    I had the chance to buy a Franken-Beemer over the winter for a pretty good price. This is my first motorcycle rebuild.

    The bike is a 1972 BMW R60/5 with a 1970 R75/5 engine. Frame is straight but every pc of chrome and steel is rusted. The bike had been sitting in a garage since 1994 with a full fuel tank. Amazingly having a full tank of old non-ethanol era fuel kept the tank and internals in good condition. With the exception of oxidation the engine is in pretty clean on the inside. As for everything else im going to need new rear shocks, wheel bearings, brakes, tires, seat, and anything plastic or rubber on the bike... it's going to be a fun project.

    After rebuilding the carbs twice (i missed the fact the first time around that the bowls did not match the 1970 Bing CV carbs) the bike starts up and runs. The idle is fast but I believe I can slow that down once i adjust the cables.

    Right now I'm looking for someone who can rebuild a speedo and tach. I also have shorts in both handlebar switches as well as the front brake lever.

    Get new tires first, before you are tempted to take it up to speed. The high idle could just be a sticking advance unit, remove, clean, lubricate with special grease and replace. It probably needs it anyway. There are currently reproduction speedometers available for about what you'll pay for someone to "maybe" fix yours right...

    This. Wirespokes restored mine to as-new condition quickly and for a very reasonable price. Highly recommended!

    Tires and shocks are on the list to be changed before it leaves the driveway.

    I'll take a look at the advance. Thanks

    Got the PM!

    As for the reproductions - I haven't seen one for the /5. The one for the R80G/S didn't impress me - more than just the absence of a trip meter.

    If this bike hasn't been driven yet how do you know the instruments don't work? :lol3

    No fuses on a /5 I guess, I don't know. But you can check the wiring and the cables for the speedo and the tach. Actually I guess if the rear wheel is off the ground on the center stand and if not put some blocks of wood under the stand then the spedo can be checked.

    Has the idle come down yet with cleaning the advance unit?

    ^ late /5s do have a couple of fuses in the headlight bucket. I think the break was at the same time they went to the LWB, but I'm not sure. I doubt that a 72 has fuses, but it's easy to find out.Mine is a 71 and it does not have fuses. When I got mine, it was not running because the entire wiring harness was fried, because it didn't have fuses.

    Mine is a 1973 R60/5 and also has two fuses in the headlight. They are the two blocky/tubular things located at about 5 o'clock in this photo:
