First time changing the oil on the Z400. First question where is the oil filter located? Second question whats the recommended amount of oil that goes in. I picked up 3 quarts and a new Suzuki filter. Hopefully someone can answer these and save me some time this evening. I need to pick up a manual soon I guess.

Thanks,
Jeff

 

2 Liters of oil is right, a little more than 2 Quarts, drain both the crankcase and the oil tank, 2 drainplugs!
The oil filter is on the side of the motor, If I remember right, About 5 small bolts, and the cover comes off.
After you fill it up you need to run it for a few minutes so the oil gets sucked out of the tank into the motor.
It's a dry sump motor, so if it sits for awhile the tank can read low, but oil has drained back into the motor.
Always run the motor for a few minutes before you check level. Also DO NOT run the motor with the oil tank plug out, Heck of a mess. Yes I did that once on a XR650, the tank is in frame and you fill it up next to the triple clamp, blew oil all over the bike and me.
