When I took the front fender cover off my recently acquired 2002 Grizzly 660, (to make sure there were no mouse nests in the Ultramatic air intake), I found that the previous owner had cut about a two inch hole in each corner of the fenders (inside the air chamber, one right next to the radiator cap, and the other in the opposite corner. The one next to the rad. cap is not nearly big enough to get the cap off through it. Any ideas why a meticulous guy (he was a Pharmacist) would have cut those holes?
