On my MC21, I’ve always had to feather the clutch to pull away from a stop. The power is poor and the engine bogs until the rpms rise then it's fine. Midrange and top end, it pulls like a train.
It has a drilled airbox, Tyga pipes and #40 pilot jets, air screws out 1 1/2 turns. When it had stock #38 pilot jets it was even worse.
Is it a symptom of a lean condition in the idle fuel circuit or is this normal bottom end performance for an MC21?
