i have the qpd set up on my bonnivlle america and dearly love it. my ba has big bore kit ported heads 3 angle valve job flat slide makuni. FAST 80+ hp at the rear wheel. that was on a dyno not an estimate. the belt drive is the best add to my bike i have done, Quiet smoth and cool. i would put one on my tiger BUT i think the angles are all wrong. you would have to have a hudge rear sprocket or maybe an idler. if someone makes one that works i will get one
