I'm pleased with my single HMF slip on, but DMC's are my favorite duals (if I had them). Airbox mods are just as good (but free) and my pink EPI primary should arrive via UPS tomorrow. You probably dont use paddles in NY so Ill stop here.

 

yea i never rode in sand... do you kno if yoshimura TRS are better then the aliens? tell me how you like that pink epi primary works.

 

anyone kno what the best primary spring i should us? i want the best for draging and i also race around here wid friends. but i trail ride some so i dont want the spring to be too jerky. so anyone have any ideas?

thanks

 

best spring u dont want it to jerk to bad pink one

 

can someone compare the Polaris X spring with the EPI pink? Does the Polaris spring have a higher engagement?
