suspension settings - Snowmobile Forum: Your #1 Snowmobile Forum

what are the best suspension settings for general trail riding? on my '85 formula mx, there are two springs/shocks in the rear and one in the front of the rear suspension. they have five adjustements on them. i weigh about 205-210 also. I'm looking for something with better steering at both low and high speeds. acceleration is not main concern, just felt that it was too difficult to steer when i took it out tonight. thanks

Adjust the suspension so it doesn't bottom over large bumps. Adjusting the rubber limiter strap at the front ofthe rear suspension adjusts weight on the skis.

do i tighten it then to put more weight on skis?

Yes, tighten or shorten to shift more down pressure to the skis.

Was it "pushing or scuffing" in the turns or very hard to turn (requiring a lot of effort)?

it was definitaly pushing around the corners. i don't have carbides, just wear bars. it was hard to hold it at a full turn, but thats just becasue it was pushing i think.

First thing then is check the condition of the bars. If they are worn, the sled will not turn.
Carbides are actually cheaper in the long run as they last longer.
If you have any studs in the track, you should be using a carbide of at least 6".
Try this first, if it solves the problem, you do not need to do more. If not, then you need to make adjustments to the suspension.

no studs, and wear bar isn't that worn, but as of right now i can't afford new carbides along with all the other stuff. so im thinking adjustments would be best

I'm not sure on the 'Doo, but most sleds have at least 2 mounting holes for the upper skid mounts.
If so, move the rear arm to the lower hole of the tunnel mount. this will shift more weight onto the skis. If there is not another lower hole, you will either have to shorten the front limiter a little or start by letting a little of the pre-load off the front shock/spring.

Shorten the rubber limiter strap/s as SEG mentioned and also check your ski alignment

I believe on that susension, the limiter is controled by tightening or loosening a nut on the bottom of the front arm. Same idea though, just a different method.
