Mine has that soot also.A little break in blowby to be expected I guess.

 

I hope so cuz mines got it too.

 

Mine does that too, it's just the water/condensation from the cold exhaust system mixed with the carbon that is in there from combustion. Normal. It's not oil.

 

Maybe it is running rich from the factory?

 

Coreytrevor detected no oil usage after 5k miles.that's nice to know.
Might be interesting to get a look at the plugs.
Good point about the condensation from a potbelly bathtub of an exhaust!

 

the black could just be that the engine is running richer early in it's life until a certain point. Could be unburned fuel. Just a complete W.A.G. though.

 

Most of that soot/carbon is probably produced when the engine is cold, running on a richer mixture and not burning the fuel efficiently. Just need to take really, really long rides!

 

This could be tied in to the defective thermostat post....

 

Someone needs to find out.

 

Hey, good point!

 

Perhaps the bike is running cold, not burning off water vap and the efi is running the bike rich.......hmmmmmmmmmmm

 

This could be a big problem....

 

Need to read the plugs.

 

Cars generally run very rich at cold start in order to heat the catalytic converter to the point where it begins working. Since emissions crap has started creeping into motorcycles I'd begin assume that's what is going on.

 

Like others have said, its carbon and moisture. H2O is actually a bi-product when gasoline is burned. This and the condensation on the inside of a cold exhaust (smoking exhaust on start up, thats mostly wator vapor) are what make for the moisture. Carbureted bikes usually have a choke that when engaged, chock off air from the engine making it run rich. This allows the engine to warm up faster. Same principle with fuel injected engines but its done automatically. When the engine runs rich, you'll get a lot of carbon deposits. Combine the water and carbon and you get what you described.

 

I too would say its normal. You can try running a tank of race gas on a track day at WFO race pace and i bet the pipe will turn a nice gray-white color.

 

Did you do the suggested easy break-in, or the alternative hard break-in? Easy break-in will cause the rings to seat slowly if not at all which will cause more oil blowby.

 

i've riden it normally since i got it.
I agree that water is a by product - that doesn't concern me. The black heavy soot is a product of incomplete combustion or oil blowing by the valve seats.

 

My fan doesn't turn on till like 221 not like my r6 comes on at 210. Seem a little hot to me. But this has to be the most fun I have had on a bike in 30 years of riding

 

today mine came on at 215F. The bike has only got this warm at idle and stationary.
The bike seems to run about 150F on average.

 

There are three CBR 600RR's at our house, two of which do track duty........the fan turns on at approx. 221 -223 degrees on all three of them. That kind of number is pretty normal.

 

My YZF is the same. 212 or 100C.

 

My bikes live outside under covers when not being ridden. In the morning, they've all always spit a little water out the exhaust at 1st when warming up. The FZ-09's no different. The condensation is just taking some exhaust soot with it and making itself more noticeable in the form of spots around the exhaust outlet. I wouldn't give it a second thought.

+1... 'sactly. Truly not an issue. My bikes all live inside when not being ridden, and even they all do it to one degree or another right after a cold start. I think the exhaust outlet design on the 09 just makes it a little more noticeable because of the way the outlet collar catches the moisture/soot combo on the way out.

If we were seeing that kind of thing after the engine & exhaust are fully warmed up, then we'd be looking at a real problem.
