Oh and BTW, this is also true (2 oil plugs) for every Kawasaki engine based on the original 1984 Ninja 900. Among others, this include 1984-1986 Ninja 900, Eliminator 900/1000, 1986-87 Ninja 1000R, 1986-2005 Concours, 1988-1990 ZX-10, 1990-2001 ZX-11 and 2002-2005 ZZ-R1200.
Try this, drain the oil from only one plug, then crack the other.
You'll see a ton of oil come out.
I like to start with as much of the old oil gone, I let it drip for at least a half hour.
there is about a half a quart of oil over the front drain plug. It needs to be removed with every O/C. You may have to remove the 2 lower screws on the right side fairing lower to get to the front, but it well worth the hassle
YESSIR! I spent a couple years scratching my head before I figured that out on my 1000R's.
Never could understand why they took like 1/2 quart less than they should have every time I changed the oil.
On my first bike, I thought maybe somebody had swapped motors, and put a ZX 900 motor in (nope).
Also, always worthy of repeating is that all you guys want to make double sure on the ZX11's, (as well as the early ZX10's and 1000R's) to fill and run the oil level right to the top of the sight glass. Use the search function if you need more info on rod bearing problems associated with oil starvation.
Doh! Just changed my oil yesterday and totally forgot about drain 2. I tend to slightly overfill to keep my number 3 bearing from going. I'll add the full gallon jug of mobil 1 but this time it's way overfilled. Now what... Keep it at 4.5 qts or suck .5 back out?
I would NOT leave it over full. If you're anal about changing oil (every 1500-2500 miles) then a half quart of old probably won't hurt too much. If you tend to put off changes, then I don't know. If it were me, I'd get the level right and then run it 2K. Depends on age and condition of what you pulled out.
Can you offer any guidance for the oil lines that connect to the pan? I recently replaced my pan and did not make a drawing of the lines and where they go. The oil line coming in from the head actually uses a 14X20X10 gasket that leaks when in place, so I am afraid that I have missed something.
