ok yesterday i installed a new cool head yesterday with 20cc domes. and i had my radiator cap off and started the bike up. and i didnt see any fluid moving in the radiator. does this mean my impeller took a huge dump on me or do i need to prime the thing first or what, please let me know. i dont want to blow up my motor i know it has liquid in it. but its just not flowing. my neighbor said that the thermostat hasnt opened. but i dont think the banshee has one of thoese. please help me out thanks.
