Don't worry about the crankcase vent hose being disconnected. It vents the ring blow-by to atmosphere and the flow is OUT of the crankcase so there is no issue. Before there were emission concerns, crankcases were vented directly to atmosphere but now are routed into the airbox/air intake so the crankcase gasses are burned in the engine reducing pollution.
ErikMotoMan: "People struggle with many things in their lives. But the answer to struggle isnít MORE struggle. Itís peace. If you want more joy, peace, love, happinessÖ you have to GIVE those things first. You have to THINK those things. You have to have faith that theyíll come to you, despite what you may see. The truth isnít in what you see with your eyes. Itís what you feel in your heart."
