With the BBR Tuning Racing Series DIO Cylinder Body & Reed Assembly you’ll get the power and speed your build’s been looking for. A ported cylinder body with a high performance reed valve intake system, this race assembly was made for race engines in mind. Unlike other cylinders, the BBR Tuning Racing Series DIO Cylinder Body is ported to allow maximum fuel and air mixing within your motor. The exhaust port can fit nearly any performance muffler as well as any stock exhaust muffler you want to run, which the intake port is specifically designed to accept the reed valve assembly included with this kit. With the BBR Tuning 21mm OKO High Performance Carburetor and Velocity Stack you’re guaranteed even more power and much better throttle response than any carburetor you’ve run on your motorized bike before! With its “D” slide technology and simple, effective jetting, air flow and fuel atomization increases for a smoother and faster ride. Package includes: Modified BBR Tuning Racing Series DIO Cylinder Body BBR Tuning Racing Series 6 Flap Reed Assembly 1x BBR Tuning 21mm OKO High Performance Carburetor Manifold 1x BBR Tuning 21mm OKO High Performance Carburetor Manifold Velocity Stack space 1x Angled throttle cable retainer 1x Slow Jet 1x Main Jet 1x Length of throttle cable Note: There is gap between the reed block and BBR Tuning cylinder body. Riders will need to seal that gap with a gasket or heat-resistant seal in order to keep air from escaping from your reed assembly and cylinder. Review: Tons of Torque. - Now my bike goes up hills way better, and has better mid range torque. The Carburetor is great for adjustment and for perfect idling speeds. Mine did not come with an extra head gasket or bottom cylinder gasket. Make sure that the side port is plugged on the reed valve. This is the largest moped reed valve I've seen. The air filter appears to be 2 inches wide inside. It goes faster downhill than I'm comfortable with. I felt like if I didn't hold back, I wouldn't be able to stop, so I let off at 33MPH. It even made it to the top of the really steep hills. Review: Fast Shipping - Excelente ítem.
