Smoking on start-up
« on: November 30, 2015, 08:38:34 am »
Yesterday I noticed she left quite a bit of smoke while the engine was cold. Is that normal?

I always nurse the engine when cold until it heated up properly and don't ride it like you stole it, but do loosen the carbon now and then.

Did you just wash the bike?

Cleaning products and water boiling out of your exhaust can look rather scary :lol8:

If only, but unfortunately not. Bike was parked for about 3 weeks. Maybe oil seeping past the cylinder while parked? Bike only has 17k on the clock, year old so still "like new".

Mine did the same last week. After standing for a couple of weeks, it smoked when started, looked like a fairly white smoke, which went away after a couple of seconds. My bike is 2 years old with 15 k on the clock?

Parking on the side stand that can happen.
Oil runs down the cylinder and past the rings.

So a very good friend went to visit some friends the first time with his GS.
A beer of two later he gets on the bike which have been standing on its sidestand.
Everyone gathers and oooohs and aaahs about the new bike, until he started it and a cloud or two of white smoke comes out of the exhuast!!!!!
Needles to say he was not happy about his R 160 000 smoking bike!!! :eek7:

My bike is always parked on the side stand (unless parked for long periods, like two weeks, or so).  Never seen any puffs of smoke on start up, other than a bit of condensation at times.  Personally, I reckon this oil past the rings thing is a urban legend.

What could then have caused the smoke? it wasn't really cold and/or humid enough for condensation?

Is white smoke not water and black oil?

Mine is also always on the sidestand I dont have this issuel, but I had the flying brick previously, and I can confirm that is not an urban legend.

It was white with bue-ish colour and it didn't disappear as quickly as condensation normally would.. Maybe I'm smoking something :eek7: :lol8:

I have no idea about the flying brick and therefore cannot say.  For the boxer, I still believe ... urban legend...

I have no idea.

Where would the oil come from that seeped past the rings?

Did you miss the part where I said, that for a boxer this is an urban legend, or do you disagree? :pot: :ricky:
