Set of 2 Reproduction Intake Insulators With Gaskets - 16211-283-000 - CB450K CL450K

Ships in 24 hours

Set of 2 Reproduction rubber intake insulators / rubber intake manifolds / carb holders for the Honda CB/CL450 twins from the 60's and 70's. If you've discovered cracks on your stock intake boots, it's time to replace them because they're most likely leaking air which leans out your air/fuel mixture. A quick way to check is to spray something non flammable on the boots with the engine running, if you hear a change in RPM, they are leaking for sure!

Kit Includes:

Honda part number (gasket): 16229-283-306 - Qty. 1
Honda part number (insulator): 16211-283-000 - Qty. 1

Insulator Dimensions:

I.D where carburetors mount: 42mm
I.D engine side: 33mm
Mounting hole spacing (measured center to center): 64mm
Height: 28mm

All models listed use 2 insulators. The left and right insulators are the same. Sold as a pair

These would probably also fit the CB500T (16211-375-000) but it does not share the same Honda part number, check the dimensions above.

Fits Honda:

CB450K - 1965-1974
CL450K Scrambler - 1968-1974

    Some older bikes are hampered by rubber parts like this going bad with no reproductions available. Glad these are available and fairly priced for our old Honda’s. Fit great on my 450.

    These do fit a cb500t. Excellent part and helped my engine build. Get rid of those rock hard rubbers.
