Sled: 2000 Zrt 800
Does anyone have a chart that tells the rates of oem cat clutch spings? I think I've seen one on here but I can't seem to find it. Also if I install a spring that is rated say for 5000 ft elev, what will it do instead of a spring for 0- 4000.?

primary or secondary. or both??

usually, the higher elevation stuff, makes the sled a little less aggresive, since it has to work harder up higher( powder snow and less air) the sec springs and helix's are not as tight, and are less aggressive... the primary usuall has less grams of weight which means a lighter spring...

whats your idea of using them at sea level??

I would like the charts for both. I am at 1319 ft. I bought a 2001 zr 800 that the origanal owner raced and I'm trying to put a clutch setup in it that is close to stock for trail riding.I'm new at this so I thought that finding the set up would be cheaper then buying a clutch kit? Right now I have a black prim., black and purple sec.,51 helix, it had a 50/38,and it has 80 gram weights. I'm thinking of a purple prim,71.5 grm weights, red white sec and 55/53 helix.This is 900 setup .Will it work?I have found parts are cheap on ebay or buying used to play with.What do you recommend.
