring. Seems to work pretty dang good. I rode mine back to back with a Carl's set up and I preferred my set up more. I noticed the blk/purple seemed to help hold the rpm's steadier. Generally pull about 8100-8150 at around 8000-9000 feet. Sled actually over revs a little down lower in the 6000 foot range.
