Shaft drive bike motors

Looking at some parts online and started wondering why the shaft drive motorcycle motors aren't being used in midgets and or mini sprints. Could just hook up drive shaft like on the bike to a quick change. And the v4 motors are pretty inexpensive. Just kicking around ideas here so don't shoot me please.... Lol

In midgets the rules state that the rearend must be directly by the crankshaft no trans gear reductions etc.

True. Easy way to convert a midget to a mini sprint tho.

I've had the same thought, Pat; that's how the Dwarfs (Dwarves?) & Modlites do it.
Some Mini Sprint ass'ns don't allow V4's but a V-Max powered car running a driveshaft to a QC would be an interesting combo...
Don't shoot me either guys, just exercising the brain before work

UH, wouldn't that be then, a Kenyon Midget? Just sayin, about anything you can think of, has been done or tried, depends on the rule of the day! Bob

That's correct. I still have some of my old dwarf car stuff and I'm gonna play around with just moving the drivetrain over into a bare chassis I have. I have a 2000 Honda 1100xx still setup with the drive shaft setup so I figure what the heck. Might do a write up with pics because I was really easy to "bolt" the whole drivetrain together in my old car.

You might want to look at the rules, MMSA says driveline to be CENTERED in the chassis, and the engine can't hang out, if you'll notice, a Kenyon midget left end of the engine, is really hanging, so maybe it's a grandfather deal, with the newer engines using a stacked gearbox, rather than behind each other, does cut this distance down some, but I don't know if it's enough to meet the current rule or not, but better ck.!
