Mikuni Main Jets

5.0 out of 5 stars 1 Customer Reviews

Mikuni main jets are available in a wide range of sizes to accommodate your exhaust flow volume requirements. Standard tuning seldom needs more than small adjustments to accommodate a wide range of engine setups. One of the more common required changes is the main jet size. Install Mikuni main jets when you are ready to re-tune and get the most out of your engine.
