Yamaha Banshee 350 Keihin 38mm PWK Carbs (Pair) Airstriker Carb. These Keihin 38mm PWK QAS (Air Strikers) have wings on the intake bell to provide a stronger signal to the pilot jet and needle jet.
This provides better low end transition, these work great on larger cc dune and trail motors looking for a better bottom end mid range with no loss in top end. I highly tuning the carb prior to installation as it comes with standard jetting as stated. #165 / #175 Mains, and #45 / #55 Pilots.
