'02/'03 Kawasaki Ninja ZX-12R...rated at 165 horsepower




I machined off the flange of the manifold, the offset hole is on purpose, it better matches the bore of the t/b and allows a staight shot for the injectors to spray right at the intake valve. I plan on adding a bracket between the t/b and the manifold to give it a little more side loading strength.




Anyone have the flow numbers for the injectors used on this bike?

Hi mate, I'm using RHB52 as recomended in Joe Hailes book on turbo charging motorbikes. The specs he gives for a 1000cc are no good spec now is with R20 exhaust housing and bigger compressor wheel. The R15 housing is too small for a 1000cc bike engine and even with the R20 I had to port the waste gate to keep the boost down.


Using MS1 with v2.2 main board? MSnS for FI only to get the 12x12 table.

BFG the GSXR 750 Bodies will be fine on the RS2K.

Heard from Dean you're not scrapping the car Great News. If you want to pop down anytime and have a look at my 600 Set up your more than welcome or come along with Dean to the next Track Day

BTW, I really want to know the spacing of the zx12 ITB.

Has anyone come up with a source for injector connectors for these bike TBs? I'm using CBR TBs with Keihin injectors, but wasn't able to get the harness parts. Anyone have a source?

Check Ebay.. I see harnesses on there often...

I'm looking for a set of CBR1000XX Blackbird fuel injectors or Honda S2000 injectors...

Alfa SPICA throttle bodies. 40mm butterfly diameter. Bore centers about 9cm apart.

anyone have any info on the 02-03 YZF R1 throttle bodies? i know they are the CV style, but thats about it.

I don't know the exact specs on these, but here are the stock ITBs on a 20 valve 4age (toyota):

Iam looking for about 240 bhp.

i also use an FSE boost valve set to 42psi/3bar which gives a flow rate of 255cc/min. At 38psi it gives 250cc/min.

Any body got one like this?

has anyone of you used these TB units in:

- a siamese ports application?

- a forced induction setup (blow through the TB unit)

I have a question :
What screw i have to ajust on these ITB to balance them with a tool like carbtune : http://www.carbtune.com/
There are screws with little springs beetween the throttle bodies (3 screws in total) for ajusting the throttle angle.
And there are screws inner each body (4 screws) for adjusting a "bypass".
Which of these screws must I ajust for correct balancing ?

Thanks ?

Do someone can post a alpha-N VE/Ign table of a ITB engine here ?

Hi,

info taken from this thread..

http://www.r6messagenet.com/forums/r6-m ... ctors.html

says that the injectors for the Yamaha R6 '03-'04 have a flow rate of 235cc/min at 284kPa

And I can confirm the impedance is 13.3 Ohms
