APRILIA RST mille Futura 2001 Service Manual page 154

FUEL SYSTEM
A parameter appears at the top of the display in
percentage form, which should not be compared to the
CO value reading provided by the exhaust gas
analyzer (1).
Use the UP and DOWN arrows to change the
instrument parameter: if the value increases, the
injection time also increases, providing a richer blend
and thus increasing the value of CO; vice-versa, if the
parameter is reduced, the CO value falls.
WARNING
Slowly change the parameter on the instrument (no
more than 2 or 3 pulses at a time), and wait for the
CO value to stabilize on the exhaust gas analyzer (1).
Use the vehicle exhaust/tester (2) connection lines of
suitable length (2'-3').
Check the CO on both exhausts, and make sure that
the maximum difference is no greater than 1%.
NOTE
If you are unable to obtain the prescribed CO
values, replace the spark plugs, see 2.7 (SPARK
PLUGS).
