Frequently Asked Questions
Will this stator fit without any modification?
Yes, this coil mounts on the original baseplate in place of the factory unit for the listed Kawasaki KX 125 and Yamaha YZ 125 applications, with wiring connected by soldering to your existing loom.
What is included in the box?
One replacement stator coil pack, ready to mount to your existing baseplate.
How do I know my old stator has failed?
Common signs include no spark, a weak or intermittent spark, or the engine cutting out once warm - test the coil resistance against the values above to confirm.
Does fitting this coil require soldering?
Yes, the original wiring loom is cut close to the old coil and the new coil's leads are soldered on and insulated with heat shrink, as this coil is supplied without a moulded connector.
