OK OK. Sorry for the description, but its true. First of all, my friend is not internet savy, so I'm here to help him out with his Firecat. We both have stock machines with 144 1.08" studs. The trails we rode today were in need of grooming but overall ok. The supension on the F7 is so soft that he bounced all over the place and could not keep up with me at all. If you push down on the back seat you can almost bottomout. Also, the seat may not return al the way to the original position. I went for a ride on it myself and it was difficult to control the machine. We both weigh about 200 lbs. We plan to work on the machine tomorrow to improve handling, any help as to what to adjust?
