Morty it's probably not the greatest suggestion but me personally I think when the water pump fails on my Banshee i'll be getting a better one.
I haven't had one apart yet but does the pump consist of a pully, shaft with impella and the pump is sealed and supported by a pair of ball bearings and a set of seals ? Couldn't you just replace the bearings and seals ?
I'm just sourcing an exploded diagram now.
*edit*
No luck. I've found plenty of diagrams of engines but none of the water pump so far. I'll keep you posted if i find anything.
I haven't had any luck sorry.
The ultimate solution is replacement of the standard pump with the BZM item.
*edit AGAIN*
Maylands Performance has the complete Dreambike water pump for $35
