Bought my dream bike (late 2004 R1200GS with low mileage – ±7500 miles) and loving it. However I’ve been looking around the forum for potential problems to watch out for and upon inspection I realized I’ve got a rear main seal OR gearbox input shaft seal leaking. My clutch still feels solid en I smell no oil. The oil coming out the seam also smells like engine oil – not gearbox oil. Unfortunately my bike is out of warranty. I would like to see if I can negotiate with my local BMW dealer for fixing under warranty due to my low mileage but I think it will be wishful thinking. I also don’t want to take the chance and let them split the bike only to tell me that they can’t help me with a warranty type deal and then I have to pay the high labour cost. So I think I’ll be splitting the bike myself, but now comes the questions. I have the new Hayes manual and I’ve been studying it carefully, and it doesn’t look difficult at all. At this stage I need help with the following: In order to get to the gearbox the whole half of the frame needs to come off. Now the stiff break line going from the ABS unit to the position as shown on the photo needs to be disconnected – or does it? Otherwise the sub frame can’t be disconnected from the gearbox and engine?! Is there any way to do this without having to disconnect any break lines?
