This dual-tooth gear — 28 teeth on the larger face and 13 teeth on the smaller — acts as an intermediate transfer gear between the balance shaft gear train and the e-starter reduction gear, also playing a role in the E-starter drive chain. A worn or damaged idle gear causes starting difficulties, gear noise at idle and low RPM, and can ultimately result in the e-starter reduction gear failing to disengage correctly after start.\u003c\/p\u003e\n\u003cp\u003eCompatible with all Rotax 125 MAX EVO variants: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO, Mini MAX EVO, Micro MAX EVO\u003c\/strong\u003e.
