Review: Works..... But barely worth the time - They were right most of the parts are garbage. The set screws stripped.... And I mean evey one of them. Spent quite a bit of time extracting those. I had to sand down the Jack shaft itself about 1/16" just to get them in the bearings. Also did quite a bit of filing just to get the plates to go on my motor. And all of the fasteners are not only garbage.... But are the wrong size all around. This doesn't even mention the absolute crap crankshaft. The chain ring and free gear are decent. But other that that... Be prepared to replace anything with threads in this kit.
