    FMF exhaust on CRF100F

    by toad6301 » Thu Feb 14, 2013 2:33 am

    Installed a FMF Powercore 4 exhaust system
    on my son's 2005 CRF100F and was very
    pleased with the result. His comment was
    "COOL" and a big smile after riding it and
    opening it up. It looks and sounds great in
    my opinion and of course it BREATHS easier
    and noticeably runs better. All in all happy,
    Happy, HAPPY.

    Now you need to re-jet the 100 for added power and much better throttle response.

    Any 125 will teach him to ride and use that clutch properly.
