I don't remember who sent me this PDF of an Owner's Manual, so cannot give credit to him. I have made some notes in this manual, all are in a yellow box like this one.

I suggest you do not use this diagram, but use the ones from BMW that are on my website, http://bmwmotorcycletech.infoThe BMW diagram, poor, originally in this booklet (someone added this colored one) is at page 84. My website has FAR better diagrams

BMW has used, depending on year and model, both orange and red for the oil pressure lamp. BMW also moved the oil lamp to the second from the top, instead of second from bottom

BMW has had several types of switch gear, and in the early years of transitioning to the /6 series, any of THREE types could be installed, so yours may vary, and in the USA you may not have the 3 position switch in the left sketch at all.

BMW's advice here for position 1 of the damper is OK, but if you have the steering adjusted properly, which is a bit tighter than BMW advises later herein, you should use position 0, and 1 and 2 for very loose and rocky-pebbly roads or roads with distinct rain grooves.

Wheel bearing service is tricky on these models, so see my website:http://bmwmotorcycletech.info.The wheel hubs MUST BE HEATED for servicing of the bearings.

Get appropriate taper tip for the grease gun you own by visiting an autoparts store, or, a store that sells/services chainsaws.

clutch lever has a nylon bushing, and it must be replaced if lever moves UP and DOWN considerably. OTHERWISE the cable can be CUT by the SLOT.

NEVER lift spark plug caps off a running engine. Use SHORTING adapters. BMW is wrong here.ALSO, I recommend that the idle rpm speed after full warmup be 900 to 1025 rpm for best carburetor operation and best oiling of the timing chain and sprockets.

Sticky Note
Information on synchronizing carburetors is on my website, and it is available there in two types, one for shorting the spark plugs method and the other is for vacuum gauge method. Use a higher rpm than BMW says, perhaps 900-1025 rpm for idle AFTER FULL WARMUP, which means AFTER A 10 MILE MINIMUM RIDE.

NEVER, EVER, lift the spark plug caps while engine is running. To shut off one cylinder, do NOT lift the cap, but use shorting adaptors!!!

Never, EVER, lift the spark plug caps. Use shorting adaptors!! Adjust for equal SOUND, shorting first one, then the other.

Sticky Note
NEVER, EVER use grease on the spark plug threads. If you wish, use a commercial antiseize paste, sparingly, and reduce torque 1/4th to 1/3. NEVER EVER re-gap a spark plug after it has been run even once..the metal can break, damaging the engine.

The F timing is much more important than the S, so set the timing for the F dot, after you adjust the points gap.3000+ rpm.

Rear wheel can be more easily removed if you remove front wheel, strap crossover to center stand securely, and let the front end fully down to the tarmac

problems with starting are often closed-up points or tightened valve clearances.

do not use these low tire pressures with modern tires. I suggest F33 to 36; R37-42
