Well guys ive been looking at buying a cat because everytime I hop on one it feels good and does what I want it to do.. I rode a 05 rev once and the guy had some money into it clutch piping nitrous all that stuff and it really didn't impress me at all to be honest it was the biggiest piece I ever rode...But the other day I was riding with a friend and he has A 031/2 with porting and some other stuff and it might have been the best sled I have ever rode I fell in love And well I found one for sale for a descent price and its clean I was just wondering what you guys thought about them and if you have had any probelms...?
