can u change air cooled to water cooled

i was just wondering if you could change a bike such as a honda x8rs which is air cooled into a water cooled bike?
what could you use as a water pump? , think ive heard of people using oil pumps off lorries or something

can you fit a water cooled peugeot speedfight 2 cylinder on a honda x8rs? if not is there a cylider that does?

 

converting the bike to wc is easy, just put a wc lump in and mount a rad somewhere, converting the CASES to be wc is something different, bEN did it, it basically means having a waterpump mount machined in, not easy.

 

or you can completely make your own by knocking the cooling fins off, getting a water jacket braised around the barrel, having the head machined and fitting an electronic waterpump.

on the other hand, its easier to stick to air cooled as there isnt very much dis-advantage.
