Hopefully a simple question but not too stupid:
1998 mxz 583, the oil pump alignment mark, Should these marks align with the throttle in the closed position, or should should the marks align after a slight opening of the throttle but before the slides open. Would it make a difference in the amount of oil pumped in either option?

Thanks

YUp, align the mark with throttles at idle.

The MXz 670 oil pump is an N9 model (zero oil at idle) the adjustment is as attached:

Does the N9 pump look the same as the other's? Mine looks just like the pic, 96 500 BUt I sure use oil at idle LOL

All Mikuni oil pumps look pretty much the same . Differences are in the lever length, inlet orientation, drive speed (gear size) and discharge orifice.

Ok, thanks
I will take the free play so the marks align with the throttle closed, I recently went on a trip and noticed that I use a little more oil that normal. Your statement about no oil at Idle still is confusing.
