I guess I didn't know that you had to introduce yourself on these things... but I got scolded by a member for not following the "rules"
So my name is Alex I live in Wisconsin and I own a 09 triumph rocket.
I'm 25 and am somewhat mechanicaly inclined. My two previous bike that I still own and run are a 77 and 79 xs750 (one cafe, one ol'skool chopper)
Alex, welcome from Texas! There are 2 plugs. The upper one is the fill plug and uses an Allen wrench to loosen. The lower one is the drain and is a hex head bolt. Fill the upper plug hole until gear oil run back out of it with bike level.
