Hey,
When I start my stock 400ex when it is cold I hear 2 noises that I am unsure about. The first noise sounds like I can actually hear the piston sliding up and down, kinda like a hiss. I don't really remember if it goes away once it's warmed up.
The second sounds like a clicking noise in the motor. Maybe the valves?? I thin that one goes away shortly after it is warmed up.
Keep in mind I am new to owning a 4 stroke, all I really know is 2 strokes.
Thanks for any help!!
