    crf150f tuning question

    by yunis83 » Sun Jan 18, 2015 5:08 pm

    Hey Guys,
    New member here from Australia here, I got myself an 04 CRF150F a few weeks ago and noticed there is some bog when taking off from idle. If I snap the throttle open from Idle it will stall

    I pulled out the carb and gave it a clean. I noticed one of the previous owners have rejetted the carb.

    Main Jet: 115
    Slow Jet: 40
    Jet Needle clip position: all the way at the top (5th position)

    Mods:
    - BBR d2 Exhaust
    - Twin Air filter
    - air box mod

    My question is the bike feels like its running a little flat in first. Should I increase the size of the slow yet? and should I lower the needle clip position? or would this simply just require me playing around with the pilot screw?

    Any advice is appreciated :)
