Hi all.

I have acquired a set of used 39mm FCRs for my '93 CBR 900, the carbs have a TPS but I don't know for sure what bike they were on originally.

Anyway I would like some advice on a jetting baseline before I install them. The brass in there currently is:

170 Main
52 Pilot
EMP needle on 3rd clip
200 Main Air Jet
Adjustable Pilot Air Jet at 1.5 turns out.

Will this work? Anybody have a set of properly sorted FCRs on their early blade?

Thanks in advance for any help.
