required transmission ratio would lie between 6,48 and 6,69.
Use Table 1 and pick an appropriate combination of chain gears.
For the required transmission ratio between 6,48 and 6,69, the
chain gear matches 12/78, 12/79, 12/80, 13/85, 13/86 or 13/87
can therefore be selected.
NOTE:
To simplify changing of the transmission ratio it
is recommended to carry clutch drums with a
prefitted chain sprocket of various numbers of
teeth.
employed transmission ratio
CAUTION
WARNUNG
NOTE:
The decline of the engine speed during Kart op-
eration will be controlled by the exhaust system.
Above the engine speed of 10.500 rpm the ef-
fectiveness of the exhaust system decreases,
resulting in a big drop of performance (see

Never run the engine without load. By revving
the engine without load, speeds of above
14.000 rpm can be reached and this exces-
sive engine speed will drastically shorten the
life span of some components (conrod,
conrod bearings, etc).
