LECTRONIC REVOLUTION COUNTER
If the electronic revolution counter does not work properly,
it is useful to test it. To do this, open the Active Test page
and, visually checking the revolution counter, click on the
Tacho test icon
If the test result is positive and during the test the revolution
counter does not settle around 3800÷4000, then the
instrument is faulty or the yellow-black wire carrying the
pulse is cut out; if the test result is negative the ECU
does not send a correct signal. It must be reset by clicking
on the erase icon. If, after the resetting procedure, the
error is still displayed in the electronic revolution counter,
the ECU must be replaced as described in chapter 13, in
this section.

ARBURATION
Carburation is an extremely important operation for the
motorbike to work optimally. It is greatly simplified by
using this software.
To adjust the carburation and set the CO, the following
software must be used: “Motorbike Diagnostic Software
Tool”; since there is no adjustment screw on the ECU,
adjusting the mixture is only possible by using this com-
puter programme.
