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.
