Center bearing mount

[skaggs]

With a 2 piece shaft, where do you mount the center bearing?? Should it be on the straight line between the diff and the motor, or should you keep one section as an extension of the diff flange with 0 degrees angle, and let the front section carry all the angles? This is with a bike engine and a solid mounted IRS diff.

Why not play with the engine/rear end angles so you only need a single piece driveshaft?

Unless I totally misunderstand why you need a two piece.

Hello Skaggs,

 

Zero if possible for everything (perfectly lined up). If not, split the differences between all the joints to minimize and equalize all the joints. It is also ok to have one section zero on either end if the other shaft angles are 1.5 or less and equal.

A bike motor will have a very long driveshaft that can have wiping problems at high rpm depending also on the tubing od.
