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

Erchon Carburetor Repair Kit is a complete replacement parts set designed to restore the single-carburetor system on Honda Rebel 250/CMX 250/CA250 motorcycles (1985–2016), including plunger and accelerator pump assemblies plus multiple jet options.

This professional-grade kit gathers the common wear pieces you need to rebuild a single carburetor on Rebel 250 models spanning 1985–2016. Every included component is matched to the single-carb configuration used on these Hondas so you can address leaks, poor throttle response, or fuel delivery inconsistencies without hunting down individual parts. Components use durable, impact- and wear-resistant materials intended to extend service life and return the carburetor to consistent performance.

What exactly is included and why each part matters?

The kit contains a plunger diaphragm assembly, accelerator pump assembly, air–fuel ratio screw with rubber ring, gaskets and springs, a bottom shell sealing gasket, plus a selection of main and pilot jets. These pieces are the ones most likely to fail from age, ethanol fuel exposure, or varnish build-up.

• Plunger diaphragm and accelerator pump: restore proper fuel metering under throttle changes.
• Air–fuel screw and rubber ring: re-seal and fine-tune idling mixture.
• Assorted main jets (128/130/132/135/138) and pilot jets (35#, 38#): allow tuning for different elevation, fuel, and modifications.
• Gaskets, springs, and bottom shell seal: stop leaks and re-establish correct mechanical clearances.

How does this kit fit my 1985–2016 Honda Rebel 250?

Parts in this Erchon kit are specified for the single-carburetor versions used across the CMX 250/CA250/Rebel 250 model years indicated. The kit is intended as a direct-match repair package, so components align with the OEM layout and attachment points used on these bikes.

• Designed for single-carb variants of Rebel 250 / CMX 250 / CA250 models.
• Parts sized and shaped to match factory mounting and sealing surfaces.
• No need to source separate jets or diaphragms for common rebuilds.

Can this kit help when my bike has poor idle or bogging on throttle?

Yes — replacing worn diaphragms, jets, and seals often cures symptoms like unstable idle, hesitation, or surging. The accelerator pump and plunger assembly restore correct transient fuel delivery, while jet options let you correct mixture for your conditions.

• New accelerator pump improves mid-throttle responsiveness.
• Fresh pilot jet and air–fuel screw sealing stabilize idle and low-speed throttle.
• Main jet selection provides tuning range for elevation or aftermarket modifications.

How durable are the replacement parts and what maintenance should I expect?

Erchon parts are produced from wear-resistant materials to handle normal operating stresses and fuel exposure. While the kit extends the service life of a carburetor, routine inspection and occasional cleaning remain recommended, especially if the motorcycle sits unused or runs ethanol-blended fuels.

• Impact- and wear-resistant components to reduce premature failure.
• Gaskets and rubber rings replace hardened seals that commonly cause leaks.
• Periodic cleaning and proper fuel storage will maximize longevity.

Who is this for: This Erchon carburetor repair kit is aimed at DIY mechanics, motorcycle restorers, and workshop technicians working on Honda Rebel 250 / CMX 250 / CA250 single-carb models made between 1985 and 2016. It’s a practical one-stop kit when the carburetor needs a refresh or when tuning jets for altitude, fuel type, or mild engine modifications.
