BMW riders from around the country and beyond send components to Virginia Motorrad for repair. Transmissions, final drives, engines, water pumps, we see it all. For technical articles on these components, look at Anton's website.
Transmissions: Airhead circlip grooves are cut on site. Gearing modifications are available for Airhead and some Oilhead transmissions. General overhaul and repair for all 1970 through present. Correction of 'skipping' problem or input shaft wear on 1994~2000 Oilheads. Stripped spline repair on 1150-style 6-speeds. Some custom gear ratios including hybrid Enduro transmissions with overdrive 6th.
Final drives: 1970 through present. Wheel spline repair on Twinshock Airheads; driveshaft spline repair on K75/K100. Bearing failures on some newer ones are due to incorrect shimming from the factory; every final drive gets set up properly from scratch. Pinion seal leaks fixed. Custom ratios can be installed. Nylatrol bushings to replace the marginal bearings that BMW used for the Paralever pivots.
K water pumps: Small job but someone has to do it; overhaul is about a quarter the cost of a new pump and is very reliable. The right tools aren't worth buying for you to just do the job once.
