I was cleaning the air box and air filter today and found the vent hose from the air box , where the crankcase vents to the air box then out to atomosphere, had worn a hole thru from rubbing on the intake and the seat.

Also I found the clamps loose around the intake.

I replaced the hose and rerouted, ziptied it and the clamps took 5-6 turns to snug up.

Wouldn't hurt to check yours out.

 

Thanks for the info. I found my intake hose clamp loose too.
