The injector operation is normal.
The injector atomisation cannot be verified by using simple
instrumentations. The injector is equipped with 5 nozzles that, thanks
to their position, create a jet with a taper of proximately 80°. This jet
reaches both intake valves.
NOTE - An injector having a low flow affects the max. performances
of the motorcycle.
- an injector having a scarce sealing affects above all the idling
speed and the start-up especially after stopping at warm
engine.
- In case the injector nozzles are clogged, replace the injector,
the filter and the fuel contained in the tank. Clean the system
and the tank with care.
