Made for riders who pay attention to the right air/fuel balance, it allows for fine-tuning the fuel flow in the carburetor circuit to adjust the mixture and engine response based on usage conditions and mechanical modifications.
Whether you are performing a bench tuning session, optimizing for the road or track, this jet fits into the toolkit of both the DIY enthusiast and the tuner. Before installation, check compatibility with your carburetor model and keep the original parts removed for comparison.
