Erchon Carburetor Repair Kit for Honda Rebel 250 CMX 250 CA250 (1985–2016) - Single Carb, Plunger & Jet Set

Erchon’s carburetor repair kit restores the single-carb performance of Honda Rebel 250/CMX 250/CA250 models from 1985–2016 with a complete plunger-and-diaphragm service package.

If your Rebel 250 has rough idling, poor throttle response, or fuel leaks after years of use or storage, this kit supplies the matched parts needed to rebuild the single carburetor without sourcing individual components. The package includes a plunger diaphragm assembly, accelerator pump, multiple main and pilot jet sizes, air-fuel screw with rubber ring, gaskets, springs, and a bottom shell sealing gasket — all designed to fit the original carb layout of Honda Rebel/CMX 250/CA250 models. Components are manufactured from durable materials to resist wear and impact, helping the carburetor hold tune for longer and reducing the chance of repeat visits.

How will this kit improve my Rebel 250’s running condition?

Replacing worn diaphragms, jets, and gaskets restores the carburetor’s ability to meter fuel and maintain consistent vacuum and accelerator response. You’ll typically notice smoother idle transitions, crisper throttle response, and fewer fuel leaks once installed. The kit’s matched components let the carb function like new without replacing the entire carburetor.

• New plunger diaphragm for reliable fuel delivery
• Accelerator pump assembly to eliminate hesitation
• Selection of main and pilot jets for tuning
• Sealing gaskets to stop external leaks

Will these parts fit my specific Honda model and year?

This repair kit is made specifically for the single-carburetor configuration used on Honda Rebel 250 / CMX 250 / CA250 models produced between 1985 and 2016. Each component is sized and positioned to match the original parts layout for those model years. Verify your bike uses a single carb setup before ordering to ensure compatibility.

• Compatible model range: Honda Rebel 250 / CMX 250 / CA250
• Year coverage: 1985–2016 (single-carb versions only)
• Intended for the factory single carburetor assembly
• Check part placement against your existing carb before installation

Which jets and spare parts are included for tuning and repair?

The kit provides multiple main jet sizes and two pilot jet options so you can fine-tune air-fuel ratios for altitude, modifications, or wear compensation. It also supplies the small hardware and seals commonly needed during a routine rebuild so you can complete the job in one session without scouring parts suppliers. That makes it a practical one-stop repair solution.

• Main jet sizes: 128, 130, 132, 135, 138 for tuning flexibility
• Pilot jets: #35 and #38 to adjust idle mixture
• Air-fuel screw with rubber ring for proper sealing
• Gaskets, springs, and bottom shell sealing gasket included

How durable are the kit components and what should I expect for longevity?

Parts are produced from wear-resistant materials and designed to withstand impact and typical engine vibrations, helping them last through standard riding conditions. Proper installation and avoidance of corrosive fuel or contaminants will extend service life. Regular maintenance and fuel-filtering habits will keep the rebuilt carburetor performing longer.

• Wear-resistant materials on diaphragms and seals
• Impact-resistant components reduce fracture risk during installation
• Complete set reduces need for follow-up parts purchases
• Better sealing minimizes premature leaks and failures

Who is this for: This Erchon carburetor repair kit is aimed at Rebel/CMX 250 owners, DIY mechanics, and independent shops that want a matched set of replacement parts for a single-carb rebuild. It’s useful for riders restoring older Rebels, troubleshooting poor fuel delivery, or tuning for regional altitude differences. If you prefer repairing rather than replacing the carburetor, this kit supplies the key parts and jet options to get the job done in one service session.
