Howdy,

I am venturing into my first Predator 212 (removed gov.) build and wanted people's opinion on somethings. To start with I am using a Schwinn OCC Stingray bicycle that I will be extending the frame. On the main lower frame bar I will be using 2”x4” square tubing so that I can also use it for the motor mount. This idea comes from how Crazyhorse does it, https://tinyurl.com/y6xqj2vh. The main issue is that I want to use a clutch with a jackshaft instead of a torque converter. I was hoping that someone could give me some insight into what clutch/clutch tooth, jackshaft in tooth, jackshaft out tooth, and final drive tooth I should use. Ideally I would want to cruise at 35-40 mph and be able to leave from a dead stop without hurting the motor or clutch. Extra info: Tire diameter is 22-23 inches, I weigh 200-210lbs and am 5’ 11”, and I do have a fabricator helping me. Any information anyone can give would be greatly appreciated.

*I know that there are other post about this out there but no one gives a straight answer.

I'll chip in with clutch suggestions. Centrf. "bully" clutch from Sportsman flyer, his setup is the berries for the 212 Predator if you want a manual clutch the 3-D motorsports is a good option. Both accept a 3/4" output shaft
