Triggered by the ECU at a specific RPM point, the solenoid opens to route crankcase impulse pressure through the pressure line and hose package to the bellow, physically actuating the exhaust power valve to advance exhaust port timing. A failed solenoid causes the power valve to remain permanently closed, eliminating the top-end power step and making the engine feel flat in the upper RPM range.\u003c\/p\u003e\n\u003cp\u003eFits the Rotax 125 \u003cstrong\u003eSenior MAX EVO and Junior MAX EVO\u003c\/strong\u003e. Mounts to the solenoid mounting plate (R.651925) via two M5x16 Allen Bolts (R.840514). The solenoid receives its trigger signal from the wiring harness (R.666836) via the ECU (R.666815 Senior\/Micro or R.666813 Junior).\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e R.664630\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Rotax 125 Senior MAX EVO, Junior MAX EVO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBefore replacing the solenoid, test it with the Rotax wiring harness tester (R.276231) to confirm it is the fault source.
