smoke on startup!

[mark2jag]

Hiya Folks, just a quick question for you... 2010 GS1200, with a grand total of 700 miles on it. Took it to Loomies today for a quick blast (and BOY was it quick!!) and after I'd had my usual cheesnham toastie(any releation to a cheltenham toastie) and my cuppa and a quick fag or 2 i decided enough was enough and can i go the feck home please... Started the bike and at this point should tell you it was on the sidestand, and produced a plume of light blue smoke the red arrows would have been proud of. Thought I'd best not ride off on it till it stopped doing it, which took about a minute. waited till the engine was warm and stopped somewhere safe and gave it a bit of revs to see if it was still doing an impression of a steam train, and it wasnt so rode home. I do remember someone going on about old K series engines filling one of the cylinders up with oil if left on the sidestand but not on a GS12 surely(Dont fcuking call me Shirley!!!!)

Thanks y'awl!!!!!

ive brought a 2010 gs and on the pdi sheet i noted it stated check for smoke on start up, i was alittle worried so gave the stealer a call and was told by the tech that they found it to have too much oil in the bike!!

Mine 06 GSA has always done it occasionally and for no apparent reason.

I'm guessing a little oil holds itself somewhere and just blows out. Mine's done 64,000 now and it's sweet as a nut so I wouldn't worry

It's not uncommon for any of the GS engines from the 1100 onwards to smoke on startup after being left on the sidestand and is due to oil seeping into the combustion chamber on the 'low' side while standing and then burning off when fired up. I used to think it was worn valve guide oil seals as it is worse on high milage bikes but I'm now more inclined to believe he theory that it's oil seeping past the rings of the 'low' cylinder from the crankcase. The seemingly random occourance could be explained by the fact that the rings normally rotate in the grooves and at random the engine will be stopped at a point when all the grooves are at the bottom of the cylinder (nearest the floor) allowing a small amount of oil left pooled by the rear of the piston to leak past and into the head.

If the bike is left on the main stand then it won't smoke, ever. If the bike is full of oil or worse, overfilled, it's possible that more is splashed up onto the bores and hence make a slightly larger pool in the downhill cylinder from which more can seep past the rings.

That's my theory anyway.

It doesn't seem to indicate a problem or affect the performance of the bike.

However, I'm very surprised it gets past the oil control rings in the first place and that it's happening on low milage 2010 bikes, unless they are overfilled.

That happend to mine once just before the 600 mile service when it was parked on it's sidestand for 30 minutes and it's never done it since

Well blow me..... if it aint just happened to me, not ridden the bike for about 6 days, its 2 months old with 2k on the clock, its been on the centre stand, pulled it out this morning and it just, and i mean only just turned over, it caught and started but the smoke was everywhere, pulled away and it was fine after that.

Just waiting to go home soon and hoping it will start

Making smoke.....

Mine ( a 06 GSA) did that.... but I had just pumped 30 litres of diesel out of it

 

[LBL]

Started up fine on the way home with no smoke

oh well onwards and upwards

How were you able to get a diesel nozzle into an unleaded tank?

My previous 57 plate GS did it twice in 6000 miles, but the new 2010 GS in 1800 miles has smoked out the neighbourhood on 4 different occasions, and it makes no difference if it was on the centre or side stand, dealer appeared to not know the issue ever existed when I called. I will be going in for a check up and a steering straighten. Hindsight....should have kept old 57 plate.

06 GSA, more than capable of accepting a French BP garage's diesel nozzle. My own personal Deep Water Horizon

Now that wouldn't have happend in a good old British BP Station

Just a thought,but........ With this smoke being a very light blue in colour, whats the chances that what I'm actually seeing is excess fuel not oil. If the choke was on then would it do this (think im right in suggesting 2010 model to be fuel injected, or am i barking up the wrong tree). I'm asking as I've just come back from a 100 mile thrash (err i mean 100 mile bimble!!) and waited the required length of time and oil level appears to be ok (tiny tiny bubble of air at the top of the oil observation window!!!!. Really not slagging the bike off as i still think its the dogs danglies, but I did sort of wonder, like you do!!!.



Ta very much people!!!

Hmmm...mine is going in next week to dealer for a check up, will post what they say apart from the usual, "keep an eye on it". The bike runs like a dream though, and having had it before on the previous model, I am not to concerned. Just more embarrased by causing a smoke screen where I park, and of course the laughs form other bike owners.

just on the fuel note, the smoke from mine has distinct smell of oil, so going along with previous comments I guess it is some oil seeping through.

watch this space if you can see it through the smoke.

 

[Brown_Dog]

Had mine about 6-7 weeks now and had this happen twice.

Did concern me at the begining but the more I read about these bikes on forums etc the less I worry

Mine looks like its had a touch too much oil in from new and after the first service. Just going to ride

Still love it.

Never had that with mine but when I started it today after it was covered in ACF50 at Bahnstormers there was so much smoke I thought it was summer again and someone ahd lit a bar-b-q

 

[Tuono1961]

Same here after an ACF50 treatment this weekend. People were staring at me in this great cloud of smoke whilst at the traffic lights this morning
