PowerFlow Throttle Body Kit by Twin Air®. Get faster, smoother throttle response where you need it most. Installed in your throttle body’s Venturi tube, the precision-engineered sleeve reduces the diameter and accelerates the velocity of your air-fuel mix. Add the thinner butterfly valve and less obstructive shaft, and you’ve got faster, more even throttle response through low- and mid-range. For better top-end throttle response (90-100% open throttle position), use the kit’s larger butterfly valve without the sleeve.
In 1972, the motocross world was given a historic boost by a revolutionary product: a laminated, dual-foam air filter that, when soaked in a special oil, allowed free airflow into the carburetor while keeping dirt, grime, sand and water out of it. It was effective, durable, washable and reusable. It took off, and the little start-up company that invented it, called Twin Air®, hasn’t stopped ever since. Evolving continually with motorcycle design and technology, Twin Air filters and accessories have stayed ahead of the competition for half a century. Today they are available for all Motocross and ATV vehicles, and distributed worldwide.
