The Dasa carb modification is designed to give you added horsepower as well as improved throttle response. We bore your stock carb to 43.25mm and add a new billet venturi ring. We also modify your accelerator pump in order to improve the throttle response. Improves horsepower by 2-3HP. Send us your carb and we will do the rest!
**Stock carbs on the 2004-05 TRX450 cannot be modified - Must be CRF carb**
