Motorcycle engine to driveshaft?

[Dreamweaver]

How is the connection made from a motorcycle engine to a driveshaft made? Ive searched the net and seen a coupler that appears to go on the trans output side but what allows for the movement of the rear end?

Some sort of slip joint?

The only one I have seen was a Lotus 7 replica, and was basically a pillow block to support the end and a sprocket adapter.

Might see if some of the kit makers show photos of the parts online.

I'm not sure I really understand your question though

You use a driveline adapter on the out put shaft of the motor, then a U-joint then a driveline, with a slip jt. then another U-jt. at the rear end. Check out Dwarf Car Racing, on the web.

Quaife makes some pieces for motorcycle engines in cars including a gearbox with reverse.

Here is one retailer that shows some of the units.

Dreamweaver,

If the engine is mounted sideways you can use an automotive U-joint. Any shop that build Legend Cars can help you out with the adapt that mounts the U-joint to the tranny output shaft.

you could use a motorcycle engine that is shaft drive ,i have seen some home made trikes built using a modified miata drive shaft and the miata rear end , cost effective and works nicely .

There are some quick Yamaha maxims that are already set up to run shaft drive. The water cooled maxim x series had the genesis engine (dual overhead cam, 5 valves per cylinder, 10,000 RPM redline) makes over 100 hp stock and responds well to 4 into 1 exhaust, carb re-jetting, or turbocharging. There are also big 1100cc versions that are a solid platform to build with.
