There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

A: Your 2016 Yamaha YZ450F is a fuel injected machine and does not have jets. However a fuel programmer would be recommended for optimum performance when installing a complete system. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: Your main jet is too small, I would go up one size at a time until the problem is resolved.

A: You will have to pull one or both of the pilot jets out so that you can verify the correct style of pilot jet. You can refer to this link for help identifying them:
