Polaris Sportman 90 Help!!!
Do some searching on "Sportsman 90" and you should find some threads that will help. Searching on Mini ATV's in this forum will help too.
This topic has been covered several times.
Basically, though, in answer to your questions, there are modifications you can do to your engine, exhaust, transmission and suspension that will greatly improve your mini's performance. I've heard of mini's that can go 60mph so it's not out of the question. I'd consider some suspension mod's along with it, however, to be sure the machine can handle the speed.

There are kits you can buy for the tranny that change it's engagement points and such. I won't pretend to understand it all.
Performance links for Kid sized ATVs....
Rhino accessories from Keen Perception (I ordered the oversized cylinder from them)
Mini Quad Racing
Mini ATV parts
Trinity Racing
Hetrick Racing
WRH racing
These are probably only scratching the surface, but they'll get you started. Be prepared to spend, though. Making a race ready mini cost almost as much, if not more than the mini cost originally!

If you want to go that fast, it would be cheaper to buy a Yamaha Blaster and have 2 quads. Just a thought. We have been very happy with our Sportsman, but when it's time for our son to go a little faster, we'll just buy him a bigger quad and pass the Sportsman on to our daughter.

Overkill has a very good point, too. No matter how much you modify a 90cc, it's unlikely to ever match a blaster in terms of suspension and potential (particularly with the Blaster's aftermarket).
I may do a few more mods to my 90, but then I have a few kids that can grow into it yet.

Wheel spacers will improve the WIDTH, not the Wheelbase (that's the distance front to back). You'd need an extended swingarm to improve the wheelbase.
With the oversized cylindar my kids report an increase in power, but the top speed has been unaffected. Adding a pipe will probably further increase the power. Speed, I believe, is limited more by the transmission than the engine.
