I have a 1997 ZR 580 EFI and I was wondering about clutch spring replacements. The sled runs great and clutch engages at 4500 rpm. I have seen replacemet springs on-line and they seem to go by color. If I wanted the clutch to engage sooner (at a lower rpm) what color should I get and what can I expect for performance issues that might make me reconsider. I would like the sled to engage more like my 1995 Wildcat 700 EFI that kicks in about 3500. I dont care about top end speed as I dont go over 70 MPH anyway. (new to snowmobiles and bought both of these sleds just this month)
Thanks much for any comments or suggestions.
