How to Replace a Stator on a 1999 Honda CBR1100XX

The stator is an integral part of your CBR1100XX's alternator-based charging system. The stator itself is comprised of a steel ring that is tightly wrapped in copper wires that encircles the magnetic flywheel on the left side of the motor's crankshaft. An electrical current is passed through the stator, where it is manipulated by the magnetic forces generated by the spinning flywheel. If the stator's wire winding is damaged in any way, the alternator's ability to recharge your CBR's battery will be affected. Replacing the stator isn't too difficult, but being familiar with your CBR's motor and fairings is helpful.

Lift your CBR1100XX onto its centre stand. Unlock the seat latch on the left side of the tail fairing with the ignition key, then lift the seat off of the CBR's frame.

Remove the lower fairings from your CBR1100XX. Unscrew the lower fairing's bolts with a 4mm Allen wrench, then pull the fairing out from under the motorcycle.

Follow the stator's wiring from the alternator cover, located on the left side of the motor's crankcase, to the frame's seat rails. Unplug the stator's connector from the CBR's wiring harness. Pull the stator's wiring away from the frame.

Unscrew the bolts from the alternator cover, using a 5mm Allen wrench. Pull the cover off of the crankcase, using a side-to-side motion. The stator is attached to the inside of the alternator cover.

Remove the stator's wiring clamp from the inside of the alternator cover with a 10mm socket and a socket wrench. Unbolt the stator from the cover with a 5mm Allen wrench.

Remove the silicone gasket sealant from the mating surfaces of the alternator cover and the motor's crankcase with a shop towel soaked in acetone. If needed, gently scrape off any remaining sealant with a razor blade.

Bolt a new stator onto the alternator cover with a 5mm Allen wrench. Route the stator's wiring to the notch cut into the side of the cover. Press the rubber grommet attached to the wiring into the notch to seal the cover.

Coat the alternator cover's mating surface with silicone gasket sealant, then bolt the cover into place against the motor's crankcase with a 5mm Allen wrench. Route the stator's wiring to the frame's seat rails and plug it into the wiring harness.

Reinstall the lower fairings, using a 4mm Allen wrench. Lock the seat into place and remove the ignition key from the seat lock.
