3" belt kit F*ST90-06 kickstart spline

BDL kits do not have the gyroscopic imbalance and belt whipping found in some 3" belt drives. BDL has put the inner hub a full inch further inboard than most other belt drives. With the rear pulley further over the main shaft virtually all instability in the primary drive is eliminated. Kit include 8mm drive with BDL clutch, all mounting components, and BDL's new quiet clutch.
