What reed material is better, fiberglass resin or carbon fiber?
For all-out performance carbon fiber responds quicker to different engine pressures, but is a more brittle material and (usually) fails sooner than fiberglass resin. Carbon fiber is lighter and responds quicker, thus performs better, but history has shown us the ends appear to experience damage sooner. For reliability, fiberglass resin has proven to outlast carbon fiber in durability tests. Carbon Fiber replacement reeds, like these from Carbon Tech, respond quicker than stock reeds and improve throttle response. What sleds seem to respond best to the addition of reeds or reed cages? Generally the larger engines see more of gain than do smaller ones. While Arctic Cats seem to usually respond the best as a brand, Yamaha engines seem to leave less performance on the table than do the rest when it comes to the reeds. The big-bore 800 and 900 twins from Arctic Cat (carbed versions) REALLY respond to the addition of reed cages, especially when you also gut the airbox to increase the airflow
