A smokey bugger

dazthephot · Sep 4, 2014

So when my bike has been sat in the garage for a few weeks it don't half smoke from the exhaust when started up. It normally clears after a few miles but I'm wondering if it's normal.
It's had fresh oil and filter in April. It's a gen 2.

I`d imagine its just condensation if its been sitting for a while and it clears up after a few miles so probably nought to worry about.

I just wondered if there was some sort of oil residue somewhere that's burning off

Incidentally it is smoke and not water vapour

What colour smoke was it ? If its white I`d still suspect condensation as a probable culprit but I`d check your not losing coolant at all, my mate had problem with his 1098 burning oil and his exhausts smoked badly but its was dark, smelt and didn`t go away at all just got worse on acceleration.
Edit just read the above reply re. smoke not vapour so probably not as above then ? beyond my technical knowledge hopefully someone will be along soon that can help :thumbup

Maybe a short video may help someone recognise the problem ? Are you losing oil at all ?

I'll do that mate, I'll also pay attention to the colour because to mind I think it's a touch blue. . It's not loosing oil as I never have to top it up.
I do remember topping up the coolant with water and finding out that you aren't supposed to.
I suppose the fact that it burns off makes me not worry but none of my other bikes have ever done it.

Hmm I may be a bit unduly worried. I went for a decent run yesterday and just started it up and it did look like water vapour. In fact it disappeared really quickly and felt wet to the touch when I held my hand to the back of the exhaust.

The only thing worth noting is tiny flecks of what seems to be oil in the vapour.

Could be the breather leaving oil in the filter housing????

That would make sense actually cos the last time I changed the oil I overfilled and had to clean it out. Perhaps I should check it again.
