Iv'e ran them on srx's but has anyone tried them on sx twin 600's for about 2000ft runs.8ca or ab's don't have the top end.

Not sure if a twin has the suds to pull them, you'd have to be pretty light on the helix to make it work I think...Sure would be fun trying!
If you run 89a-10 in a 600 twin you will need about a 43 or 45/39 helix with a p-p-p primary spring & 3 engagement shims. You may need to add a little tip weight.

89a-10 were the best ramp for topend in the old 96 v-max 800 when used with 14.5 mm rollers ywy spring 45 cam.
