Coolant; Checking The Fl Oat Level - Beta RR 250 Owner's Manual

3
CHECKING THE FLOAT LEVEL
Remove the carburettor and the fl oat cham-
ber. Keep the carburetor on a 60° approx.
incline, so that fl oat leans on the needle
valve without pressing it.
In this position the fl oat edge should be
parallel with the fl oat chamber sealing
surface (see fi gure).
If the fl oat height does not correspond to
the nominal value, check the fl oat needle
valve and if necessary replace it.
If the needle valve is in working order,
adjust the fl oat height by bending fl oat
lever 1.
Assemble the carburetor tank, assemble
the carburetor and check idling.

COOLANT

A
The level of the coolant must be checked
when the engine is cold. Use the following
procedure:
•Unscrew cap A and visually check the
level of the liquid. When the engine is
cold, the radiator fi ns should be immersed
in the liquid for about 10 mm.
•Top up if the coolant does not cover the
radiator fi ns (see chart on page 28).
The capacity of the circuit is shown in the
table on page 20.
WARNING
To avoid scalds, never unscrew the radiator
fi ller cap when the engine is hot.
