Method & assumptions

Manufacturer chart lookup ONLY for NX Conventional Stage Six 4150 / 4500 plate systems. These pairs are not motorcycle nozzle, spraybar, dry-system, or other-brand recommendations. No interpolation or bottle-pressure scaling is applied. The chart does not specify bottle pressure; verify the current kit instructions and operating conditions with NX before use. Jet values are nominal thousandths of an inch and use the manufacturer’s jet series. Source: NX Conventional Plate Jetting Chart.
