A jackshaft is a shaft located away from the motor usually on the frame. It's
used mainly because the sprocket on the engine will not line up on the sprocket on the driveshaft or axle. The difference between them is that the jask shaft causes a loss in power and more risk of misalignment or something breaking due to power and torque. With a chain you have direct connection where its straight power right to the axles.

So a jackshaft loses torque and pwr becuase it does not take
advantange of the different size sprockets like a chain can?

Does the motor have to be mounted sideways to install a jackshaft on
it? I think I'm getting it?

The jackshaft run paralle with the axle shaft. You gain torque to the
wheels but with lose speed/rmp. Just like on a bike small gear on the
front big one on the back/axle.

A jack shaft power loss is very minimal. The jack shaft is parallel
to the axle and engine shaft. You run a drive, chain, belt, whatever,
from the engine to the jack shaft then from the jack shaft to the axle.
All the sprockets can be the same size, different size, or in pairs,
depending on what you want your total reduction ratio to be. The
advantages are that you can have the drive from the jack shaft to the
axle on the opposite side of where the engine shaft by have a jack
shaft long enough to reach that far. In other words, if your engine
shaft is on the left of the cart, you can use a jack shaft and drive
the axle on the right side of the cart.

It loses torque and power due to having to run a chain from the engine to the jackshaft and then to the axles. no the motor is still mounted normal in your frame. the jack shaft is mounted behind the motor on the frame.

So basically it is a shaft with two sprockets...one for the chain from the engine and one for the chain to the main shaft?

Drag bikes use them to help the chain clear extra wide rear tires. I've seen them on choppers with the 300 series tires too.
