So i have a been tossing this idea around for a while. I have 2 water cooled pocket bikes and one of them has always had an issue with the internal water pump. Has anyone ever tried or considered putting an electric battery operated water pump on their water cooled bike?

I am looking at this one to put on my G2 w/ GP3 rep reverse motor.

What do you guys think?

If the pump cannot push the water like the regular pump can at high revs then Id say that may be your downfall.....if there was a way to regulate the speed of the pump with the rpms being spun youd be golden.......

One time I put a Moroso electric waterpump kit in a 78 Olds w/383 and M22 4 speed .....The waterpump couldnt keep up after the first time I whack the throttle and put the engine to 6500 rpm's for more than a quarter mile..I looked at the box and it said for competition use only meaning quarter mile only............I had to ditch the setup and go for an underdrive kit........

Good point, i had not considered the rpm difference. Maybe i need to calculate the gpm of the existing one.

well thats right but we do a moter here for this sort of thing thay use it on small boats its a lil hand sized pump it has a small cord like a throtal cable and when pulld more and more makes it work faster and it will pump the water round a high max 250cc inpeller on a boat thay are like £25 here and i think will defo work

My boat uses a vacuum activated Mikuni fuelpump to pump the water tapped off the intake manifold.........The faster it pulses the faster it pumps......

yeah see i wos more along the lines more like bigger boats but yeh sure

Put a bigger pully on the OEM pump and slow it down.
