My clutch was pooched last year now im putting together a new one just wondering what you others are running for springs and such

My sled
780 high comp head running ll100,21-44 gears 10 tooth extro's, stock secondary beigh spring set to b-5 i believe gotta look again strait 50 helix. 141 2" track, ridin mostly around 4000 to 6000ft, pipes that like 8400 to 8600 rpms.

I have 286 ramps in the primary now and stock arms and pins not sure what they weigh thow with a worn out green-pink spring 200-350.

I would put a cat secondary/red/white spring,47 or so helix and polaris primary w/56 or 58 gm and a blue spring.Ditch the skidoo secondary for sure.I run my 809 at 8600-8800 w/ similar set up at high altitude.

I would just give specialty sleds a call in your area they will be able to help you from here,its a relativley easy mod ,just a little machine work to the taper on the clutches.

I run 286 ramps/200-350 spring/adjust weight to your liking. I run a Hyperlite now but ran a Cat roller before that. Both were better than the Doo button.
Go with a Cat secondary, Cutler R/W or Cat R/W. I liked the 44/42 or 44/40 cam.

I run the Polaris primary with the Almond Red spring and 56 to 58 gram weights depending on snow condition. I also run a roller skidoo secondary off the 440 racer with a 47 degree cam and Goodwin blue spring in the b-5 position. It works pretty good to spin 8800 rpms. I run around 6000 feet most of the time. This was running the 151 track so I my have to adjust this year running the 159.
