    My Experience in throwing a Hemi Predator on a CT200u

    Just thought I would throw out a couple of tips as I am nearing completion on this project. 1) Use the tins off the Hisun motor, you need the indentation under the cylinder/piston to fit the jackshaft setup. 2) Grab 4- 5/8"x36tpi-3/4" bolts and lockwashers to fit the jackshaft plate back to...
