Only the Polaris springs will work on the Kawies, the weights have different sized mounting holes.

 

got the epi pro kit on my vforce works great hits kinda hard on take off, but the kit grabs the belt and its hooks up im satisfied with the kit. now i need a cdi box and a k&n filter to wake the motor up. there is power to be unleashed from that big twin. the kit came with a red and black springs.
