Those SjBMW clamps are a GREAT bang for the Buck! I've got one on my 87 mono

;) , hi to all :D . can anyone tell me what the size's are of the cylinder and cylinder head " nuts" ? . have to buy a torque wrench and socket to suit, have picked out the torque wrench which is a warren and brown # 321500 ( any comments on this ? )but not sure of what size socket i need...

All R65 bikes have an O-ring in the flywheel. It's the same as all other Flywheel O-rings, which started in mid 1975. The "heavy" clutch on the 79-80 R65 is not the same as the heavy clutch on the other bikes. It is used only on the R65 for 2 years, in 9/80, ALL BMWs got the new style clut...

All in all, I will attempt to keep Chinese Crap off of my German motorcycle whenever possible. It's more and more of a struggle every day.
Besides, 4 new bushings and a set of brushes and the old Bosch is like new again.

20 bucks is not that expensive for a factory part that under normal use, may go bad once in the life of bike. But that's just me.

An R90 top fits nicely onto an R75/5 bottom. (That's what I was riding when it went into the "wet-cat" mode.) I'd check the measurements for the block boring job and the cost...then consider if someone would make a swap if the numbers don't come out OK for you. We assume you have the push...

Yes MAttfish, you are incorrect . The starter the OP bought is one of cheap Chinese copies of a P.O.S. Valeo. The ad from EME states that it's better than the reduction drive Car starter. Rick at Motorad Elektrik is the one selling the re-configured Japanese gear reduction car starters. I for one, w...

The Valeo starters were/are made in France. When they first hit the streets and then started falling apart several years later, we at BMW dealers named them "the French Revenge" But I thought we LIBERATED them! Now, if they had only sold them in Germany... I was talking about Germany! BMW...

New from EME, an "airhead priced" gear reduction 8 tooth starter for 70 to 76 bikes. http://www.euromotoelectrics.com/EnDuralast_Starter_BMW_R_Airhead_8_Tooth_Drive_p/bmw-str1m.htm I just ordered one and will keep all updated on how it lasts. It's going on my winter /5 which gets ridden t...
