Hi All,

I have a 2008, R1200GS with 75k km. I spent a fortune on trying to get the bike running correctly but with no luck so far. I am hesitant to spend more money on expensive parts until I have some certainty of what is causing my suffering.

I have just received the bike back from BMW where they did a major service, within 100m of leaving the workshop a symptom appeared..

The are 2 x major issues are as follows:

1. After slowing down using compression braking, when pulling in the clutch the engine dies. It does not do this every time but probably 3-4 times per trip. Quite a dangerous situation, especially when navigating traffic.

2. The second issue is surging (or could even be described as a miss) between 4000-6000rpm range. The bike really labours to get through the 4000-6000rpm range and then seems to rev smoothly to the redline (although a little slower than a remember it doing previously).

As mentioned, it has  come back from a major service from the BMW dealer, the injectors have been checked, all the throttle bodies, valves, potentiometer etc have been checked and appear to be fine. Apparently compression is also good. The only other things I can think of is a faulty stick coil or Lambda sensor? Both are extremely expensive to replace without any certainty they are the issue.

If anyone has some ideas or suggestions, they would be greatly  appreciated! I am JHB based.

Thanks for your help.

Regards,

Craig
