Bike Engine Sprocket Rotation...
Does it make any difference if a chain / belt is pulled over or pulled under a bike engines sprocket?
The only thing I can think of is there might be a bit more 'lash' if pulled under it (???).

Are you thinking of the engine being behind the driven axle?

Nope... I'm thinking of turning a shaft driven bike engine through 90 degrees and putting a sprocket on the counter-clockside rotating output
flange.

Aparently should be ok. Look near the bottom of the second page in this
PDF figure 2.

Of course the eagle-eyed amongst you will already have sussed that a counter-clockwise rotating output shaft is going to drive the rear wheel
backwards!!!
Doh!

Suppose that depends on front or rear wheel drive, you may have to turn the car around

The one problem I can see is that a shaft driven bike will not normally have the sideways forces applied that come from driving a chain. My bike has a
massive bearing just on the output shaft, that is designed to resist the chain forcing the shaft sideways. A shaft driven bike may not have the same
resistance and may quickly wear the bearing.

What shaft driven bike is it ? Some drive from the right and some from the left. If you take the shaft unit off and the gear you will not need to turn
the engine just fit a sprocket in it's place.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

It's a Triumph Rocket engine. A wee bit of an oddity as its mounted longitudinally.

The manufacturing process of the Rocket 3 is very interesting. Rocket 3

A friend of mine has one with a supercharger fitted. It will be good if he ever gets it running right.

I'm worried, I didn't notice what was going on until more than half way through...
