I have noticed that sometimes when I put my 1150 gs 2002 on the sidestand after starting it it smokes leaving a small cloud as I live.That happens only sometimes .Is that normal?
 
Yes, they all do that, sir. Park it on the sidestand after a run and it will sometimes smoke on start-up also.
 
Thank you for your replies guys, as for the pope I didn't knopw it either when are they going to vote for the new one?
 
Near miss !

Staight over the pate, my 1975 GL1000 does this as well, is that relevant ?
 
yes ,because it is the same engine configuration just four or six pots depending which one it is .

the side stand is the culprit . it means you are putting 1 in the case of the bmw and two or three cylinders upside-down.:D
 
white smoke

AT the risk of sounding like a boring flat cap wearing techno head, :rolleyes: , the reason they smoke is because when the bike is on the side stand, the left hand cylinder is pointing downwards, which means that a small amount of oil can run past the piston rings in to the combustion chamber. Which measn that when the enging is started up again, the oil has to burn off. Voila! thats yer smoke. My K series wot I have just changed for the GS was a nightmare sometimes, clouds of the stuff, very embarrassing if nothing else. It still it despite fitting new rings, even tho the old oones were in perfect condition.
Call it character if you like!!! they do indeed 'all do that sir'!.

Design fault

The original 1975 GL1000's were built with a design fault in that the gaps in the rings were all lined up at the bottom of the cylinder. This does indeed lead to oil seepage if left on the side stand, consequently it makes smoke like a WW1 destroyer when started.
 
Thanks a lot you guys I thought I was the only one.
Cheers !!
 
Smoke from exhaust..

White smoke is condensation, this is due to the combustion process creating water droplets and you notice it more on chill mornings,evenings.

Oil draining or rather seeping in through the inlet valve guide oil seal or running up the cylinder wall when on the side stand would produce 'blue' smoke.

When the engine is shut down there is a tiny amount of vacuum left over after the last induction stroke and this aids any residual oil to seep past the inlet valve stem oil seal, hence the smoke.

Most bikes and cars do this to a more or lesser degree, and on the boxer engine it is one reason for increased oil consumption.
