Just called RCR and Hpd toget the rpms of thier pipes and clutch kits.Rick said with his topend pipe to make the shift out occur at 6900 to >7000rpm. Hpd said thier clutch kit shifts out at 6800 rpm. Is this enough to cause performance loss on the sport.The kit has red and yellow primary with 58 g wieghts and a violet secondary.How can I bump the shift up another 150 rpms?Thanks.

 

Just putting it back up top.

 

[img]i/expressions/face-icon-small-happy.gif[/img] hey biggin, move up to the plain red polaris spring. It is slightly higher on the rates and will probably do what you want. Without changing the weights, that's about all you can do. Polaris does make a 57.5 gram weight, but it would have to be special ordered for you.Bubba
