Motorcycle Repair: water in oil ?, losing coolant, water intrusion


Question
There is a yellow goo in the oil of my bike and I don't know what it is. 1999 ZRX 1100

Answer
Hi Dalton.
 You have water intrusion into the engine.  Either water has gotten in from some outside source, or if the fungus (that's what it is) is a large amount, then you could have a cracked block.  If you have had an overheat problem, then that is what it could be.  If it hasn't been overheating and losing coolant (without spitting it out onto the ground) then the problem is moisture getting in from another source.

Flush the system and change the oil.

Good luck.
