Hi, wondering if anyone experiencing it too.
My 502C often stutters at only around 3900-4000rpm. Most felt at gear 1 & 2 after a stop and will come or not for the rest of the ride. Below or above that rpm range, the bike is fine.
Does anyone have the same issue?

Been back and forth to benelli dealer workshop, they felt it too and no malfunction came out from ECU scanner. Been replacing spark plug, coil, full set throttle body, fuel pump, fuel filter and sensor cleaning, but the issue remains.

Does anyone experiencing the same? Anyone know the cause and fix?

Regards,
Lukito

Hi all,
Want to update the stuttering issue. I brought the bike to Benelli Indonesia service center. They scan ECU no malfunction/error, clean throttle body all sensor including O2 sensor and EVAP canister, replace fuel filter and change spark plug using NGK CR9EK. Tuned using Sincro Multiman carburetion analyzer. Now no stuttering and acceleration is smooth as silk all across rpm :giggle:
