    Easy

    Used on a KLR650. Power increase was nominal but fuel efficiency was increased and helped eliminate "popping" with my aftermarket Vance and Hines exhaust. Very user friendly with easy to follow instructions. You dont have to completely remove the carb for this upgrade but you really should so it can be properly cleaned at the same time.

    FMF JET KIT

    Put this on an XR650l and it worked great first try. Major increase in performance. Well worth the 55.00 dollars.

    Kit fits as advertised.

    I had a professional mechanic rebuild my carbs and all the parts fit and the kit was complete. Bike runs like new (a 1980 Suzuki GS 750 EX)
