I had '16 RXP 300 with stage-3-kit and Vtech tuning. No regulator. Just orginal fuel pump and 1100-injectors. I rid 50 hours with it and rebuilt engine two times because of connecting rod upper bushing and oil cooler. But I never saw any signs of running lean or detonation. The fuel is 98E here in Finland though.

If you're referring to Riva stage-3 kit than that's the 135 wheel, the XXX is 142.

May i ask what was the symptoms of upper bearing failure? Knocking in engine? Oil pressure light?
Cheers
