What's up guys. I just recently noticed oil spots on my floor from my 426. I will ride it around, and after I turn it off and let it sit it will start to leak a little oil. It looks like it is comming from a hose that comes out of the top of the motor, and the hose runs down the side of the bike. Thanks alot.

Its normal for it to drip a couple drops of oil out of the blow-by tube (or crank case vent tube). Sometimes its caused by over-filling the tank with oil and sometimes its caused from running at a high RPM for an extended amount of time.

All the YZF's do it, don't worry. :thumbsup:
