Oil change bleed screw??

5 posts in this topic

On the '06 YZ450F is it imperative that you run the engine and blled the oil system after an oil change? I havent figured out a way to do it without making a heck of a mess.

No. You are not bleeding the oil system, anyway, you are testing for oil pressure. All forced oiling systems that come to mind bleed themselves.

When checking for pressure, it only takes a tiny bit of oil seeping from the copper o-ring. Start the motor, open very slowly, if it is seeping, you have pressure, close it and you are done.

On the other hand, if you turn that bolt a full rotation and there is no oil seepage, shut her down, and find out why there is no oil pressure.

Hope that helped,

Shane
