I was wondering what the best mountain setup would be for 8 - 10000 ft. Like Weights, Helix . Its an 06 crossfire 7(144). Last year I ran the recommend cat setup. 68 gram weights and the straight 36 deg helix. It seemed to do pretty good but bogged out on the top end on a long pull. Any ideas? I thought maybe it was getting too much fuel, so I got a injector perfector this year. Belt deflection was good. Any help would be appreciated. Thanks.
