Re: R51/3 Fix or repair for sticking carb slide in throttle body

I have had this happen with motorcycles that were not run in some time and I needed to free up the slides. Here is what I have done with very good results: 1) Do not force the slides out as it will score the surfaces. 2) Spray wd40 in the bore and let soak overnight. 3) Pull the slides out, if you n...

Re: Should 1967 R69S have low or high shouldered rims?

The /2 models were available in both Aluminum and Steel rims. It was up to the dealer and/or buyer to choose. There were years the Steel were advertised and others the Aluminum was advertised as stock.

So, both are good to go.

Re: throttle

They only made 1 cam. You need to make sure it is timed right, your cam might not be timed correctly! The line on the cam needs to be lined up with the little arrow on the throttle perch. I just happened to have one handy and took a picture. Notice the line is lined up with arrow and is in the middl...

Re: Suggestion's for R69s tires

Kurt, I just read the service bulletins and it is very questionable on why they made the change. One bulletin says they are for sidecar and the other says it's for "higher speed". Read the bulletins below. See: https://vintagebmw.org/library_data/249.pdf https://vintagebmw.org/library_data/261.pdf h...

Re: Suggestion's for R69s tires

Kurt, Great question and one I ask myself as well. All I know is that when I was new at vintage BMW's, I put a mixed set on my 1966 R 50/2 (3.5 front and 4.0 rear) and the motorcycle was horrible handling. I replaced the rear and it was day and night. I am not alone in having this happen either. As ...

Re: Suggestion's for R69s tires

Same size front and rear is a must. Heidenau K34 or K36.

Re: R69s or r50/2?

The R 69 S is far more collectable and the re-sale value will always be greater. As stated earlier, the R 69 S is also much more fun to ride (I have both an R 50/2 and R 69 S) and can tell you the R 69 S is more fun.

I hope those help in some way!
