I just put a new head gasket on my 02 yz426f and had the cylinder off also to check the piston which was 15 hours old and it was sweet. then i put it all bac togethor and timed and started it. when i ride it, it now has a faint pulsing sound through the tank of the piston doing its strokes. when its hard on the gas it sounds perfectly in tune but when decelerating its making the noise. Any ideas??

i had the head plained bout half a mm when i put new head gasket on.

Runs perfectly

Sounds like the breather hose isn't attached to the cam cover.
