Carburetor Insulator – NX650 Dominator RD08 | 16211-MAN-620

This is a premium replacement Carburetor Insulator (also known as the intake manifold joint or carb boot) for the Honda NX650 Dominator RD08. This part is an exact-fit replica of the original, unrestricted Honda part number 16211-MAN-620 and acts as the definitive full-power upgrade for the restricted 16211-MAN-740. The carburetor boot is absolutely critical for optimal single-cylinder engine performance, acting as the flexible, airtight seal between your carburetor and the cylinder head. The original factory rubber dries out, hardens, and degrades over time—causing vacuum leaks, erratic idling, and lean-running performance issues. With this replica, vacuum leaks are a thing of the past.

The Unrestricted “Full Power” Advantage
If your RD08 Dominator feels sluggish or was originally imported from a market with tiered licensing (like Germany), it may still be choked by a restricted factory intake manifold (such as the 16211-MAN-740). Upgrading to this open-bore 620 style insulator is the definitive, hardware-level method to restore or maintain your bike’s true 44 horsepower factory output.

Not only is this carburetor insulator a precise replacement for your motorcycle, but it is also backed by our Lifetime Guarantee.
