Default 1994 440 XCR oil out the exhaust?

I just picked up a 94 XCR 440. I drained all the gas and put in some fresh fuel. Changed the plugs and it started right up. After running it for a couple of minutes there was a puddle under the exhaust about 24" around on the ground. I wiped it off the driveway and it was pretty black. Any ideas what may have caused this?


Thanks,
Zach

It could be a combination of a pile of fogging oil, a bit of condensation. Did it clear up after the initial mess?

I didn't notice it until l shut it down. I am not sure when/if it cleared up. The guy I bought it from ran it for a minute and it did it in his garage. When he ran it, one plug was fouled and it was bogging bad. When running it on the stand and reving it there was a bog around 7,500 rpm. I did check the compression and its good. I am planning on cleaning the carbs. Does anyone know what jets it should have?

your needle and seat's are leaking. pipe was fuel of fuel. fuel is a solvent so it cleaned oil from inside the pipe. these were steel needles in a brass seat. very common issue on older sleds now. every older sled in my shop with original needle/ seats have been bad. and done stuff like that.

Thank Rick,
I was thinking along the lines of the needle and seat. I have a carb kit and will rebuild the carbs. I may bring it up to you once and I done to sync the carbs and go through the clutches.
