how many sleds do you have? i think i see a new post from you every week in every brand category. The Cat 600 imo is a stone of a motor, it has been since they produced it in 98 i believe, it gets low mileage and just feels lazy. hell, the 580 that it replaced was not a real winner either but at least it was fun to beat on. I think i remember that the 600 was rated at 100HP so if you are lucky it might have managed 110 with all of that stuff bolted on. I like PS but when they have a failure prone motor that is underpowered from the get-go, it does not help their case.
