Put the bike back together and tested it out. Works perfect now! I figured the chances of it being the water pump blowing the oil seal were low, but it looks like its definitely the problem!

With the new radiator it actually runs better than ever! But of course when you fix one thing something else has to go wrong. While fixing, I accidentally cracked my windshield, so now I need a new one of those. I also have a couple mysterious lone bolts that don't seem to have a home anymore. And my starter is doing funny things- sometimes when I try to start it just makes a loud clicking sound and doesnt turn over, I think something's loose.


So I think something to learn from this, it is possible to blow the oil seal in the water pump, don't always assume it's the head gaskets and block, and check the pump for oil pouring out before doing anything else
