    Air/fuel rate for CBR600F3?

    I have a 98 CBR600F3 and I need to set the air/fuel mix and don't know what the stock setting is?

    Dynojet pdf says 1/2 turn, I found a thread on a CBR site that said 1.5 turns and the service guy at my local stealer-ship said 3 turns. I only want to do this once (if possible), so anyone know the stock setting? I don't have a manual, thanks.

    I dont' know what your bike truly calls for , but 3 turns sounds incorrect ,,
    somewhere around 1.5 sounds a bit closer,,..(stock correct? )

    The manual for a 97 has the 49 state at 1-2/4 turns out. (exactly as written in the manual)

    I suggest PMing TLRMan (Mark). The guy's a wiz with carbs. He did an awesome job w/ my 900RR.

    Thanks, pm sent.

    So does that mean 1 and a half turns (2/4 being the same as a half) or 1/4 to 2/4 of a turn (like a range) or 1 turn to 2/4 of a turn (again, a range but with a weird fraction)?

    Never got the PM, but they are set up to be lean stock, I usually will start at 2 to 2 1/2, and will adjust the carbs individually when running. Airfilter and exhaust assumed as stock?

    1 1/2 turns out is correct (3 wrist turns of 1/2 turn each is what your mechanic is referring to)
