I asked another Maxim owner this very same question this morning about my Maxim 650. He showed me that it is is in between the two middle down pipes on the very front of the bike. It's a round thing with vertical fins and a single bolt in the center of it. Having not changed mine out yet, I'm just going by what he said! ;) Ok, I checked out www.bikebandit.com and found this diagram : http://houseofmotorcycles.bikebandit.com/partsbandit/assets/schematics/Yamaha/YA4167_09.gif Apparently the filter itself is under the metal cap I was detailing earlier. I'm going to order one for mine now that I know what it takes! (not a plug, btw)
A Yamaha Maxim 650 motorcycle has a 4-cylinder engine. The Yamaha Maxim 650 will hold 3.1 quarts or 2.65 milliliters of oil with the oil filter attached.
Hypoid 80/90W. Check www.xjbikes.com
a small round window rigt next to the back brake lever
Look under the bike for the drain plug under the motor area.
I use 20w- 50 non detergent oil for motorcycles in hot weather and 10w-40 The Maxim holds 3.7 quarts when you change the filter which I recommend highly.
I have a 650 yam maxim shaft drive. I forget the ml amount but it measured out to be 21/2 quarts of oil exactly for the crank case oil. I'm having trouble compressing the front break cylinder for new pads.
no oil filter
20/50
yamaha xt 125 doesn't have oil filter.

on my 1982 maxim 550, the oil fill cap is the little cap right above your rear brake. The oil filter looks liek its in the front bottom area, just un bolt that to drain, and unscrew the cap by the brake to fill.
the oil filter is under a plate thats held in with some allen screws on the right hand side of the bike next to the back brake lever foot pedal.
