First off I hate the 1st gear in my 450 but if I gear it I will run out of speed in the dunes so say I install the clutch and keep the stock gearing and I go for a ride in the mountains will riding slow in 1st gear and slipping be hard on the clutch. If not or so how long should one of these clutches last and whats the cost of a rebuild. In the dunes I tend to use the motor to hold me back alot in the steep hills so can I still do this with the z-start?? Last question can I still use the stock clutch when on a hard pull in the sand to shift or to roost my buddys just like a stock clutch lever?? and one last thing will it slow me down on a hard pull in the dunes or when I am acceling I would think the holeshot would be great but I have never used one. Does anyone have any downsides?? Any help would be great.
