About the Suzuki GS400

Restoration parts for the early GS400 twin, with separate E, L and S applications.

Suzuki Motorcycle Logo

Suzuki’s archive dates the original GS400 to 1976, with an air-cooled, DOHC two-cylinder engine. The cast-wheel GS400E followed in 1978. Later uses of the GS400 name make the complete designation and year essential when selecting restoration parts.

Early GS400 engine and fork parts; E, L and S service parts

The early engine gasket set here fits GS400 1977–1979, while the fork seals fit GS400 1977–1978. The E, L and S collections include later carburetor, control and electrical parts with their own ranges. In particular, the S bowl-gasket entry covers 1980–1981 and 1984–1986, leaving 1982–1983 unconfirmed for that part. Other suffixes also appear on individual products in the wider parent range.

Does this repair use the same carburetor parts for every GS400 year?
