I found an OCC stingray on the side of the road and refurnished it. I am now at the point where I want to start the buy list to put a motor in it. At first I was thing 4 stroke but I’m not sure it will fit. I see a bunch of builds on this forum and want some advise. Can I keep the rear brakes? What is a cheap front brake alternative? Chain tensioner mounting? I don’t want to drill the frame unless I have to. Sprocket tooth number? Is there a kit worthy of plug and play? I have access to a fab shop so I can make the mods where I need to.
