i just bought thi 98 formula 111 700 and the rear suspention feels like it hard as a rock doesent seem like its moveing at all or very little it does have the after market kit on it im not sure what its called but its to help keep the front from doing wheeles connects the rear suspention together domething like that any ides would help were to start thanx

Could be a siezed or bent cross shaft or shock. I would pull the entire suspension out of the sled and completely go through it checking all shafts, wheel bearings, slider shoes, and shocks. I would also take both shocks off and check to see if that are any good. The original shocks on that sled were the motion control shocks and are probably worn out. Replacing with HPG shocks as I did makes a big difference in ride quality.

The aftermarket kit "A.D. Boivin"?? is to reduce the rear kicking up over big moguls. It does make the suspension much stiffer. The spring on the front shock in the skid must be set as light as possible and the rear should probably be on the second from the lowest cam. They even recommend a softer front spring when using that kit. I found mine rode best with softer/better shocks and no coupling kit.

The thing that controls ski lift is called the ACM and is located down low and centered attached to the bottom of the rear swing arm. The nut is the adjuster. It will also contribute to a hard suspension. Start with this loose and don't worry about it until you have the other adjustments figured out

Try loosening all of the above to see if it helps. I seriously doubt that it will. Even if it does move you should not just trust a used sled. It will work so much better if you take it out and clean/grease everything. Then you will see how it all works. Also look for rust on the shock shafts.


:div20: :div20: I totally agree with this advice!

i think i will do just that and take it all apart looks like only 6 bolts and it comes right out i am brand new to this site and so far very glad i joined thanx for the imfo

Does anyone have a intallation manual or exploded view of on of these AD boivin kits? It appears to me that some farmers got a hold of it and I'm wondering what is missing. The track is contacting the rear pivot arm hard!! need help. The rip in the middle is from when the front shock blew out.

yep. looks like the shock blew out I had the same thing happen! WATCH your track... mine did not last long when this happened!!!
