Honda Carb Kit CM/CB400-450 Twins, CX500, GL500-650 - Exclusive Kit

Carb Kit

Both Carbs

This kit will contain the parts for BOTH Carbs for some models that are hard to find carb good kits for typically.
We have assembled these kits using the same parts we offer separately.
All the rubber parts are a NBR Buna rubber or Viton to work more effectively with new fuels that contain a lot of alcohol additives.
Kits are available with all the screws for top covers, float bowls, accelerator pump cap, and air cut-off valve caps.
The ONLY difference between the two purchasable options below is the type of float needle they come with. This is important to verify due to the fact you can find bikes that have the earlier carbs installed on the later model years or visa-versa. Closeups of the VERY different float needle versions are pictured next to each purchase option.

We can also supply some kits that will do the job originally designed for other models. If you look at the pictures
of the following models, you will see they have most all the important parts needed to
rebuild the carbs on any of the bikes above.

Basically, the major difference in the kits below besides jet sizes and the float needles.
All of the bikes above use one of two different float needles based on the year range. Honda's
made '78-'79 have a black fiber float with stainless bracket and use the needle with the spring clip
and '80-'85 models use a all plastic white float that is non adjustable and use the needle with notched top. Keep in mind the white floats turn a pale shade of yellow all the way to dark browm with age.
Take a look at the pictures below to see this up close.

So with this knowledge you can use the pictures below to choose a kit that has the needle you need for your model
Then the next thing to check is the jets. Don't be too worried if the jet sizes are not exact for your specific bike,
if they are it is a bonus, if not most jets can be re-used and not hinder your rebuild. ALL models use the same air screw,
the same float bowl gasket, and the same o-rings. This makes the jets and the needle the main things to identify.
You will also note we included the size of the jets that come with the kit to make your choice even easier.

Once you find the kit you want, go back to the Honda carb kit page and order the make/model/ and year that the kit
was originally designed for. Also note, all kits are sold separately so order 2 kits if you are fixing both carbs.

Air cut-off valves and accelerator pump kits are always sold separately for ALL kits and can be ordered from
our "Miscellaneous Carb Parts page" if you require them.
