Hi everyone, I just bought this sled, it is a 1998 formula 3 600 LT with a motor, pipes and clutches from a 1998 Mach 1 (700 triple). Right now the drive clutch has 289 ramps and a black spring with green and pink. The driven clutch has a white spring in it ( factory setup) Helix is a 50/47 I believe. Any suggestions of springs, weights , adjustment etc whould be great.
Right now it has tons of middle-high end ( 30-80 mph). I would like to have more bottom end to middle power ( 0-60 mph), any other tips setup suggestions would be very helpful, like suspension and jetting.
I've done lots of work on Polaris clutches, but none with Skidoo

I just found this forum and it looks full of knowledgable posters. Thanks

If I put this in the wrong thread... sorry in advance to the MODS.

i think the green pink is a 230/380 spring , double check that. if it is than you can use that with 286 ramps and buy some adjustable heavy pins (about 25 bucks) and start with the pins about 18.5 grams. the secondary spring hopefully is beige not white...if its white get a beige one. the 50/47 helix will work and you can set it between 18 and 24 lbs. this makes the most out of what i think you got allready and is a all around trail freindly set up..if you like drag racing well, theres better stuff out there.

Thanks for the swift reply, my driven is a white spring, I had it apart today and its pretty weak, I'll going to order some EPI springs, any suggestions which color to get for front and back??
What is comparable to the Biege from Skidoo?

I prefer the goodwin blue secondary. if ramps are in your budget the 280's are great in drags and aggressive trail use. gr/pi is 200/350 , pi/wt is 230/380. goodwins orange is 245/375, and my choice. if I remember right we had a red215/375 in one that worked good with the 280 ramps.
yeah, i`m a 280 guy too... ive got the set up for you using the epi stuff too. its gonna be the blue primary which is a 240/390, 20 to 22 grams of pin, 280 ramps your 50/47 helix and the blue epi secondary (51/99) at 19 to 24. i would ideally gear it at 23/44 if your not looking for huge mph numbers. i assume the sled is studded right? dooman, i doo stand corrected , i thought i might be off on the primary spring...if you have access to a doo black primary (185/410) thats probably a tadd better choice than the epi blue. happy tuning.
Great Info Guys, I've been thinking of maybe getting a EPI clutch kit so then I will get the diff helix as well. Seem's cheaper if you get it in the Kit. Any feedback about the EPI kits would be helpful.
The EPI kit i think just has the two springs and a helix, no ramps or weights.
I phoned the Dealer today and they have nothing in stock.... so it will be faster to get it mail order. Spent the afternoon giving the carbs a good cleaning and rejetting. (you can probably smell my gas fingers through your monitor :).
Gotta love getting a new sled... Had it for two Days...time spend riding 1.5 hours, time spend fixing in the shop to make it go faster... 6 hours and counting.

I figured that is what you did not mention in your first post. so I had to add if in your budget :) .
for two to three day service to your door check out www.ingles performance.com . almost everything is in stock always. ramps,pins, 2 springs i would guess would set ya back 170 bucks.
Ordered a EPI clutch kit from royaldistributing (up here in Canada) for $179 CAD ( aprox $140 US) should be here beginning of next week.
Thanks for all the info!!
