A little over 3 weeks ago I took my GSA in for its 12 month/12000 mile service. I also asked them to investigate some vibration at high-ish speeds (i.e. around 90mph the instrument cluster was shaking around and vibration could be felt by both rider and passenger). I told them I felt the likely cause was a recently fitted new rear tyre.
They did the service (and also found the rear brake seized - which they were able to free off, although I had to spring for a new set of pads), balanced the front wheel, and discovered that the paint/coating was flaking off the rocker covers and the metal underneath was corroding. They recommended it be booked in for further investigation of the vibration and for the rocker covers to be replaced. On riding the bike home I immediately noticed a distinct misfire/hesitation at low revs, especially when going from throttle closed to small throttle opening. It was especially noticeable when negotiating e.g. roundabouts - It would splutter and fluff as I began to open he throttle, then suddenly surge away as it started to run cleanly. Not the desired effect on greasy roads... The vibration was also still apparent.
So three weeks ago I took it back in. During the course of the first week, they faffed around rebalancing the front wheel, turning the tyre 180 degrees and not achieving much. They also tried a complete wheel + tyre from another bike and the vibration was still there. They also rechecked all the valve clearances, throttle synch etc and fitted a second set of spark plugs. Still the rough low speed running persisted. They needed to spend a bit more time on it, and as I was a bit dischuffed with the G650 loan bike, I went back and secured the use of a K1300S HP instead, which was much more fun
Week 2 passed, and lo! They discovered that if they swapped out the rear wheel the vibration went away. Quelle surprise! One rebalance of the rear wheel later, and the vibration has allegedly been banished. Great. The rough running also appears to have been fixed after they zeroed all he "learned" parameters in the computer. But then the bad news - during final pad testing, they discovered that the clutch is slipping. New clutch ordered, so I'll just have to slum it with the K13 for a bit longer ;-)
That was just over a week ago. Today I phoned to enquire when my bike would be ready, to be told that it was just about to go onto the ramp for the clutch work. So that'll be another week with only 175bhp to play with on the way to work...
I'm desperately trying not to lose faith, but I'm beginning to feel a premature end to my BMW experience is increasingly likely :-(
