Seems like you may have overfilled your radiator. Check the fluid level...if it's still visible, ride around again and see if it continues to spit out of the overflow.

Did you flush and refill because it was low ? If so you have a a blown head gasket. It could be pulling in air and pressurizing the cooling system. I've had it happen before.

+1 ^ Was there black floating sediment in the radiators before you flushed them? I'd say blown h gasket or ur Head isn't torqued to spec. May as we'll change cap too.
