Fuel Injector Servicing

hey guys, does anyone know a decent place in Melbourne for fuel injector serving? (ultrasonic clean, flow test, etc?)
 
it's not technically for my MR2 but i figure as its a bit of a specialist thing these places may do injectors of all sizes. I'm looking at pulling the top fuel rail off my bike to get it and 4 of the injectors cleaned. I have been trying injector cleaner but it's hard to get fuel through them consistently (only use them at open throttle which has legal implications) and i dont want to clean three and run lean on one cylinder.
