I have a pair of GSXR600 throttle bodies sets to assist in an economical conversion to fuel injection of the A series for the Midas.
1 set have already been separated, just need a little bit of final preparation, with a set of brand new cone filters. Complete with injectors and fuel rail £80.
1 set is as from bike, untouched, complete with injectors and fuel rail. £60
Plenty of info on the internet on how to do this conversion cheaply. Especially good now that siamese code is available for the 5 port.
