My redrive is a series 3 drive and is the

unit. Rotax has the opportunity to use a considerable development budget
to tune their redrive for their engines and just in the last year or so
developed the slipper clutch for the 912S engine.

Rotax developed the slipper clutch for the 912ULS primarily because we were
having a hard time starting the engines. Once started, they ran fine.
The reason for the startup problem was the increased compression which shook
the engine on initial startup. This aggravated the float bowls on the carbs
by aerating the fuel. From their things snowballed and the engine stayed in
a "gear chatter" mode.
The slip clutch took care of this problem, along with a high torque starter.
Turned the high compression 912ULS into a kitten.
The 912UL has no requirement for the slipper clutch. Don't know about the
914.
Basic 912 gear box is same as 1989 models.
