i bought this bike new in 07 its an ac 400 4x4 trv. i got sick right after buying it so there are hardly any miles on it.it shows in the manual to have a diff lock but i cnt find where to turn it on at.is it electronic like a limited slip or is there a switch somewhere?any help is greatly appreciated.thanks

 

my 07 500 auto has a lever on the right handle bar. it just has LOCK on it with white index marks on it. not shure about the 400 but dont think its ele.

 

If I remember correctly there should be a lever on the right side of your handlebar which when you are in 4wheel drive stopped you can lift over which will engage yor diff lock.

 

thanks, my 650 v2 had that switch but this one dont.thought it might be electronic.thanks for the help.
