Black bits spitting out the exhaust

[superman]

Hi all, dont know if this is a problem or not but when i start my bike i have noticed that if i put my hand over the exhaust or hold it back from it abit its kinda spittin fine black specks no black smoke or out exhaust fumes are white but thats normal i think but if i take the bike for a blast the specs stop comin out the exhaust. is this a problem or the start of one, any help appreciated cheers.

Sounds like just droplets of water?

in fact you could well be right, so when the exhaust heats up they evaporate before they get out. as long as its not oil so as a sign the engine is going to break thats great. cheers.

Chances are its not oil, only way for it to get out through to the exhaust is through the combustion chamber, and by then it will have been burnt and will plume blue smoke.
