BEGI 2025 FPR need advice, strange buzz
I need your advice regarding strange buzz in my BEGI 2025 FPR. At the beginning it worked perfectly but after 7 hours of use it started to buzz. Engine rpm decreases to 6250. But after some minutes it reaches 8200 rpm. It fluctuates. I use sea doo stock ecu, riva 50 lb injectors and ET 68-140 XLE super charger. After buzz appeared my afr gauge shows 11,7 for idle, in mid range 12,6 and wot very very rich aprx.10,1. I would appreciate for your advice.
