Hello,

Well I have bit the bullet and just brought a nice fuel injected k75 engine, gearbox, 99% of the wiring and swingarm for a good price I think.

Anyway, Can anyone tell me where I may get a good clear wiring diagram and workshop manual.

Also can you tell me if the K75 is fly by wire (doubtful) or has a throttle cable ?

I don't think bmw still sell the paper copies of the wiring diagram, if they ever did, but there is a CD with a lot of models on it, that includes the K75.

Part number is 06727694500 for a little over $50.00. I was just discussing that with someone who bought same CD for the later bikes, there may be a few issues with using/printing due to their propriatory software.

There are quite a few Haynes manuals available for download online such as these:

The SLP 1 (BMW software) will print out the base wiring diagram on 3 pages. Readable with a magnifying glass. The nice thing about it is that it shows terminal numbers for relays and pinout numbers for stuff like the instrument cluster, L-Jetronic, etc...

I found a BMW K100 wiring diagram folded up in a K100 owners manual I've got. Not sure if it was ever available to the public or came from a shop.

Throttle cable.

does anyone know what if any, the different part numbers are for the two control boxs are for the K75? I have been told one controls the fuelling (silver unit) and one controls the ignition ( black unit)

I have been offered two different (supposedly) units with this engine. As far as I can gather the engine is a 1987 k75

Correct.

Silver= L-Jetronic fuel control unit

Black= Ignition control unit (ICU)

It's very easy to tell if they're the right ones. The L-Jetronic says "3 Zylinder" on the red Bosch sticker and the ICU has "3 Zilnder" cast into the top of it. Same parts were used for all years.

Thanks for the replies.

You just get used to a certain way of things being done ie japanese way of wiring and then you decide to be a sucker and try a german wiring.

You should see my other little project
