taffy

There isn't an aftermarket water pump for a CR500. Why does your friend think he needs one?

same Taffy from Thumpertalk waaay back in its inception?

I thought the same about the 250 but never did look into it much.
I am pretty sure the pump volume and flows will be different, since the suction and disharge lines are bigger on the 500.

I carefully radius all the sharp edges, open up the suction side slightly, with smooth corners, and remove and casting imperfections without changing the shape of the volute, or the volume especially on the discharge side of the pump.

Centrifugal pumps turn velocity into pressure, and volume CC of the pump and especially the discharge side, changes the pressure / flow out of the pump.
By design the discharge must be smaller than the suction side, so I only clean up the discharge, I do not hog it out. The discharge side is one of those situations where small ports is better than big ports

I'll post up pics on the next waterpump I modify

yep dude,ime the same taffy

the reason i asked is because ime in the process of building a 500 af showbike and wanted a trick looking waterpump cover to bling up the motor a little more than ime doing at the moment

carefull what you say about blingers. this one would rip your cr500 a new ass hole. would make mine look stupid also

tripple cylinder blinger that would do alot of ass kicking

I like bling, don't give a bling what anybody thinks of my bling thing, if its a problem they can lick my blingless ring....

for dunes its different, if someone has a shiny bike in the bush they dont ride....
