I have a 05 m7 in fairly good shape but I'm concerned with how it's gonna ride. Everything all around feels pretty stiff, especially the skid suspension. In motocross we have to change spring rates for the riders weight for the optimal ride. I'm wondering if sleds are the same. Keep in mind I am trying to basicly not spend anuthing but my own labor as I will probably only be using the thing on vacation. I don't even think the rear end flinches when I sit on it. I'm a hair over 150 in street cloths. What are some cheap ways I can soften this baby up for me?

Search the forums for "geo mod". The geo mod made all the difference in the world on my old m7.

Try to find a relocation bracket for the front skid shock, it raises the mounting point to the same location as the 07-11 skids, helps by keeping the track from "ratching". I know AMP makes one and im sure there might be some others floating around.

Also a good idea might be to send your shocks out for a re-valve, I've used www.shock-tech.com he is very familiar with M-series sleds. I did those two modifications to my old M and it made a difference

Sleds are considerably heavier than bikes. Especially when they have snow on them. This means a moderate change in rider weight requires less change in spring rate than a dirt bike since it is a lower percentage of load on the suspension. It's more common to have to increase spring rates for heavier riders on sleds than to have to lighten them up for smaller riders.

There are two sets of front arm relocation brackets in the suspension swap meet right now. Turn the adjuster blocks down to the lowest settings on the rear torsion springs. About 4 threads showing under the front track shock preload rings. I'd start there for you. If you decide to spend some money on it, I recommend a Holz re-valve for both rear shocks with their dual spring kit on the front arm shock. They used to offer that package for $190. I ran that until converting to a newer '08 air shock skid. I did swap over my Holz front track shock to the new skid.

Thanks for the help everyone. When they say move the slider back one inch what are they speaking of? And should I do anything with the limiter strapes?

If loosening your shock springs and your rear sissors springs don't help softening up the suspension, I would look into getting your shocks revalved for your weight.

Limiter straps all the way out seemed to work the best for our riding group on the M-series chassis.

Well I'm interested in the relocation brackets. Just check the swap meet and don't see any. Can I post want adds in the swap meet?

Those brackets are fairly sought-after so you'll probably have to check pretty often to catch a set. I think it's ok to post WTB adds in there. I've seen them before anyway.
