Re: professional /2 engine rebuild

We know that all inventory for Bench Mark Works was taken over by Max BMW. I will let Vech speak to their abilities to overhaul a /2 engine. From my '69 R69S, I "dragged" the engine minus the outside stuff to Dave Clark's shop in Pacific, MO. His shop is Endeavor BMW. Dave cut his teeth on /2 bikes ...

Re: R50/2 149-150 Carbs fouling plugs, put 105's in and seems fine...but is it?

What year is your bike? I'm not totally familiar with NGK notations, but the "E" indicates it is a long reach or 3/4"...is that correct for the bike? Early in production the reach was 1/2". I just want to be sure that your plugs are sticking into the chamber correctly. Also, does the "D" mean it is ...

What plugs are you using? Also, how is the timing? Do you have differential timing? If there is a big difference in timing, one side could be firing advanced, the other could be firing retarded. Maybe I'm missing something, but fouling plugs is usually too rich. Bigger mains and raising the needle w...

Re: 1959 R 50 - bar end signals

Welcome to the forum! I would say not on the 1959 models but await other input. The 1959 and 1960 BMW brochures don't show any models with bar end signals. The 1961 brochure does show bar end signals. A BMW service bulletin titled "Subsequent installation of a turn signal...into single and twin cyli...

Yup! That's how I wore out the clutch bearing on my Firebird early on. I changed my habits after that!!

Re: thrust rod broken

Yes, splash oil from inside the transmission is supposed to oil everything aft of the felt. The felt seal is there to keep the oil from running forward and getting on the clutch. I don't think this is the model bike, but I recall a situation where the pieces didn't fit inside the tunnel well and/or ...

Re: '85 R80 RT won't start

Since you have one of the later ignition systems with a Hall effect sensor, I wonder if you might have an issue with. When you mentioned the kill switch toggle caused a spark, that pointed me to Snowbum's site. This is a lengthy article, but he mentions the issue with sparking when the kill switch i...

Re: thrust rod broken

Maybe it was just a defect in the rod? Maybe the alignment of the transmission on the studs wasn't the best. Also, be sure that the forward end of the pushrod has a good tacky grease on it where it rests on the pressure plate. That must be able to spin when the clutch is actuated and the rod is push...

Re: Paint codes

As far as I understand, Holt is no longer doing any painting. Check out their website.

Re: Timing problem – centrifugal advance unit worn out?

The bike starts fairly well for others, but is reluctant to start for me. That sounds like a technique issue with what you're doing. You could figure out what they are doing that is different than you. My guess is the issue is with the advance unit. The flywheel is solid and doesn't move around. It...
