Since our ride before last, I have been missing my shower cap that TFRYE gave me to put over my radio when I wash the RZRS or get caught in the rain. I took the air filter cover off tonight to wash out the pre-filter and bingo, there it was, in the filter box. I usually put in in the cab to dry after I wash the RZRS and it must have floated around in the cab and got sucked into the air box when I took the RZRS on a high speed road ride after the wash. It was in there the whole 3 days we rode at Trails End earlier this month. I did not notice the RZRS running different. Mark this one up as a DUMB ASS ATTACK.
