Oil Change on my Goldwing GL1000

Postby goldie78 » Tue May 03, 2016 9:19 pm



I thought i read this in some motorcycle mag. or book , or saw it on here somewhere... When changing oil in my GL1000, pull plug wires so motor doesn't start and turn the motor over to pump out oil trapped in places that wont drain out normally...Please confirm my thoughts or tell me i'm off my rocker..... :? :? :?

Me thinks you may be..... I can't think of any reason to do that. What small amount of oil left isn't going to be worth the risk of cranking with no oil.

Right, and you really don't want to be cranking the engine when there is NO oil being pumped around to lubricate the innards.

I go out and ride the bike until it is warm, then drain the oil while it's still hot - this means the oil is thinner, and it drains easier (and faster).

If you're really worried about it, add half a can of Seafoam to the crankcase, ride the bike gently for half an hour, then drain the oil. The Seafoam will both thin the oil as well as dislodge sludge from areas of the engine that don't get as good oil flow (starter sprag clutch, for one), and it will all come flowing out the drain bolt. I do this as part of my final oil change every year before putting my bike away for the winter.

I use the mc jack to tip the bike as forward as possible.

You still can never get it all out I don't think.

I run seafoam gas treatment in the first and last tank of the riding season,
I'm assuming you mean seafoam engine treatment.

After draining the oil on my old 1000, I always bumped the motor over a couple of times to get the remaining out. I don't know if this is the "correct" way to do it or not but by my thinking, there's enough residual oil left on the internal surfaces that it wouldn't hurt.

Each piston of a GL1000 has a diameter of 2.83 inches, for an area of 6.29 square inches.

Running at a median compression of 170 psi, that's 1,069 lbs of pressure being exerted on the connecting road, and on the crankshaft bearing.

Yes, over HALF A TON of pressure, every time the compression cycle happens. And that's just spinning the engine when it's not even running!

The only thing between the crankshaft journal and the bearing, protecting one from grinding against the other with 1,069 pounds of force is a microscopic layer of oil.

Do you REALLY want to be cranking your engine over when there is no oil being pumped up into those bearings?

Particularly on your GL1000, where engine bearings haven't been made in many years, and are rarer than hen's teeth?

If you're going to do this, at least first remove the spark plugs, so that you have no compression, thereby no force being exerted on the bearings.

Spark plugs were out, boss. I wasn't that drunk.

I know lots of guys who leave the kill switch on and buzz the starter a few times after the majority of oil has drained. The oil you are getting to come out is from the clutch and it is a surprising amount. I never measured it.

The crank bearings are not dry. If worried about it, pull the plugs and use a wrench.

In the big picture, it probably doesn't make a lot of difference.

Excellent advise, I couldn't agree more.

Actually you never get rid of "all" the oil at any given oil change. Regardless of the vehicle or engine theres a small amount that remains trapped and an oil film is left on the vitals.
