Oil Spitting out Exhaust

[duci05]

So i recently noticed that Heidi(my 05 s4r) is spitting oil out the exhuast. Its enough that when you put your hand at the end of the tail pipe you can see the specs on your hand, she went through a 1/4 qt in about 1000 miles. Everything else about Heidi is fine.

She is a 2005 S4R with about 5900 miles on her. Is she ok?? I hope its not what my gut feeling is telling me.

Since you're not seeing smoke sounds like exhaust valve stems leaking.  I'd suggest.

Leak down on both cylinders.
Check the plugs for signs of oil fouling

If both these look ok then figure a valve job, although mileage sounds low for needing a valve job?

Are you sure its oil?  Could be some condenstion mixed with carbon.

I would think that given the temperature of the exhaust, at least some of any oil getting into it would burn causing a smokey exhaust.
I noticed that my S4R would blow a black substance out of the exhaust after I washed it, turned out that water was getting in via one of the slip joints.

if you cant tell teh difference between the two try putting a piece of paper behind and allow it to spit on the paper. if the waer evaporates and leaves behind a black soot its just moisture. if the stuff never evaporates and looks like you just ate a massive grease burger and wiped the corner of your mouth with it, then its oil.

+1 to all comments above. Do you have a stock exhaust? My stock cans had so much condensation develop that the muffley would lean water onto the ground from between the rivets. When I got my arrows the issue dissappeared..

I run full arrows. I have started checking it after long rides now too. And i believe your on to something with the condensation, after a bit of riding it all seems to dissapear. Wow, i never thought of that. Im pretty sure thats probably what it is.

I had a similar issue with the bike burning oil, went through 3/4 of a quart in about 1000k miles on my '05 S4R and it was stalling out if I turned down the choke before it got up to about 140º F. I took it into the shop and it turned out that a vacuum hose had been disconnected somehow. The shop said these bikes can burn oil when something is just a little off. So yeah, they popped the hose back on and its has been fine since (about 4k mi now). So the stuff coming out the tailpipe and the oil loss may be unrelated, although it sounds like you have it figured out already.
