Title: Yellow crust
Post by: idris on October 05, 2019, 07:55:03 AM

Having taken the air box off my ZX6R R9F I've found a yellowish crust (like some fluid has leaked and evaporated) around the air pressure switch hoses.
Any idea what it might be?

Will just be some oil mist. Nothing to worry about.

Airbox is connected to emission valves on top of cyclinder head cover. There will be minimumum oil mist gets into the airbox. Nothing to worry about.

Then I guess it's probably coming from where the hose from the cylinder head attaches to the air switching valve. What does that valve actually do? (I forgot to reconnect it once and the bike ran like ****.)
