2000 1150GS Rough Running

[WayneC]

Whether there is resistance in the lead will depend on whether a resistive spark plug is used

On the 650GS single spark BMW use 2 x 1000 ohm resistors, one in the plug cap and one in the coil connector and a non resistive plug

The LHS cable reading of 5k ohms may be about correct while the RHS is clearly cactus, I would be surprised if BMW used anything above 5K ohms

Thanks Wayne.
I will order new set of leads as soon as shops open. In fact I will order ex USA tonight. Found a set for US$55 from Euromotoelectrics.

I have just done a side stand switch test with the MM. I get 0 Ohms with stand down only on one pin. The Yellow( white on my wiring) /Red combo gives no return at all but the Red / Brown does.
This is without taking the switch of the side-stand as I am without circlip pliers currently and that is the smallest circlip I have ever found on a bike.
I will read up on how to by-pass the switch in the interim.

The Red/Brown is likely the earth return wire as brown is normally earth on all BMW's and the stripe indicates which circuit it is associated with

The bypass is likely to be Brown/Red to one of the other wires, on the 650GS you can join all 3 wires safely for the bypass

For R1150 and R1200 sidestand bypass have a look at:

Long winded document with butchery as their method, would not touch their methods with a barge pole, the simple way of doing it is to make a wire loop with pins to fit the sockets or even go to the car divisions and get the pins and socket bodies, on the 650GS you can use 1/8" spade connectors and I gather a fair proportion of the other models either use the same plugs/sockets or similar ones on which 1/8" spade will work

Hi Wayne and Jughead,

Decided to change out the plug leads, HES and will look to replace the coil should I still have issues. I haven't discounted the stand switch at this stage but don't really want to cut the wiring. I will look to somehow fit connectors should it not prove to be problematic.
I will report back after my son returns from holiday to help me sort it. Peter.

Be aware that the side stand switch/harness/socket with the red/white/brown wires is a generic item used on many models and on the 650GS the red and white wires can be reversed on some supplied to BMW, it seems to be just the way different batches were made so some 650GS owners have had to loop red to Brown and others White to Brown, I would not be surprised if the 1150 was the same

OK.........
My son swung by on his way home from his summer break and confirmed that the one lead is definitely AWOL and the terminals in the plug that attaches to the coil is kaput. I could not pull it apart and elected to wait for my son who applied a lot of pressure before it pulled apart. One spade terminal had corroded away and the other was on its way out. This is not a water-proof plug so any moisture is going to enter down the wires to the spade terminals. I will need to two order these two spade terminals that fit into the plug ( part #1459615).
Chances of the local BMW shop having these is slim. Are these by any chance also a BMW car part?? Peter.

Use realOEM to do a Part No Application Search, it will tell you what models (car/bike) a part is used on

While I am not familiar with the plug caps/leads on your model I can tell you that in all the years i have owned BMs I have never purchased BMW plug leads or caps, I have always purchased after market parts and mostly made up my own leads which is what I have on my Dakar, much better than BMW

Cheers Wayne, will look it up. Peter

Thanks everybody for your help. Bike started first push of the starter after replacing the plug leads ( got a set from Euromotoelectrics for $55) and replacing the two small metal bullet connectors in the plug that connects to the coil. Local auto-electrical store gave me the four bullet connectors for free. Went for a one hour ride and all seems well.
I have a new HES on it's way from Cata Dan which I will also install as soon as it arrives. Peter.

Pleased to hear you have it sorted
