Consider adjustable weights. Then with that track I'd run a bit less helix. Like a 58-51 or 57-50, something in that area. Red spring, hole three or four, and more primary. Like a 160-260 or 160-290. How was it running before?

thanks for the help, I am def a clutching newb, just want to maximize my setup.. It was running ok before, i was happy with the pull down low, but it didnt have much top end which is ok with me, seemed to max out.. the setup i was running was a sugg. from before i went 136.. But i have been having primary issues for a couple seasons now, bushing on moveable sheave went and clutch would get stuck at times, even when weights were good, now i have a brand new primary and weight look vry worn where rollers ride, so i dont want to put them in the new clutch and ruin that..

74-75g anythings. Touch them to a grinder or belt sander if you need more rpms down the road.
