I have a 93 storm with psi modblaster pipes. I cant get it to turn the 8600rpm it needs. It calls for 55 gram weights, I put 53grams in and still no luck. it has all the updates done. could my primary spring be worn out. It is polaris blue, the secondary spring is also the blue one. It has a EPI helix 42-34. I have been hitting around 8000-8100rpm not enough to catch the hp. Could my jetting be to fat. My (pto-390) (cntr-400) (mag-390). My gearing is 23-37. PSI recommends 23-35. Has any body had any luck with them pipes, please email me [email protected]
thank you.
