We have installed acouple of E-start kits and have the take off clutches. $150/shipping each. No spring or weights. Both are off of 03 or 04 RMK's. One is a 700 w/1500 miles. The other is a 800 w/500 miles. Both had the same part number on the box. I am not a Polaris guy, but I think this clutch fits 600/700/800 engines of this era. Thanks- 00's
