I have a 2003.5 900 mountain cat 151" that I bought and checked the clutch last night and found out that there are small cracks in the towers between the weights and on the face plate. I am going to get a new clutch and am wondering about what weights and spring to use. I have the sled geared to 20t/45t and will be riding at togwotee but also around Minnesota where I live. I know that I will need two set ups for the elevation change. my secondary is a 53-55 degree helix and a blue spring. any input would be greatly appreciated.
