We have a big group of people going out to the Glamis sand dunes, and this will be the second time I've taken the YZ out there. I've done the normal maintenance like air filter, oil change, oil filter, chain adjust and regreased and checked wheel/steering/linkage bearings. Is there anything you guys do to prep your bikes for the sand? I was thinking of taping the two side vents on the air box up to prevent a little of the sand from getting in. I think this would affect some of the airflow, but I'm not sure how much air those vents flow. What do you guys think?
