Planning to fit the injector to NC29 maybe next year or during the summer when I'll get second engine.
Looks like it's possible, but following question is not clear:
- which throttle body more close to NC29
- how to fit camshaft position sensor
- which ECU (CDI) better to user. All what I found for now - is Motec M400, MicroSquirt ( http://www.microsquirt.com/" onclick="window.open(this.href);return false; ) and RTD CDI (http://racetechdevelopmentsltd.tech.off ... ducts.aspx" onclick="window.open(this.href);return false;)


For current moment I'm try to collect information about any possibility. So, will be appreciate any info, picture, question and so on.


Following were used on cbr900rr, so I think I able to use same or maybe throttle body from cbr929.

98 Honda CBR900RR
gsxr600 throttle bodies
bosch fuel pump
LC-1 wide band 02
MicroSquirt CDI

CB400 efi manifold and throttle bodies would probably bolt straight onto the nc29 block.

I can't find any available for sale. The CB400 is very fresh and nobody brake it now.

1. Crank modulator should be changes to following.

There is on the picture one with 32 teeth( with one tooth removed) 31-1, but maybe reasonable to increase this to 72-2 to increase data correctness. It should be hand made - no idea where I can buy one.

Still thinking how to fit camshaft position sensor...

Just a thought,I have a complete RTD setup from an 05 R6. Ask Derek at RTD if it could be made to fit your bike.

Dont know where its gone but there was a thread in the tec section about injection with loads of info about the microsquirt.
If its for a road bike it would be a very good way to go but if you are racing its prob better go the flatslide route as even if you get injection working theres still the problem of the throttle valve in the carb, meaning that flatslides will still flow more air per diameter than anything else.

I found only this topic http://www.400greybike.info/newforum/vi ... n&start=50. Michael do this, but with Motec efi. So, not too much info. Some guys in russia do this for very old bike.


Will be appreciate any information..

Could you send me any contact info ? BTW RLR offer set of EFI for NC29 without ECU for 900GBP... Little bit expensive for me...

If you can Email them ask for details of Sam bishops R6 injection set up.I have it,and also a brand new RTD programmable ignition for an NC29.The ignition is unused,I have 2. I would sell both the injection set up,and the 29 ignition.Ask for Derek,he developed the RLR setup.

I get following response about this throttle bodies from cbr929.

in side to motor is 11.5
air box side 12 inches
port hole about 12 inches


If anybody have carb and motor in garage - could you check ? Because I haven't spare motor for now..
