    Change main jet first (before needle)

    Put this on my 2007 crf250x used 160 main, used the 42 it was same as stock but put new one anyway The red needle on 5th from top would only fit once the main jet was changed (stock was 130). did modified air box mod, removed screen on air filter, twin air filter, removed baffle from exhaust pipe. Also boysen quick shot 3. also put quick adjust fuel screw. turned fuel screw 2 1/2 out. took better part of a hot august day to complete. It was well worth the time and money. Took bike out around yard front tire comes up easier, more bottom end power and less bog look forward to a long ride. make sure to read all of instructions as my carb was an alternate instruction

    JD Jetting Power Surge 6X Fuel Injection Tuner

    RANDY in FL

    Easy to operate!

    I installed this one a 2014 Husky FC 450. It lets me richen or lean the fuel mixture anywhere in the rev range that I want. That allows me to move the power delivery where I want it. No maps and no computer needed. Changes take just seconds to do. If you don't like what you did just try another setting. It's really that simple!
