For the love of god I can't figure it out...
I've done this many of times before on different sleds but I just
cant figure it out????

Do I have to tighten (compress) the spring to make the suspension stiffer,
or loosen (decompress) the spring to make it stiffer?

If I am not mistaken it's tighten the spring for stiffer ride...

The reason I am adjusting it is, because the guy who owned it last winter
was bout 150lbs, and I am 220lbs and the track is studded 192.
I dont want the studs to hit the heat exchangers thus, reason for tightening
the susp.

Thanks in advance,

Morley

"Tightening" the compression restricts the flow of oil during the
compression phase (squeezing the shock) and slowing the rate at which the
shock will squeeze to bottom. This makes the ride stiffer. This does not
mean the shock won't bottom (if you are too heavy for the suspension's
preload - like I am on my bikes), the extra compression restriction just
makes for a harsh ride. Basically if you restrict the flow too much, the
shock becomes a lead pipe and the suspension is not soaking up the bumps.

Tightening will increase preload.

On a used sled you may be looking at new and possibly heavier springs to do
what you really want. That is restore or change the spring rate.
