Hey guys whats up, got the grizzly out on a trail ride the other day,the bike worked flawlessly all day, BUT THEN…… on the way back we encountered a long mud hole the water was about 3/4 of the way up the tires, but i know it had a soft bottom cause i have been through there lots of times when its dry and its always just a mudslick, so being just me and the girlfriend i decided to play it safe and use the 4×4 and put the diff lock on, so i put it in diff lock at the edge of the mud, as soon as i started into the mud not even hardly into it the bike started to sputter like it was gonna die, but then i just kept on the throttle and it rallied around and powered through it never did that again but i was just wondering why it did that

the only think i can think of is that i didnt put it in low when i locked the diff, would that be the problem?
