INJECTION SYSTEM TECHNICAL CHARACTERISTICS
INJECTION TIME (INJECTION VOLUME)
The factors for the determination of the injection time are the basic injection time that is calculated on the basis
of the r.p.m. of the engine, the opening of the accelerator and various compensations that are determined accord-
ing to signals coming from various sensors that reveal the condition of the engine and the riding conditions.
