Hi again i was talking to a friend today telling him about this site,and he asked me to ask you guy's why his 99 scrambler 500 4x4 would lock the front wheel's while doing a wheelie at around 40 to 50 mph,and it's not even in 4wd?Has this happened to anybody else and what could be changed or modifed to stop this.Thank's again.

 

My Xplorer will spin the front wheels, but will not 'lock in'. I can stop the front wheels if I hit the brake (not so hard as to slam the front down) while riding the rear. I think it is just the axles trying to spin the wheels thru the bearing friction.
