Might be a silly question but

running st170 with st170 manfold and r6,s spaced to fit
now I have to mess about with fuel rail making sure of no leaks and the throttle butterflies ive already done


silly question ---- I have the standard st injectors in the rail sat on the manifold already why should I not just use them no fab required sized for my engine in oe place for atomisation ???? or do I need to use the injectors on the throttle bodys and rejet as required ????

You can use either. But the st ones might flow more?

I had st injectors on my silvertop but went with hayabusa ones on the blacktop. Both worked fine.

As for rejet, there are no jets? Do you mean remap? If you are changing anything from std it will need mapping.

just thinking can i use the injectors standard or do i have to use the injectors on the throttle bodies
it seems a lot simpler to use the st as were they are and size is right

or is there a reason some ive seen have blanked off the standard and used the bikes ????

Yes you can use the st170 injectors if you want.

Basically you can use either. It depends on what will suit you best really as both will work.

I found the bike ones work better for my set up but that is with a manifold matched to the inlet and bodies. If you have an st then the st setup should work well so no reason not to use it.

I used the st injectors in the standard place and just left the gsxr ones in the TB's not wired up...
