i just did a set of stockers last night, i started a topic on it.. look it up and you can see them.. i am not sure if the factory finish on works is the same as the yammys, but if they are i would say about 60 bucks to do them... pm me and we can talk some more.. you will see these springs in person at atiica, i did my buddys bike, cylinders,cases,head,clutch cover, kicker, brake lever,shifter, foot pegs, ner bar mounts, hubs, and springs.. then you can decide if you like the work...
