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 photographs.


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!

New Production! /2 Weld-on centerstand mounting tabs, left and right!

Are both wheels still on the ground when you centerstand the bike? Is the bike falling over on anything but level ground? Don't cut up an old frame! New production centerstand mounts are now available!

Upgrade starter motors for BMW, 1970-1976 (8 tooth) and 1977-1995 (9 tooth)

12 41 1 357 500R - Nippondenso replacement/upgrade starter 8 tooth, 1970-1976
12 41 2 306 700R - Nippondenso replacement/upgrade starter 9 tooth, 1977-1995
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. Sturdy, rebuildable and with no glued-in magnets, they have half the weight of the original starters. No rewiring or modifications are required.

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? Read more.
