Plunger frame restoration book!
|book004 -- BMW R51/3-R68 "Motorcycle Restoration and Service Manual," by Chris Betjemann|
|This new restoration and service manual is the most comprehensive study of the BMW R51/3 through the coveted R68 models ever written.|
The amount of changes during the 5 year production of these machines is astounding. It was if BMW could never quite decide what was best, and made many rapid changes in that 5 years. To all you vintage buffs out there, did you know that:
Six different frame variations
Three different petcocks used and each one has the technical drawing in the book!
Two different headlight shells with different main switches
Two different forks with two variants of each and two different steering dampers.
Two different wheel half hubs and three different full hub designs.
Four different steel wheel rims
Two different aluminum wheel rims
Three different generators
Six different air cleaners
Multiple headers and mufflers
Twelve different forward flywheel sections
Three different transmissions
Three different transmission output flanges
Three different variations of Eber tail lights
Five different variations of front fenders
Ten different variations of rear fenders
Fourteen different variations of speedometers
All of this is covered in the book, plus more!
Not only is all this historical material present, but step by step procedures
for completely disassembling and re assembling the entire machine with photos of
special tools that are required.
The manual consists of 582 pages, with seventy original line drawings, and 570
New production suspension bands!
|S 103 Z 46--side car body suspension band for LS200 S250 TR500|
This is NOT the European molded, one piece incorrect suspension band. We had these reproduced from an original, and is manufactured in the same manner as the original, being constructed by using one long wound rubber strip, and the layers bonded together. These are of the correct dimensions, elastic, and very strong! And cheaper than the worthless European ones that prematurely break!

These drop-in starter motors, originally for Toyota trucks, are mated to a new case and drive gear for BMW engines. An improved design allows approximately 30% to 35% less amperage to operate.

|The Importance of Clean BMW Oil Slingers by Craig Vechorik
It is very important, when you acquire your restoration project, to tear your
engine down, and clean the oil slingers.
You have two choices here:
1) buy the tools, a torch, a book, and learn to do it
for yourself, or
2) farm out the project someone who has both the tools and the skill. Either way, it
's important to get it done.
Why is it so important?
