For the 1936 season all single-cylinder engines were vertically situated in the frame, whereas previous models were fitted with inclined engines. The models made for the 1936 season are as outlined in the table below:

G2 models. Basically the same as model F4, made in 1934 (see previous chapter). Coil ignition fitted; Burman four-speed H.P.-type gearbox.
G2M models. The same as the G2 model, with the exception that a magneto was used in place of coil ignition.
Model G3. Hairpin valve-springs were introduced.
Model G80. This is basically the same as the 350-c.c. engine, but the O.H.V, rocker-gear is positively lubricated from the oil pump.
Model D5. This has an improved side-valve engine with detachable cylinder-head. A medium weight C.P.-type gearbox was fitted and is the same as 1934 models.
Model X4. Basically
the same as previous models, but with changes in the connecting-rods
and big-end assembly. Forked-type connecting-rods were first introduced
for this season. Lubrication details for both gearbox and engine are as
for 1939 models.

Dry-sump lubrication is used on all models
similar to earlier engines. Side-valve engines have
detachable cylinder-heads. A four-speed gearbox with
positive foot-change is used on all these machines.
