air cooled-liquid cooled conversion

hi all,was thinking of floggin the runner as the engine casings cracked,been offered cheap sr125 casings,was wondering what i would need to do a liquid cooled conversion?is it simple as buying a water pump kit and fitting it?
or do the casings need to be machined?any info would be great,cheers lads

 

the cases have to machined to take the waterpump.

 

i believe ben has done this??? ask him lol

sam :nerd:

 

yes, ben did use AC cases and machine them, but i beleive this was a nightmare job.

 

ah bugger,i could get it done if i knew exactly what had to be done,is there a electric waterpump from a car i could use?or aftermarket electric pump?
