Title: Main Jets/Pilot Jets Wanted
Post by: Dresda 500 on July 06, 2026, 05:48:29 PM

Hi all
I have searched a lot for these but it seems that stock has dried up.
CB500 running Delkevic 4 into 1 and Ramair foam pods.
There is little room for filters, just stone guards are a possibility, should get away with cut down foam pods.
From what I’ve researched I require 115-125 mains and 40-45 pilots.
Carbs are 649A
Any advice is welcome.

Got hold of some some 120’s/40’s to try.

I think you'll be too rich.
I have the same carbs on my CB500 K1 but I also have a Yoshimura 553 big bore kit, street cam, S&W valve springs and pod filters and a custom 4 into 1 pipe.

I'm jetted at 42 and 115 with the idle air screw set around 2 turns out.

Thanks for the info. It’s all built up waiting for a test ride.
I’ll let you know how it runs.
