I have a 2006 BMW K1200s with 50k+ miles. Transmission was replaced under warranty the first time around 15,000 miles in 2008. I was told it was probably replaced with an 08 transmission.
Fast forward to summer of 2019, transmission starts to kick out of second gear at high RPM's when giving it over 50% power. Took it to the dealer and they quoted me about $7k for parts, plus labor. The bike is not even worth that much. After reading the forums here, advrider.com, and the old kbike forum, I decided to tackle the jobs myself. Going to send the trans to Mark at R&D Motorsports in Clearwater, FL.
Got the transmission out last weekend. Took me maybe 4 hours getting it apart and taking many pictures.
Here's how she sits now.
Unfortunately when i removed the clutch cover, I found pieces of the timing chain rail have some how broken off the lower rail.
Now it looks like I'm going to have to take the valve cover off to replace the rail according to the BMW services DVD. This means I'll need to removed the radiator and get it filled again.
I have no idea how this broke and for how long its been broken. I had the big 12k services done in 2018 which included new valves.
I went to my local dealer to see what they can do. Tech said they would have to remove the engine and separate the head from the block to get the timing chain rails out. Said there are pins holding them both in. In the service dvd I see one pin holding the top. They said this would be about a 5hr job. Services manager was rude and said he should charge me for the info I'm getting the the tech, who is wrong about having to pull the engine out. So I walked out of the dealer pissed. Looks like I'm really doing this myself.
