It causes it to hit the limiter and cut out just on the on off stab of the throttle. If I am slower with the stab, its fine. 2014 pro rmk 163 with silber external, stock gearing, 7lb spring 9-10000 foot elevation, 91 pump with a splash of av. I have 72 gram rooster weights with the weight spread 5grams in the heal 2 in the middle 42-46 helix, pink primary spring and black green secondary spring that came with the kit Runs great otherwise with the latest flash. I cant add an more weight to the heal without going to the those heavy 3.5g washers Corey had me check my belt which is good. Running 8200 rpm. Clutches dont have any noticable belt marks on them. Was thinking of trying the black purple secondary spring or a steeper intial helix angle. Anybody have any other ideas to try?
