atv questions.......?

[trouser trout]

So my blaster has a couple mods on it,

B1 Toomey Exhaust kit, After Market Swing arm skid plate
G-Force Extended Stainless Steel Rear Axle
ITP Holeshot rear tires
After market hubs
Boyesen Reeds

I was wondering if anyone has any ideas how to squeeze some more juice out of it! It screws now, but it is never enough.

Also I am looking for some good tires for snow/mud?

Any ideas???
