    I picked up my new 990 in April 2013. I've put about 4500km on it and it developed an oil leak on the left side of the engine. I removed the tank to take a look but can find any obvious leaks. Seems to be somewhere behind the oil tank. Any ideas? The dealership is 8 hours away so just trying to trouble shoot a little on my own.

    I had the same problem with my new 2012. Turned out to be the hydraulic cam chain tensioner. I found it by dusting the motor with foot powder and letting it run until the fan came on. I put a little bit of anti seize on the threads and tightened it back up, and no more leaks, although I'm sure the "right" way to fix it would be to get a new crush washer.
    If that's not it this thread is full of all kinds of options-http://www.advrider.com/forums/showthread.php?t=483183

    Well damn.. That was the problem. Haven't fixed it yet but I cleaned up the bike then went for a quick spin. Sure enough the source was that plug right behind the oil tank. Thanks!!

    Just be careful when you take it all the way out, the tensioner is spring loaded and will fall out. Might try tightening it a little, I was able to get to mine with a 8mm ball "L" allen.

    Thanks for the tip. Not much room to work there. I think for now I'm just going to tighten it a little and see what happens.
