there will be no petrol in the oil any fuel mixture will have been fired out of the exhaust port the same way as your exhaust gasses, the smoke you are seeeing I recon is just moisture an unburned fuel residue in that part of your system...

How long have you been running it like a triple, you have just gained yourself 10BHP and a more eficient bike LMAO.

Well if i have infact been running it on 3 the whole time then since september. But i don't think its been that long. Maybe 3 months or something i dno, how embarassing.

Ok i'l try running it but it really is smokey!!!! What about the fact that theres smoke pouring from the downpipe??? is that not a problem?

Hi
If the pipe is smoking it will be burning off any oil and crap it has picked up in the last few months ,just make sure it hasn't got a rag , pipe or a stray plastic bag stuck to it . Take it for a spin up the road and by the time you get back it should be ok.

Petrol can easily have entered the oil if it has been drowned really good. Does the oil smell of petrol?

It's not good to have petrol getting into the oil but if it's only small amounts and the engine has been running then it should have burnt it off. Most will have gone down the exhaust anyway. Personally I'd worry more about the extra wear on that cylinder.

If there is any worry about petrol in the oil then do an oil and filter change. No point pissing about with it.

Yes but the petrol will have been constantly washing the oil coating off the bore giving increased wear in comparison to the other cylinders.
