    Boyesen Supercooler Water Pump Cover and Impeller Kit

    Robert in WA

    Wow, great results!

    I paired this with a high pressure radiator cap and strait water in the cooling system on my 09 YZ450F. Before my bike would over heat almost instantly on some gnarly single track by my house, it doesn't help that I run stock gearing. Anyways I installed the pump and I rode for an hour hard and slow on the same stuff and it never overheat. Better then I expected!
