Gl1000 oil, why does it take forever to drain?

Post by YourJere » Tue Dec 03, 2019 8:38 pm



I thought I had a leak, through the plate on the rear of the engine now I am pretty sure that my oil is way overfilled, because it took so long to drain that I must not of drained it all, why does it take so long? I did it on the center stand as well.

Is your engine warm before you drain the oil? It is thick and will take a long time (and won't fully drain) if it's cold.

Also this is a little off topic but I ordered a new petcock from saber cycle a few months ago, and its holding up pretty good, I've just been super gentle with it cus I'm scared it'll fall to pieces knowing their reputation.
Still not a supporter of that company but I saved $20 since the next cheapest petcock I could find was $40 on ebay (brand new)

Two thoughts. Okay, flickers, maybe not thoughts.
1. Was the oil level in the window visible? If not you could be dripping gas slowly into the crankcase. This thins your oil and can lead to bent rods. You’re in Texas, it shouldn’t have taken long to drain the majority of oil. What a fair amount of us do is let the majority of the oil drain, then with the stop switch on so the motor cannot start, roll the starter a few revolutions, let it drain, repeat a few times. This will help remove oil in the clutch and scavenge pump. You get a cleaner change that way, but if you change regularly it probably isn’t necessary.

2. If it is slow, perhaps looking into the drain hole into the crankcase and see if anything has dropped in there to be plugging the opening. I know people have dropped things through the oil return galleys in the heads before. The head bolt washer of the lower center bolt is easy to fall in there.

If so you could likely get it out with a magnetic tool.

With the valve cover off there is a pretty good window the access the crankcase area.

I wasn't sure but just to make sure I checked for gas in my oil, that was the thinnest oil I've ever seen, mixed all with my gas.
Whats next, guess ill search the site a little, my gut tells me its gonna be some fairly tough work thats okay with me as long as its straightforward.
Luckily I do not run the motor often so i dont think any rods are bent and ill make sure not to start it any time soon.
Thanks for the tips and advice,
I thought I was almost finished with the motorcycle lol

**** my bad, this is a carb issue.
My oil may be useless now but I KNow for certain, my rightside carbs were flooding badly, so bad liquid gas was coming out the exhaust.
I was expecting to have to change piston rings or something ive been dreading

Gas in oil is generally stuck floats. Sometimes a dose of Seafoam (one can in one tank of gas, run it for 15 minutes, let it sit overnight, then run through the entire tank) is enough to fix the problem. Otherwise you're looking at a little more in-depth carb work.

Back to the 'speed' of draining... did you remember to remove the filler cap first?
I'm not so sure about an inner child, but I have an inner idiot that surfaces every now and then.. :mrgreen:

well the oil draining isnt an issue now but one of the carbs on the right floods so bad that fuel pours out the exhaust still,
I just took them out and the floats are all adjusted about the same and shouldn't be sticking or anything, I think the float valve isn't any good, but also Im not that great with adjusting the floats, but it basically seems like I run the engine, fuel pumps and the carb doesnt stop it, goes to the cylinder then out the exhaust. Im gonna check my spark plugs right now and see which is wet and I guess tomorrow if IM up for it Ill replace the float valve with the 40 year old one and hope it checks out.

I wish these were the types of carbs where you could just blow on the inlet and know if the float valve works.
Any good carb tips for tomorrow when I mess with em?
I don't even know how that much fuel comes out the exhaust with how small the carbs holes are

Also I just bought a 4 carb sync set for when they are ready

So i checked the plugs and the rear wet was soaked, and when I ran the starter with the kill switch on off, that cylinder was misting gas out the spark plug hole, so I know thats the culprit. Just not sure if its the float valve til swap em, and if thats not it then I cant wait to pull it all apart again
I hate goldwing carbs but I would for sure buy another goldwing once this one is finished.

Typically, when you drain the oil on a GL1000, about 1 quart of oil will not get drained out of the rear of the engine. You can get most of it out if you jack up the rear of the bike so the engine is tilted forward. Honda should have added a drain plug near the clutch.
