got a 97 CBR900 with the 919 engine. Just bought the bike back from a buddy after it sat for the last 3 years without running.. Soo i decided to fire it up n what not.. Fired it up, seems to run ok. Now after i turned it off i decided to check the oil and do a change cause of how long it was sitting for.
Went ahead with the oil change, and low and behold.. I have coolant in my oil..
So ive checked pretty much everything and cant find a noticeable leak, or where the coolant would be getting into the oil.
Ive checked the coolant (did a flush to check for oil) not a drop in it, looks pristine.
Checked the spark plugs for moisture, they are dry ( so no blown head gasket)
I put fresh oil in, ran it again, and again, it looks like coolant has made its way back into the oil...
Now i let the bike warm up, and no white smoke out the pipe ( yet another sign it would be a head gasket if it was white)
Ive read that it could be a water pump. So i pulled this off, and nothing from the telltale hole or weeper hole.. I even pressurized the cooling system with it out of the engine and didnt notice any fluid...
Now after reading for hours online, ive seen it could be the Oil cooler oring causing the leak.. Anyone heard of this?
Im at the point now that i am going to change the o-ring, but i really dont want to waste another 4L of coolant and oil to to have this not be the issue.
Does anyone at all have a clue what would be causing the leak or had similar issue?? Please help
