While were asking... Im running blue primary with s55s, violet sec. Ive heard that s58s will help the keep tires from breaking loose in dirt. Im rite on the money with the rpm's so I dont know. [img]i/expressions/face-icon-small-confused.gif[/img]

 

Sorry-- breaking loose out of the hole in dirt. thanx

 

Thanks for your time Bubba I wasn't sure with the red/yellow primary spring that the 55s weights would give enough side force to stop belt slipping.

 

Whitedog, if you want to gain .2 to .3 in 300ft and blaze out of the hole then ditch the blue primary and get the violet. The blue is a casual or trail riding spring. If you ride aggressively or drag race, then go with the violet. Wheelspin on those bikes wont hurt you. Because the belt drive comes on smoother than a clutch bike, you need as much stall speed and hit as possible for a good hard takeoff. I have seen the time gains many times from that change.

 

AAAHHHH! good good. Im gona order one tomorow along with my crank case saver. [img]i/expressions/face-icon-small-wink.gif[/img]
