Overview

Suzuki GSX 750E

GSX750E with a new 16-valve engine replaced the eight-valve GS750E. Even the new machine was a massive air-cooled engine, called bullet-proof by some. As for all early GSX machines, the charging system can cause problems if not maintained carefully. Even the big end bearings can wear out (after several years of usage). The exhaust side cam shaft will also wear down and need to be replaced, sooner or later.

In 1982 the third version of the GSX750E got several cosmetic and even mechanical changes. The rectangular headlight and instruments were dropped. The round headlight came back and even the meter housing got more classic look. Modified meters and various indicator lights. Oil temperature meter now as standard.

The GSX750EZ (E3) engine got hexagon bolts instead of Phillip screws. Also the clutch cover was redesigned. Turning signals attachement moved from front fork to headlight. Two signal horns instead of one. Adjustable rear shock absorbers. Modificated switches by the left handlebar. New aluminum casted brake master cylinder.

Last year with the air-cooled engine. The 1983-year's GSX750ES and GSX750EF models were air/oil-cooled.
