CBX Master Carb Kit
This kit is proprietary to Randakk's you won't find this available anywhere else at any price.
WORLD'S BEST CBX KIT!
Beautifully Restored CBX Carbs by Leon Summers of Los Gatos, CA (using parts from Randakk's)
"Hi Randall, Wanted to say how very happy I am with the CBX carb overhaul kit I recently purchased from you. Your delivery was very prompt - within 2 days from USA to Australia is pretty good!! - and all components of the kit were present, of excellent quality, very well packaged and in very sensible package "groupings" so as to allow this CBX carb 'newbie' to ultimately make sense of it all.
Due this being an "educational project" for me and having to diagnose and fix many niggling problems due to my own inexperience, I had to join the pairs and rack of carbs I would say at least 10-15 times. I believe the fact that the carb rack successfully went apart and together so many times with absolutely no hint of a leak from the rack on the final on-bench leak test speaks volumes for the quality and durability of your product. Excellent product and you can count me in as one very satisfied customer. Keep up the good work. Kind Regards."

Randakk's considers CBX carbs to be works of industrial art ...truly amazing carbs. Simply stunning examples of very intricate die casting! Here's another Randakk exclusive item designed to help you put your CBX carbs in top working order. Randakk's CBX Master Carb Overhaul Kit(R) includes everything you need (and nothing you don't!) for a comprehensive CBX carb overhaul.
Kit is proprietary to Randakk's...you won't find this available anywhere else at any price. Randakk's sourced the best available parts from 3 continents and combined them in a unique combination that represents real value. Kit is appropriate for any 1979 - 1982 CBX with original carbs.
Unlike other kits on the market, Randakk's kit even includes those pesky carburetor body side-to-side sealing o-rings that seem to give so much trouble on units that have been parked for awhile (details below).
Note: The round o-rings in each of my Master Kits are made of Viton rather than ordinary nitrile (Buna-N) as found in other aftermarket carb kits. Viton is superior to nitrile in terms of:
- Heat tolerance (400 degrees F vs. 250 degrees F)
- Compression set
Did you know that one good case of severe engine overheating can ruin the carb o-rings found in ordinary kits? Randakk o-rings are the best available! See Viton Proof here.
Also, Randakk's o-ring sizes are precise. They're equivalent to the exact sizes specified by Honda for each fitment. Not "close-enough" sizes as in many of the other aftermarket kits I've evaluated.Contents of Randakk's CBX Master Carb Overhaul Kit(R)
Also includes 12 high quality panhead screws for securing choke butterflies
Unlike ordinary aftermarket kits, each Randakk kit provides everything listed for all 6 carbs plus other items required for splitting and rejoining the carbs to replace the cross carb fuel transfer tubes as well as the float bowl vent circuits. Randakk's even includes rebuild kits for the air cut-off valve and accelerator valve. Best of all, Randakk's offers you the opportunity to include a terrific manual by friend, Mike Nixon, to guide you through the rebuild process.
Only the highest quality items are included. The kit has been thoroughly tested. Collection represents the best value available in the market. Trust Randakk's, you'll need everything in this kit to do a proper overhaul of your carbs.

Randakk's also recommends that you refer to the official Honda Factory Workshop Manual. There is some critical information there on rejoining and aligning the carb bodies to prevent binding of the throttle and choke shafts...very important! >Randakk's Master Kit includes all the o-rings needed for renewing the fuel transfer tubes (main and accelerator) as well as the air cut-off circuit tube connectors.
Randakk's also includea 12 high quality, plated M3 x 6mm (0.5 pitch) panhead screws for securing the choke butterflies. The choke butterflies must be removed during disassembly of CBX carbs to renew the side-to-side transfer o-rings. The staked OEM choke butterfly screws are very difficult to re-use. You will need to use some medium strength Lock-Tite to secure my screws.
Note: No jets or jet needles are supplied with kit. These can normally be cleaned and re-used. Aftermarket needles are not sized as accurately as the OEM needles and may introduce lean / rich problems where none existed. Unless your needles are worn or bent, Randakk's recommends reusing them. If you try to buy jet needles from Honda, you'll discover that they are only available as a set which includes the CV slide, cap and jet needle. The price will make you faint! If you need jets, buy aftermarket kits such as those from K&L or spring for the genuine Honda bits.
No float valve/seat assemblies are included in the kit. Many aftermarket rebuild kits include float valve/seat assemblies of dubious quality. There have been many problems with these aftermarket items. Most related to the aftermarket float needles being incorrectly sized (too short) resulting in unreliable (or nonexistent) fuel shutoff. Some are OK. The rubber tips and seats on the OEM item will last nearly forever and can usually be cleaned and reused. If you decide to reuse your existing float assemblies, be sure to remove and clean the small fuel strainer beneath the float seat. We're keeping the cost down and giving you a choice on what to buy if you think new ones are needed.
If you need new float valve/seat assemblies, you can buy the OEM item and not have a worry. This way you'll also get new fuel inlet screens (the plastic strainers installed below each float valve). The Honda part number is #16011-422-004. You will need to order 6 of these. Or, take a slight gamble and go with aftermarket float valve/seat assemblies which are available at reasonable cost from numerous suppliers. When you use aftermarket float valve/seat assemblies you will need to carefully remove, clean and reuse your existing fuel inlet screens.
Randakk's CBX Master Carb Overhaul Kit(R) includes 106 total pieces (count the air cutoff overhaul kit and accelerator pump kit as only "1" piece each in total count even though each actually has a diaphragm, spring, seal, boot, etc.).
Considerable skill is required to install this high quality kit correctly. Since Randakk's cannot control this important variable, there is no warranty. Rest assured that they are of the highest quality materials and workmanship. Each kit has been carefully packed and inspected to ensure that all items are included.
Warning: Please open the package very carefully upon arrival. Many of the parts are very small so take appropriate precautions. If you chose to open the package in the dark over your gravel driveway, after 1 or 12 beers, please don't later complain that you are a "few o-rings short." Seriously, do be careful when you open the package!
