What are JL Paralever Bushings???

A guy in the midwest came up with a redesign of the Paralever
bearings from BMW. In his words:

"Thank you for your interest the Final Drive Pivot Bushings for the BMW
Paralever Swingarm. I developed these after purchasing a ' 93 R100GSPD and
hearing stories about Drive Shaft failures. I decided to inspect the Drive Shaft
every 2500 miles. The one recurring failure I found was the Final Drive Pivot
Bearings, anything from rough bearings to one set actually seized up from
shattered rollers. All lubing and preload was per BMW specs.. I will say the
bike is not stock and goes where I point it. To my knowledge a roller bearing
is designed to roll not rock back and forth, wearing a groove in the race and
a flat on the roller. My Bushings are a direct replacement made from 660
Oilite Bronze that is oil impregnated and self lubricating, matched to a Timken
Bearing race. They provide a Much Larger contact surface than the rollers
since the Full Face of the Bushing contacts the race. I have developed and tested
these for three years in my GS with great success, the present set has 15k
miles with no measurable wear. If any wear does occur it will be negated when
adjusting preload. I have also installed a set in my ' 94 K1100LT. These
Bushings fit ALL Paralever Final Drive Pivots ' 87 to present. I am confident
these Bushings are a one time investment and you will be happy with their
performance. "
The best feature about them besides the reliability, is the ease of refitting the Paralever

assembly after any servicing. On the road this could prevent a trip-stopping failure of the
OEM tapered needle bearings.

The bushings come with races to replace the existing races. Removing the old races is easy, you just drive them out from the inside. To install, remove the rear drive. The bushings are installed in the rear drive housing. For $129 you get two tapered oilite bushings mated to two races. Lube the races with Guard Dog Moly Lubricant.
