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
