5 posts in this topic

Hi all,

I dont know much about the engines and motrobikes and I just started riding offroad, so maybe this is gonna be stupid question for most of you...

Where supposed to go other end of Cylinder head breather hose, one is connected on top of the engine and where should be the other one...

Thanks a lot!

PS: And sorry for my english but hopefully you can understand me.

Runs down the left side of the engine and vents just in front (about 4" away) from the gear shifter.

should be a couple of brackets mounted on the way down to secure.

It shouldn't go to the air box. It should do as Rich said. It's open ended. If you don't have brackets, it's not a big deal. It won't go anywhere without them.

It should only go to the air box if you ride through deep water/ river crossings on a regular basis and need to the protect the breather form being submerged when the engine stops running.

Historically people here have had problems when their bike stops running in a stream crossing and they attempt to restart the engine with the breather hose submerged. some water may enter the engine through the valve cover.
