Choosing parts for your GS1100LT
Keep the LT suffix: Suzuki’s parts catalog names a 1980 GS1100LT separately. Check the full code on the frame or registration rather than choosing a part simply because it says GS1100.
One carburetor kit per carb: Each 48-1413 kit services one carburetor. Order based on the number being rebuilt and verify the carburetor model and year.
Match fork and switch details: The fork-seal set is 37 × 49 × 8 mm. The ignition switch uses reference 37100-45301; compare the connector and wire layout to the original part.
