cheapie race / track bike wanted

hi all
we are looking for a sv650 ( minitwin)track / race prepped bike for my son to do track days on after moving up from the 125 cc.....
the reason for wanting a cheapie, is to make sure he takes to this class of riding and is competetive before we spend big money on a full race bike next season..

condition of bike not too important, but it must be straight and safe.
if you have a bike that is not track ready but its cheap, i may consider spending some money on it to get it ready.
dont mind cat c or d insurance bike, and doesnt really need v5 documents as it will never go back on the road and will be used for the track only.....so basically anything considered

would prefer the injection model, but this is also not a must...
anything considered as long as the engine runs fine..
