Coolant Flow

I just changed a seal in the water pump on a YZ 400, and was curious on how to check if the coolant is flowing properly through the cooling system? Anyone have suggestions?

yea while the bike is cool take off the radiator cap and start the engine, you should be able to see the coolant flowing thru the radiator. you can rev the engine also and it should move the coolant more rapidly as the u rev it higher . hope this helps
