Air-cooled to liquid cooled conversion

Hey,
I have an Air cooled piaggio engine, any ideas on how much it would cost to turn it into a fully functioning liquid cooled engine?

 

lol i wana do the opposite when i finally get a ped as think an air cooled lump is so much easier to work on and no leaks or pumps or rads to bother about plus the typhoon can run a 172 iv been told

 

Liquid cooled can be modified so much more, but the parts are more expensive.
I so badly want to get this setup:

i totally agree on both subjects, air cooled is easy to work with, but then again a bit of extra work means your bike could be faster liquid cooled beats air cooled ony day of the week, and tbh parts are hardly much more, but i always say you've got your 3 options.... cheap, reliable, fast.. pick two? if you want cheap and fast it wont be relible if you want reliable and fast it wont be cheap.. thats about it..
