About the Suzuki GS550MZ
1982 Suzuki GS550MZ carburetor rebuild kits, slide diaphragms, float bowl gaskets and exhaust joint seals.
The GS550MZ appears in Suzuki’s 1982 Katana-era model range. Its distinctive model designation remains useful long after bodywork or badges have changed: the carburetor parts here identify GS550MZ 1982 . Use that full product when comparing it with other GS550 variants.
Buy the carburetor component the repair actually needs
The slide diaphragm belongs to the slide assembly; the float bowl gasket seals the joint at the bowl. A carburetor rebuild kit is a separate package whose contents need to be checked before teardown. The MZ applications below cover 1982, but they do not mean every seal, diaphragm or fuel-system part is included in one kit.

| Model | Repair part | Listed years | Before ordering |
|---|---|---|---|
| GS550MZ | Carburetor rebuild planning | 1982 | Check the service pieces included and the quantity needed before dismantling the carburetors. |
| GS550MZ | Slide diaphragm replacement | 1982 | Compare the diaphragm and slide arrangement on the fitted carburetor. |
| GS550MZ | Float bowl sealing | 1982 | Match the bowl outline and seal profile. |
| GS550MZ | Muffler joint sealing | 1982 | Check the 35 × 39.5 × 32 mm listing against the fitted exhaust joint; this is not a cylinder-head port gasket. |
The 1981 GS550T repair guide covers another model named on the shared carburetor kit. Keep the individual MZ and T applications separate, or compare all GS550 models.
Prepare for the repairGS550MZ identification checklist
Use the motorcycle’s markings, model-year paperwork and fitted components together. This checklist does not assign frame or engine serial ranges.
| Check | What to confirm |
|---|---|
| Model and year | Confirm GS550MZ and the 1982 application; cosmetic Katana parts alone do not identify the underlying motorcycle. |
| Carburetor markings | Compare the fitted carburetor assembly before relying on a shared E, L or T product. |
| Removed service part | Check diaphragm edges, bowl-gasket shape and the kit’s actual contents separately. |
| Exhaust joint | Identify the original or replacement exhaust and measure the joint being sealed. |
