Hello all! Been having quite a time dealing with my girlfriend's R1200R and we've spent quite a bit of money on it with more problems just cropping up.
Currently, the bike gets very serious vibration at anything over 4000rpm. This happens both in gear and in neutral. Everything else about the bike is now functioning well and it rides great if you short shift and never get above 4k. The bike has 48,000 miles on it and I just did its major service. Everything went well and the engine is absolutely in sync (dealer worked hard on getting it perfect). In fact, at 4k RPM with my carb sync tool hooked up, it's dead even even though it's vibrating heavily.
So onto its history. Bike was purchased used at 36k miles by my girlfriend. She rode it for about 6k miles without any problems. After a while, she noticed an intermittent problem when in slow traffic where the bike would have a rough idle when pulling in the clutch and would occasionally stall. Diagnosing that problem went beyond my expertise and I took the bike in to our dealer who said the computer diagnosed a faulty throttle position sensor. It was replaced and that problem appears to be gone. However, at the same time, the dealer noticed oil seeping from the bell housing and surmised that there was a leak on the counter-balance shaft seal. We had them go ahead and fix it and they tore the bike down and found they were correct, so the seal was replaced along with the clutch assembly. Bike came back and immediately had problems with a really rough idle. Returned to the dealer and found that there was a tear in the intake boot on the left side (where they had worked on the TPS). So that was replaced and the throttle was carefully synced and the original problem is completely gone.
All we are left with now is this new vibration issue which did not exist before the bike went to the dealer. I am once again beyond my expertise in diagnostics and will probably be bringing the bike back in for them to look at. Since the clutch was just replaced, I wonder if something is misaligned or off balance with those components, however I'm not sure why it's not noticeable until 4k rpm.
I'm hoping someone out there has had similar symptoms or experience with them and has some advice.
Thanks in advance!
