3.5Bar rail pressure will allow the OEM black injectors to flow around 200bhp of power.
Obviously you will need to alter any mapping to cater, but standard fixed regulation is 3Bar IIRC.

heres an odd thing orignaly i was going to use a std black top fuel rail to make life easy but my bike itbs where in the way of the ends and the st170
rail's ends where also in the way so i choped them off and converted to hose tails both ends and was going to use a remote FPR
then i was looking at the std 2l blacktops (white injectors) FPR and its rated at 380kpa (3.8bar)
i have tig'ed a hose tail on the inlet on my std blacktop FPR realy carefuly so it didnt get hot and is still sealing ok so im going to use
that
i have not mapped my ecu yet but as both injectors are of same design im hoping it will be ok @ 3.8bar i always have the white set if thay dont
