One way I check on cars, should work on a bike, not 100% tho. Take your radiator cap off, make sure its full and run the bike. Usually a blown head gasket will cause it to spit back out the neck from the compression entering the cooling system. If the water pump is lubed by your oiling system, then perhaps a seal could have blown. Good luck
Yeah it's possible the water pump is leaking oil into the cooling system. You could do a leak-down test to check your head gasket. So you're not getting coolant in your oil then? Also check leak-down on coolant system if you can.
