Oil Consumption & the GL1200

Postby twocams » Sun Sep 18, 2016 12:10 pm



I went for a 600 mile ride this weekend. To look at a 81 BMW. I know but once you have owned a few, they kinda grow on you. :roll: So I took the Wing for a nice ride to Quincy, Calif. 300 miles one way. I went threw the Mt. Lassen National Park. Hadn't been in that area for about 50 yrs. So took the 30 mile drive that cost me $15 at 35 MPH...won't do that again. Was just a leisurely 300 ml. ride 65 -70 mph. The BMW was a bust, with just 20,000 miles. The $4600 he wanted was just a tad too much. But I was reading about one that had 375,000 miles on it, just before I left home. So still looking for another "Air Head".
So when I got to my hotel I checked the oil to see If I had used any. Nada,none,zilch. Longest ride with this bike at one time. In the morning before I left check again. All packed up ready to ride, took Hwy. 89 for miles. One stretch of road ( all 2 lane) went for about 80 miles 6 cars and one motorcycle passed me going the other way. So maybe you dont want to break down around there.
I was in a hurry to get home now, no more hotels. I did the whole 300 miles 75-80 mph in 7 hrs. of hard riding ( for a old man/old bike). Checked the oil this morning and was on the add mark, not sure how much that is. But have to change oil anyway. Is that normal usage for that kind of riding? Also when checking the oil I get 2 different readings on dipstick. Because of the slant of engine, front and back of dipstick are a little off. Which side do you look at for accuracy?

Not sure what you mean by "which side"?
Always check on center stand.
If cold, start and let run a couple minutes & shut off and let sit a couple mins on center stand.
If just finished a ride and plenty warm just let her sit a couple mins on center stand.
Unscrew dipstick, pull out, wipe off, stick in just to threads contact threads with NO turning it in.
Pull out and look at level.
If between two marks ..... OK.

Pistal, you have a 85 GL1200. Yes center stand, yes let her sit. the dipstick has hash marks on both sides. If you put it into the little hole for a couple min. Pull it out the oil level is different on either side.

If I insert it with the flat surface perpendicular to bike center line, reading on rear face towards rear of bike .... I see the level indicated at what appears to be a slight angle across the face, I read it in center of flat.

The difference in that level line the oil makes from side to side is maybe an ounce. I am sure I have ridden it a few ounces over full even. Not a quart, not even a half quart ... but certainly a few ounces.

On the GL1500 the stick goes in at an angle in both directions. I just read to what would be the center of the stick.

So what you say is, the flat of the blade with hash marks should be placed in the hole front to rear of the bike. Not flat in hole toward the gas tank and floor. Huumm, Ill try that.

Well, actually I don't think it matters much ...... I just look at where I imagine the center of the stick to be, like "the core" .....
..... but what you say will do same thing as its pretty thin where flattened.

And don't screw it in when checking .... just dip it in to thread contact and pull out & read. The marks are a "guide", it's not an exact measurement. For example, the difference where threads start & end between your 1200 and my 1200 might mean a 5cc difference in oil quantity if we both fill to exact same point on our dip sticks .... but neither we nor our bikes will ever know the difference.

In my experience ... no it is not, if engine is solid and tight .. I have ridden all day at 120 to 130 KPH ( 75 to 80 mph ) on warmish summer days, without losing a drop .

Depends on the mileage of the engine, of course . ( Mine has 160 km ) But the 1200 should be not consuming any oil at all if less than 200 k

My 1200 never used any oil no matter how I rode it. I would say you have something going on. Pull the air filter and see if you find oil. I assume it isn't smoking at all.

Oil may be in the coolant also, check the radiator overflow tank. I am new to the Wing but I have found that all engines will use some oil. After all, the oil is in the combustion chamber and it will get burnt up when the engine runs. Running hard in hot weather will increase usage somewhat. I would change the oil and keep an eye on it if no other symptoms exist.
