This motorcycle tutorial shows you how to do a PCV mod on a Kawasaki KLR650. The PCV mod is putting a one way valve in the breather hose from the engine into the airbox.
Purpose: only lets the engine case exhale, not suck air back in.
Side effect: potentially reduces or eliminates your engine's oil drinking problem
If you do this mod and don't like it, it is easily reversible.
