i have a 04 vee an as long as i have owned it i uses oil. it dosnt smoke or anything and there is no oil leaks. just curious if anyone else has this issue. i do run full synthetic an a guy i worked with said since synthetic is so slick that it might be getting past some seal or something.
Step 1: stop using synthetic
Step 2: (this should be done before step one) You should have followed your manual's break-in procedure.
That's why I build my own engines or buy my bikes new.
People don't know how to break in an engine and the oil rings don't seat properly. The manual is pretty clear on how to do the break-in properly, and the proper procedure is obvious to anyone that knows how an engine works (in the kind of detail that would interest an engineer, not in the layman's basic understanding of the four strokes), but people either "baby" it or abuse it, and that's very bad for seating the oil rings.
Motoman's method is stupid; power? what? Compression rings will seat just fine if you just idle the engine for 30 seconds; it's the oil rings that require a proper break-in (that, and many other parts like the camshaft). My bikes are rarely washed and may not look good, but all the mechanical bits work better than new.
Sorry, you, or the previous owner, ****ed up your bike. It's not big deal though; it just means you' re burning oil until you rehone the cylinders and install new rings (and follow it up with a proper break-in).
I'm 30 some thousand kilometres into my wee ownership (easily my 20th bike, many of which I have built myself), and my bike doesn't burn any oil. I get no blow-by either, and my oil stays clean for the first 3,000 kms after I change it.
My 1985 BMW with over 250,000 kms on the odometer (no engine work yet) behaves the same way.
But then again, I'm just a duck, and it's been established long ago that I don't know what I'm talking about. It's just a funny happenstance that the suzuki engineers agree with me.
Maybe we should have a sticky on how to break an engine in properly. I could write it if I knew how to write better.
