How's the Sidewinder running these days Lorne?  Did you ever get
in touch with anyone who could sell you performance parts?

As far as putting an updated suspension in it, if the track is
the "standard" size, you *should* be able to adapt a modern rear
suspension.  For instance, I'm putting a '96 XTRA-10 rear
suspension in my '90 Indy 500 and all I have to do is drill 4
new holes in the tunnel (at the right spots, obviously).

If you do try something like this, you won't get all that much
improvement unless you put in something like maybe an '88
Polaris, for instance.  The reason I say that is that the
improvement you'd get from putting in an '82 or '83 suspension
wouldn't be worth the work and a much newer suspension, like an
XTRA-10, would be pretty expensive.  So expensive in fact that
rather than do that you'd probably be better off to try and find
an '86 Indy 400.  

You seem like you're pretty handy with a wrench, have you looked
around for a wrecked Indy?  Or maybe one with a blown engine?  
Your Sidewinder is a pretty rare sled, you could probably get a
decent price for it, buy an '86 Indy 400 that needs a new
cylinder (or something like that) and still have enough money to
fix it up.

If you're determined to try a new suspension in the Scorpion,
the suspension from my '90 Indy 500 is for sale.  It's an SKS,
so you'd have to buy new rails to convert it back to a
short-track, but it should bolt into your tunnel, providing your
track is the standard length, what is it?  121 inches?

As far as the front suspension, I can't ever remember seeing any
kind of leaf spring to IFS conversions.  It could be done but it
would take some major re-engineering.  I know the TSS was never
considered a great suspension, but it was better than leaf
springs and it doesn't seem like it would be as hard to mount as
a trailing arm design would be.  It would still be a big job.

Good luck.

I Asked this a week ago but no bites...Does anyone know what suspension I
can put in the rear of my 81 Cat to make it ride better....I would like to
modify the sled as little as possiable.  Someone must remember these sleds

Great if I could get some snow to run on :-)

I know this is a good option but I just can't part with the sidewider so I
think I will keep it for good....I just need to ride it for a couple of
years untill I buy new...hippee.  I don't mind putting a couple of holes
in the tunnel but this is as far as I want to go.  I even thought about
designing my own suspension and cheaked how much to coil springs and stuff
but good shocks are so expensive.

It's a 121 inch track... are there many differences between say arctic cat
and other OEM tracks?  How much is a 90 Indy suspension worth???

I wouldn't convert it to a IFS but would use the old leaf springs...very
hard to explain the front suspension I saw on the trails but here it goes

                           -()-/ shock+spring
                      ___[]___            -()
                  ..''          ''..    /   |         |
               ()'                 ''--()__()        .:
               ||                          ||      .:
    __________/_\__________________________/_\____:

the old leaf spring gets rolled onto one of the three swivel points of the
block.  The new shock and coil spring attaches to the other, and of coarse
the other swivel point attaches to the ski.  By doing this the sled will
be higher so I would increase the ski width by making new mounting plates.
This should give the front suspension about 6-7 inches of travel.

Sorry the ascii art picture sucks but I hope you get the point.

Thanks for responding
