    Burning oil when I start up R1200GS

    I've been having an issue where sometimes but not every time I go to start up my '05 R1200 GS I get a big cloud of oil smoke coming out of the back. It doesn't seem to look like oil is burnng constantly (no blue smoke when I'm driving). I noticed it after my 12000 mile service, however as I hadn't ridden it much between an accident where part of the engine was (left side) was replaced including much of the exhaust system.

    Any thoughts?

    R and K bikes will do that. How do I know? I have both and have been embarrassed a few times. Don't overfill the crankcase when you service the bike and use the centerstand when possible. It is a querk of the bike, don't sweat it!

    Make sure you don't fill your oil above the red dot in the sight glass.

    Any engine that has pistons that lay flat does it on occasion. Whether it smokes or not depends on where the engine stops in the cycle and the angle of the engine at rest. I had this happen on K bikes, R bikes, riding mowers with Kawasaki, Onan, Briggs and Kohler engines. Back in my youth, it also happened with VW and Corvair engines. They would blow out a big puff of smoke but they never consumed much if any oil.

    I find it‘«÷s common when I have started the bike and then shut it off before it warms up. Especially on the side stand when the left cylinder head is low. Seals haven‘«÷t heated up, and then oil leaks past in the horizontal cylinder. If the engine is up to temp when it‘«÷s shut off, or if I use the center stand, there is never any smoke.

    As stated earlier, normal for any horizontal cylinder engine. Kohler lawn tractor engines are notorious for leak-by oil smoke on start up.

    Just keep an eye on your oil level and add as needed‘«™
