    2004 CRF150F jetting

    by drdave69 » Sat Feb 06, 2016 7:19 am

    I just installed my 'power up kit' in the carb. I used the 108 main jet and set the needle in the second slot (from top). Also installed the t-handle adjustment screw (1-1/2 turns out). Idle seems to be slightly erratic and engine pops on deccel. Is there anything that I need to alter to get this working better?

    If the power up kit you installed in the CRF's Only kit you need to install the needle on the middle clip position. Also, make sure the jets are seated correctly. Lastly, when installing the fuel screw make sure you install it correctly. There's a washer, o-ring, and spring. You need to make sure these were installed correctly and only one of each is installed.
