I have a primary spring from a 96 800 storm its not in any books I have. it has 2 purple and 3 white coils. it mesures 3.750 free height w/.207 wire dia if any body knows the brand, spring rate.ect it would be great thanks

most tuning shops have there own colors codes. the spring height you mention may not be accurate if the spring has taken a set,but the wire diameter and the number of coils should help
