Cannondaleriders

So i picked up this speed last weekend, spend all week re-wiring it and changing the fuel system over to new lines/clamps. After some electrical work i videotaped it firing up for the first time in almost 3 years, and it fired up like a champ.

Then immediately puked about a 1/4qt of nasty looking oil from the crankcase tube. Now i thought the scavenge pump was dead as per what ive read around here, but i have oil flow through the frame. And from what ive read about the breather update, this was done (not my be, but previous owner(s) with non-atk hardware) but it looks correct. Im sure i should re-do whats here but id like to try and get this running by friday for my dads birthday.

Any help is appreciated!

Startup, you can hear the oil squirting after i kill the engine. Sounds like a lot of air in the system and im not worried about the color of the oil as its probably 2-3 years old full of water and whatnot.

Oil came from the hose with the nipple (top left)

Drain all of the oil from both sides and inspect condition of the oil. I suspect a blown head gasket or cracked liner is allowing coolant into the oil along with the pressure behind it. If you find water/coolant in the oil prepare for a tear down. The coolant can be from something as simple as a magnesium valve cover ate through. If you find no water or coolant, refill the oil levels to stock and try again. This is a start, but I'll bet you have internal issues.

I figured as much. Its got one of the black powder coated valve covers and there is some gunk seeping from hoses. Anywhere else to get those aside from Brad? I PM'ed him but i know he's been super busy lately.

Call him and leave a message. I know he is in the shop right now.

Will do when i get off work. My buddy cranked it again and it didnt spew, coolant drained clean and the spars are clean and free of coolant as well, when i get home ill drain and refill the oil (im out of filters, HELP!) and see where that gets me.

If your building pressure after running that short of time, yeah, get ready for a tear down.

Okay good news and bad news.

I drained the machine down normally, during this time i completely had redone the crankcase vents and tubes, i had a pretty decent amount of metal in the oil, a bit more than i get with my moto but no chunks of anything to worry about. After buttoning everything back up the oil settled/separated with water and gas mixed in, not pretty but nothing out of the ordinary for something sitting so long.

I drained 2.0 quarts of oil mix from it. A wee bit more than what should be in there. There was lots of condensation, no real coolant from what i could tell, and a bit of gas, old nasty gas. I threw 1.3ish quarts in it, fired it up and it spit a little gunk out then idled fine without anything coming out. I had it running for about 10 mins with only real high RPMs pushing anything out and its all milky crap, nothing solid just spitting and popping a bit.

So as far as getting it running i think ill be ok, ill get some filters and change the oil a few times to work all the crap out of this and see if it runs good while riding.

Update since January, i pulled it out today for a wash which to my suprise cleaned up well! I yanked the clutch cover off and found the scavenge gears are half stripped, which explains why it would randomly puke out oil. Also upon cleaning i pulled in the clutch lever and felt a really hard pop from the slave cylinder, safe to say something broke inside that and now i have a dead floppy lever. Any ideas what a replacement slave would cost? Also, anyone have a source for the steel pump gears?
