Reedy have announced the release of three all-new carburetor venturis for the 121VR series engine. These new venturis are available in 5.0mm, 5.5mm, and 6.0mm and serve as a useful fine tuning option for serious nitro racers. Smaller venturis help increase fuel mileage, which translates into longer run times between pit stops. Reducing the number of pit stops over the course of a main event could mean the difference between winning and finishing off the podium. They are also an effective way to reduce power output and improve drivability on low-grip or blown-out track surfaces. Each restrictor is sold individually and features laser etching of the venturis’ size for easy identification.
