After reading Gunny's excellent report about the Fix sheave kit, I just had to have one for my 700 Grizz. I first installed the weight's that came with the kit, It seemed that I had to give more throttle to move the Grizz, not the low end response that I was looking for so I removed the weight's that came with the kit and installed the heavier stock weights, that did it I had instant response time. The Fix sheave kit does help! you may just have to play around with the weight's.- I do have a 735 BB installed and that may be why I needed the heavier weight's. ;;t;;
