New clutch weights & blue/pink spring in primary, new cleaned belt set to the right deflection, new top end, new reeds, put stock can back on. I cannot pull proper rpm on my 13 pro. If the track is completely trenching it gets like 7800 rpm maybe. If i start wheeling I can get it to kiss 8050. I was just informed about the motor mounts getting weak in the Axys chassis and robbing RPM, is that an issue on the Pro chassis as well?

tbh I don't really know how the secondary even really works, would a rebuild or just a new helix help? Not having 8150rpm sucks....

Easy answer is to just drop 2 grams of primary clutch weight.

thats a band aid fix, im already running the 62s which is good for 6000-8000 feet, and a guy probably doesnt do much above 6500 in Vale and Mcbride

That stiff primary spring isn't helping. Go to a 120/320 primary spring and increase your secondary spring to a 140/240. Your most likely not getting passed the 56 degree first angle on your helix.

Did it pull top rpm before? If so then look at motor mounts if not then clutch changes are probably required.
