FEATURES
Aluminum cylinder construction
The
aluminum
cylinder has a special cast
liner
which
has superior heat dissipation
characteristics. Even during extended high
speed
operation
the engine operates ef-
ficiently and there is no significa
nt
loss
of
output.
Dry sump lubrication system
The dry sump system lubricates the engine
using a separate oil
tank
and feed
pump
.
After
lubricating the engine parts under
pressure. the oil is returned
to
the oil
tank
by
a scavenging pump. Consequently, loss and
overheating
of
oil is reduced because the oil
inside the crankcase is
not
agitated by the
crankshaft. Furthermore, the oil does
not
deteriorate
as
quickly
as
it
does in
ether
systems.
To make the machine
width
smaller. the oil
tank
is
built
in the frame. ln addition. the
ground clearance is made higher by the use
of
the dry sump system.
5-speed transmission
With
5-speeds.
power
is delivered efficiently
to the rear wheel, providing excellent perfor-
mance
for
ali operating conditions.
Starter eqlJipped carburetor
The carburetor on this vehicle has a separate
starter system. By merely operating the
starter (choke) lever a rich
mi
x
ture
is sllpplied
to
the engine
when
starting.
This makes starting easy even in cold
weather
.
Adjustable rear suspension
The rear spring preload can be adjusted
