The BBR Tuning Reed Valve Kit will have your 66/80cc or 48cc 2-stroke gas bike engine running like a top! This is a 32MM stud spacing reed valve- please check the measurement between the intake studs (center of the stud to the center of the stud). This reed valve kit works with our Flying Horse and Mega Motors 66cc and 48cc motor bicycle engines, as well as most Chinese engine kits on the market. Installation is a breeze: simply replace your existing intake manifold with the reed valve assembly, attach your carburetor to the reed's intake port, and you're done. Get an increase in bottom end torque as a smoother running throttle response with the BBR Tuning Reed Valve Kit!

Fits on 30mm Intake Manifold ports
