What really is bogging I think my sled might be doing it after I ride in the deep powder and fill up the tunnels and stuff but what does it sound like and what is it?

It does that when I skip water im not sure.

last weekend my buddy was complaining about bogging and we found the airbox was ful of water and ice when someone put the cover back on the ruber gasket had slipped off it mount we cleaned it out on the trail and he said it went away
