From an early /2 thru R1200 series and K bikes we are able to update and repair your transmission and final drive. We can check and rebuild your transmission, update internal components, and undercut gears in certain M series transmissions. From $350.
We use only top quality NTN, Koyo, or Timkin Bearings. We will not use cheap bearings. We also solve known problems by modifying or changing a bearing to a higher grade improving the design which creates a transmission that will last a long time. Don't be fooled by a cheap rebuild.
What exactly is undercutting the R1100 Transmission gears?
The transmission gears lock together with a series of "dogs' or "dogs and slots". Under use, the gears can begin to separate until the dogs become disengaged, this causes the transmission to jump out of gear. UndrU 
Now notice in the above photo the dogs that are in the circle. They both have angles cut on them where they meet. This causes them to lock together. They cannot separate without first backing up to unload the angles. This is an undercut.
Undercutting the 2nd and 3rd, 4th and 5th gear prevents the fork wear and gear slipping that plagues certain R1100 M series transmissions. A careful rebuild works well with gear undercutting.
Transmissions: Rebuilds, upgrades and repairs to /2, /5, /6 and /7, Airheads thru 1995, R1100/1150 Series, and K Series. Prices upon request.
Final drives can be cleaned, resealed, rebuilt, splines rebuilt along with the wheel drive splines. /5 motorcycle splines are rebuilt to /6 standard which have a 30% better surface and last a very long time. We also recommend the JL Paralever bearing replacement kit for Paralever Final Drives.
Final Drive: Rebuilds, repairs and spline repair can be done. Prices upon request.
Carburators for all models including 
Dellorto and throttle bodied K and R models are cleaned and rebuilt. We also can clean and rebuild fuel rails on K bikes with new fuel injectors. We use high quality rebuilt and cleaned-tested fuel injectors with new O ring seals ready to be installed on the motorcycle.
Engines dis-assembled, cleaned, repaired, rebuilt and re-assembled.
Wheels can be rebuilt for your BMW with new bearings, new internal "stack" and new drive splines.
Tanks can be cleaned, prepped and relined making them last a very long time.
Electrics: We can clean all starters, update electrical systems and supply you with any electrical part, electronic ignition system for the early BMW motorcycles and Omega charging systems-see our electrical page.
Paint: We can help you restore your BMW to original paint specification. We do not do custom paint jobs. This web site has all the BMW original paint color codes. Find yours and then we'll get the job done. http://www.bmbikes.co.uk/paintcodes.htm
