1985 GL1200 "smoking" on Start Up

Postby Rednaxs60 » Sat Dec 12, 2015 10:42 pm



Since the weather has not cooperated here in the Pacific Northwest, have not been riding the 1985 GW. Left it on the sidestand and notice that t smokes a lot on start up. Knew that the "boxer" engine of the BMW was prone to this, but did not expect the GW to suffer the same fate. When I was riding it daily, this was not an issue. Decided to try an experiment. Operated the '85 until it was warm and no more "smoke" coming out the exhaust, then put it on the centre stand. Left it for two days, started it and noticed almost no smoke coming out of the exhaust. Question to the forum; has anyone else had this experience. The '85 has 116K Kms. Cheers

The answer is yes I have an 85 and had a 84 if you leave them on the side stand for a couple of days this will happen. As the oil will slip past the seals and in to the heads. I always put them on the center stand to help stop them from smoking on startup. But this is normal and nothing to worry about.------------------------------Hal

Was fairly certain this was the case. Thanks.

On another site someone posted a Honda service bulletin about this situation.
The bulletin was for a 1975 GL 1000 but should apply to all the early flat fours.
It stated that when left parked on the sidestand the horizonally opposed engine would permit motor oil to migrate past the piston rings and into the combustion chamber.
Because of this it smokes until this seepage is burned away.
Made sense to me, both mine do it some.

Here is the link to the service bulletin:

Most of us without ctr stands, shut the bike down straight up, tip the bike to the right for about ten seconds, then place on side stand. This allows oil in the left cylinders' oil to drain as it's still hot. It almost eliminates the blue fog. You can still get a puff if the rings line up or if a group of Harleys are around.
