90-105 depends on compression and clutching track studs ect.
about 100 mph I've had mine up to 120. it ran that speed for a short time then burned a piston down. you might not think it counts because i have to rebuild the motor but that is fast
depends on your area but around $1000-$1600 depending on condition and miles

I have a 2000 XLT and it was located on top of the rear differential...10 minute fix
with only one person on it about 138 mph and if its two people the person it the back makes more drag. but imporves the grip of the traks traction makeing it have a more accurate reading on the speed its about 125 mph. i own three of these xlt 600s and i have raced a xlt 800 and we matched the same speed so there isn't much of a difference in the sise of engins its all in weaight and terrain and how you ride and how you treat the 400 horse power beast
