So, I have a Piped 800 Axys. Works great up top, 5500-7000Ft, but when lower it over revs. I am a boondocker here in Revelstoke area. But lots of times, we are riding great trees in the sub 5500Ft elevation. Where, if I grab full throttle, she looses RPM. Not loading the pipe enough I think. Up top, she pulls great, no over rev and no "rah rah's" from the pipe. But also I have a pretty shallow helix, I feel. Presently, 66g series 10 weights, 120-330 spring. Helix is a 48 36 .36 I am 163 2.6 track, with Kurts gear down to 2.37. If I increse Helix angle a bit, will that lessen the lower elevation issues?
