I am selling my RZR. It has a k&t turbo system and a Big bore kit. It has many other upgrades including aftermarket seats harnesses stereo system control arms custom paint aftermarket bead lock rims and exhaust. It also just had a transmission rebuild with receipts. If you were to add up all of the cost of work done to this machine it would probably run you an additional 15 k. A lot of work is gone into it so save some money and buy it already done! Since I got it I have found that it doesn't reachnover 6500 rpms. I have played with the clutch weights but have not been able to get the RPMs above that amount.
