I just attained a Yamaha Warrior. I bought a new filter for it but I don't know where to install it.

 

Never mind...I found it.

 

where's it at?

 

It looks like you are having fun with the new warrior. There is one tip I always give to new owners of a warrior... Go to a hardware store and buy a 6 point 19mm socket for the oil drain bolt. Don't try to use a 12 point or ANY SAE socket.. you will be sorry. Its very easy to strip the drain cap head with 12 point socket.

 

Remove the 3 allen heads on the left side of the case (near the shift lever). Remove the plate and the oil filter is is right there. It takes about 3 Qts.
