Water pump?
My bike overheated today and the bottom hose that goes into the water pump busted. I put a new hose on and it seems to be working okay now. The hose doesnt swell up or anything. I drained the coolant and noticed oil in it. I drained the oil and there was no coolant in there. So just oil is getting to the coolant. i also drained the last bit of the coolant. My new thermostat is busted already(3 days old). I was wondering if i may need a new water pump or if i can test my current one to see if its working. How would i test it?

Oil in your coolant probably means head gasket or the seal for your water pump is bad, i'd look into those first...Either way u gonna have to dismantle part of your motor

Check the o-rings in the heat exchanger on the front of the motor. It's a good idea to just generally clean/seal/go over that assembly if my motor is any indicator of what normally happens to the seals inside it over time. That was my problem. The water pump is actually a dual-seal shaft with a weep hole between the two seals, so coolant/oil exchange through that component is quite unlikely.
If you're like me and you get reeeeaaaal lucky, you can have it go the other way 'round too, where coolant goes into your oil and destroys every oil film bearing in the bottom end of your powerplant, and you have to take the motor down to bare cases and rebuild it. :icon_dunce: |

Your stealership man is right. There are two primary evil-doers in there. There are four directly related to the oil pathway, but only two come into awkward contact with coolant in the actual exchanger, and in my opinion there is a much better way to seal that assembly. You'll see what I mean when you get in there. They're used in compression and are the only barrier between the coolant and oil, and they get undercut by icky hot coolant goobers quite effortlessly. Mine were really perforated, and I have a "young" (20k miles, 1994) F2.

Did you check compression at all? Seeing you did overheat, I would say its a must do.
