G'day all. The other day while riding with my old man, this occurred two days in a row.
After about 50k's of riding, the bike would start to fire on 2 cylinders only. It was a very distinctive sound. This was accompanied by a dramatic loss of power.
The first day it happened, after pulling over and playing with the throttle a bit, I switched it off and back on again after a short pause. Problem was remedied all the way home.
The second day it wouldn't fix the same way. Intermittently, getting the revs up to about 7k whilst riding all 4 cylinders would start to fire again but if the revs dropped down to ~idle-ish then it would drop back to 2 cylinders. Also, at one stage in first gear, the bike started jerking horribly, almost as if it was trying to stall but because I was still rolling it was also bump starting itself concurrently for 5 seconds or so before just cruising on 2 cylinders again.
Has anyone experienced anything like this before? At the end of the day, my first stop next week is to drop it off to BMW but I just thought I would start the conversation anyway. It could just be as simple as a spark plug problem but I find it odd that it would fire normally once the revs got up a bit. I'll keep you posted with what the mechanics say.
Cheers, Will
