2003 K1200RS in back of my new 2007 R1200GS. I love them both.
Need more 1100R's here!
Okay, I'm only doing this just to get the thread back on the oilhead track....
New to me bike (in foreground), old bike to new owner (in background).
Cheers, Bill J
Great pic and the perfect color 4 a bike
IMHO hardly a better looking bike around, that's fer shure! LOL
Notice that you also owned a 750F (sohc) Honda....that was a long time ago and sort of a quantum leap to today. LOL
Cheers! Bill J
Yeah, it turns a lot of heads around here. Many bikers have never seen one before and think it's a sport bike because of the exhaust pipe exit location.
I have just over 10,000 miles (yeah I know that is pretty low), bought it used 3 years ago.
I had a strange thing happen with it. Last year after taking apart the rear drive and lubing the drive shaft splines, it seemed like the bike picked up a lot of vibration. I took it apart 2 times after that just to make sure I had put it together correctly. Still vibrated. I was at the end of my expertise and ended up taking it to the dealer.
After the dealer inspected my work on the rear drive, they were sure the rear drive was not the reason for the vibration. And besides, the vibration was more related to RPM. It was almost unrideable above 4000 RPM and would occur in any gear.
They fixed it by doing 2 things-
1. Their main theory was that the pistons and/or connecting rods were out of balance with each other. They said they had seen this occur before and not just on BMW's. They found that one piston weighed a lot more than the other, initially they thought it was mostly due to carbon build up. So the pistons were sent to a machine shop for balancing.
2. Balanced/synced the throttle bodies
So I got the bike back before the end of riding season last year, took it easy for a while like a break in period, and then started riding normal.
All I can say is that the excessive vibration above 4,000 RPM is gone and the bike just runs great. I hope that all that money I paid for the piston balancing was part of the solution, and not just the throttle body work.
I imagine some of the oil head experts on the forum will let me know if the piston balancing was a likely cause or not. I imagine piston balancing is something people that race motorcycles might do as part of an engine "blue-printing" step.
Just thought you might like to know in case you have the same symptoms.
