Re: R26 Schorsch Meier seat placement

The gasket you speak of is 46 54 5 096 109 It does not show it used between the shock tower flanges and the fender, however. If you are going to install a bench seat, expect the paint to get scraped off on both sides of the fender when you put it on. The only way to avoid this, is to remove the back...

Re: Engine slows

Another possibility is that when the clutch is squeezed, the pressure is pushing the crankshaft forward. Obviously, that is not good. To check, pull the front cover, and then start the bike, and let it warm up. Then shut it down, and place a fingertip on the generator armature and the generator fiel...

Re: Plunger rear suspension unit disassembly

On Huggetts site, www.bmwbike.com, while the drawings are sometimes generic (meaning one drawing for lets say, the R25, R25/2 and R25/3, when you click on a specific model, say the R25/3, and then the drawing and accompanying parts list for that drawing and that specific model only the parts in that...

Re: Only modern tires from now on....

I agree, that the Avon Road riders do make the bike handle better. I have them on my R50S, and it feels better when you encounter rain groves than the vintage tread patterns.

Re: EARLES VS US FORK

Another thing that no one mentioned, but is quite significant when it comes to telescopic vs the Earles Fork. With any telescopic front end, when you hit the brakes hard, the front end dives and the weight of the bike transfers forward, and the length from center line of axles front to rear becomes ...

Re: R51/3 center stand refurbishment

Take the center stand off completely. Set it aside. You weld the heavy wall tube between the ears of the FRAME not the center stand. You need not worry about the elongated holes in the ears of the FRAME. The tube will support the pin full length across the ears on the FRAME. You must take care to ge...

Re: R51/3 center stand refurbishment

A good, permanent fix, is to find a piece of heavy wall steel tubing, that the center stand pin slips nicely in, and cut it to the correct length, and WELD the tube, between the two center stand ears on the frame. This will support the pin full length, and you will never have any problems ever again...

Re: R69 ignition retard lever / correct magneto

Let me explain why and what the purpose of the lever is. For starters, it is a RETARD lever. The arrangement was used on the R68 and R69. It was used because the R68 and R69 were high compression engines and in many countries, that the bikes were exported or ridden into, gasoline was very poor, and ...

Re: R26 Kick Start Spring Replacement

There is no "easy" way to do it. Clamp the shaft of the segment gear in the jaws of a vice with copper vice jaws, so you do not mar the shaft. clamp it tight. using vice grips, get the straight shank of the spring in the hole of the shaft. Then using screwdrivers, lever the hooked end over...
