Any one got any info about theese injectors ??or were I can find it .
Got the throttle bodies from EBay .

It's from a 2002/03 Yamaha R1 , according to the manual they are
INP-731/4 from NIPPON INJECTOR .

They also got some # on the side of the injectors , CDH210 .

Fuel pressure 284 kPa (2.84 kg/cm2, 40.4 psi)( fuel rail pressure )

Injectors resistace = 14.7 ohm .

That's all info I got ,need more

If working backward , they shuld have a flow rate off 22 (lbs/hr) ?? ,but .......
Yamaha part# 5PW-13761-00-00 .

Nippon injectors I've seen have the flow in the second part number - so yours are likely 210cc flow at unknown pressure (2.5 bar?). You could check this against others at the dealer or have a shop flow them. Sorry I don't have more for you.
