I use Motul 10w40. Check with your local dealer.
9.8 ounces
3.5 quarts, or 3.2 liters
9.8 ounces
Right side, just up from the foot brake. It's just below the oil level window. Check the oil with the bike on the center stand. Wipe the glass, have the engine running, look in the window with a flashlite, have someone turn the engine off, and you will see the oil level settle.
The oil drain plug is on the front of the motor below the oil filter.
7.4 OZ atf
10 40w engine oil!
Should be just a little over 4 L. With the filter. With bike on the center stand, oil in, run the engine a few minutes, and with a flash lite look in the little window, at the same time shut the engine down and you will see the level very clearly as the oil settles.
