Bike Smoking

Post by JamieNeve » Fri Oct 04, 2013 1:20 pm

Recently, when I stop I get a hissing sound and then a cloud of smoke rises out form somewhere on the engine. I can't see properly at the mo because of the fairing, but it looks like it's coming from the exhaust type area.

It isn't running hot according to the temp gauge, but I just redid the coolant what did improve things, however it is still doing it.

Any ideas what this could be? Head gasket maybe? not sure!

Any help would be appreciated!

Cheers Guys! :)

does it do it in the dry?

could be water hitting the hot exhaust and evaporating?

mine does it slightly when its raining out, my wingmirrors and screen can become fogged if sat for too long in the rain.

Nope does it in the dry too, and it's like a plume of smoke. May be steam yeah it's hard to tell though. Either way do ya know what could cause this?

it's grey so don't think it would be oil which is blue smoke right? Not like petrol, I guess the only liquid left is coolant?

compression test to see if it is a head gasket leak, is your oil milky? bubbles in coolant?

Think I may know the problem, but does this sound like it could be?

Basically, the top right bolt on the rocker cover has snapped and got jammed inside the top of the engine block. Oil is present around this corner where it is not fully sealed, and is therefore dripping down onto the engine block and burning. I think that this is the cause, can't see anything else that could be doing it.

Has anyone got any tips on how to get this bolt out? Am I going to need to buy an easy out or do they not work?

Cheers!

I'm amazed...................a bolt just snapped ! !
top cover bolts have a sealing washer so that washer is prob gone too.....................lots of oil getting out I would have thought

Those bolts only have a very light torque setting. If it was me I'd try using a small centre punch to tap the remains of the bolt out.


But how did it just snap........................there is more to this IMHO

I must've tightened it too much when I put it on a month ago, I guess eventually causing it to break.

I am often accused of not being helpful...................and perhaps rude. This of course is not true...................but if you'd told us that little bit of information in your original post it would have been very relevant.


I have absolutely no doubt that more than 50% of the problems people on here have with their bikes are a direct result of something they have done with or to their bike in the recent past and without fail they come on here and completely fail to tell the truth.
