09 D8 Clutching for Cooke City

Pro-8250

I have on 09 D8 with full SLP exhaust, and was wondering if I should run
10-60(8,000 to 10,000ft)
or
stock 10-62(6,000 to 8,000ft)
 
clutching

I ran 10-62's with the stock spring and slp single, 8200 all week in cooke, Bro ran 68 mtx's with the one gram outer hole (slp recommended) and couldn't get over 7900....... but all 800's are different IMO....
 
As others have said all these 8's are different......i couldn't pull 62's at 9000, i would start with 60 and if over rev'n switch em out!
 
i was running stock springs with carls helix and Ron's 59g weights and still wasnt pulling over 8150 or so.
with a slp pipe
maybe i just have a pooch
 
I have an SLP single and last year in Cooke I ran Carls helix and Rons 63.5 gram weights and the sled ran great. Started with 62 gram bellybusters and they were to light. I am in Cooke right now and started the first day trying different combinations of weghts..10/62/, 10/64 and 62 gram belly busters. Used a less aggressive helix and red spring in the secondary. Sled just did not seem to run well. 7800 to 8000 rpms. Went back to Rons 63.5 gram weights with SLP green/pink in the primary and put my Team Tied helix back on with the more aggressive helix and the sled pulls like a freight train. I ride with 8 other Ski Doos and none of then can beat me in a race on the hill or on the trail. Sled pulls so good from a dead stop. Torque is awesome. Has been a great week. Also running a 2.5 Challanger Extreme track and 19/42 gears. They also help.
 
team tied choices

Could you tell me what helix and spring you ran in your team tied clutch and do you have a number to get in touch with Ron about weights , Thanks.
 
I am running the 73/57/.46 and 73/59/.46 helix from SLP. Using the 59 cut right now. Also using the stock helix (black/purple I think). You can get ahold of Ron by pming him on snowest. Make sure you use a capitol R.
