Just curious if anyone has ever tried mounting a "pocket bike" transmission to an engine on a minibike to be used in place of a torque converter or jack shaft?
Also, I had an idea involving a lawn tractor gearbox. (Doubt it would work, but I had to share). I have "access" (gotta go dig it up some, it sunk in the mud, haha) to a "small" vintage lawn tractor gearbox. It's a Tecumseh/Peerless 1200, 3-speed w/ reverse in the H-pattern. I think it had been attached to a small Ford lawn tractor at one time.
I began to think about how I could cut off some of the axle shaft length, leaving the gearbox (gotta figure out how to seal the ends though), and use it as a pseudo-jackshaft. I thought about how if I did something like this, I could run power from the minibike engine to the input shaft on the gearbox, and then from the gearbox, through one of the axle shafts to the rear sprocket. My logic is that I would be able to have different gear ratios at hand for different applications, whether it be on the road or going down through the woods/swamp, where I would be prone to wanting to crawl along without burning up my centrifugal clutch. I think the input shaft is on the side instead of the top, so it could possibly work for a horizontal shaft engine setup.
I still have to measure it to see if it fit in the first place though.
