Yes, if you can.

OK from left to right centres 71mm middle 107mm then 71mm.Centres from 1-4, 248mm.

Looks like cbr600rr 2007 too bihe - 38mm

CBR600RR 2005 Throttle Body Venturi Size - 40mm

Still looking for 32mm venturi size.

Individual from JERNEY is good http://www.jenvey.co.uk/~WhyJDL.htm, but too expensive for me include other required modifications.

Parus, why not just use the nc29 carbs, just blank off the passages you don't need and mount some injectors to it??

For the basics all you really need is a throttle valve and a suitable place to mount the injector. The rest of the system should be no problems.

How about some tb's off a suzuki GSR400? Gpoing cheap on yahoo Japan:

The latest CB400sf is injected and learner legal in Australia, which means wait a while and I am sure a set of injectors and ignition for it will come up for sale.

Apparently it is called an NC42 or Revo

The appropriate throttle bodies is the half of problem - camshaft position sensor also need to be mounted.

Thank for the advice - it should be good idea to use GSR400 throttle bodies.

I'm not going to do it this year - as far as I'm not going to sell my 400cc for ever - I can wait, but I don't see cb400sf very popular and I don't think we can expect some of them will broken nearest feature. So, for not just collect information which donor throttle bodies I can use for conversion.
