I have the FCR 39 carb (with EMP needle?)....I just installed 416 with port/polish and 1mm OS intake valves and HRC cam. I know I have to rejet, my question is are the pilot, needle and main jets the same as the original Keihn carb? Can I go down to the Honda dealer and get these parts or are they special order from Keihn? For the guys with the same set up, just to get me in the ballpark, what jets are you running? Thanks very much for your help, I hope to feel a good improvement in speed.
Main jets are the same series (#357 but commonly called "hex jets"). Jet needles are different (I might call the EMP needle "middle of the road" as far as rich/lean. The E, M, and P each designate a different dimension of the needle). Pilot jets are different (FCRs use a series 25).
Main jets are everywhere.
Series 25 pilot jets might be found locally at a tuning shop.
If you need a different needle, you will probably have to go to Sudco.
