the SET valve is just a system to help the bike warm up quicker and run better in low RPMs, it basically improves backpressure by slightly blocking the path of your exhaust. Some people say that removing it will add more horsepower but its honestly unnecessary to remove unless it was actually sticking closed. since you have a new bike just take a cruise to the local Suzuki Dealer and have em run the code that your bike it throwing and if needed, adjust your set valve.
