YZ250-YZ250X Electric starter - Installation guide
If you are running the starter without charging system, you will need to put the supplied steel shim with
two gaskets. To make the installation easier, you can silicone the two gaskets on each side of the steel
shim so they all stay together.
Unbolt the small gear cap of the starter housing with a 4mm allen and remove the two starter gears.
Install the housing on the engine with the proper gasket and ensure the housing central bearing is
sliding on the flywheel bolting unit. Hold the cover in place and bolt it with the 5 allen cap screw. With a
5mm, torque the cover housing to 90 in-lb.
Make sure the main gear is still spinning freely clockwise.
Pour 300ml of ATF type F oil inside the starter housing.
Place the two small gears back, starting by the upper one. The second one will require meshing top and
bottom gear at the same time. If gear doesn’t want to mesh in, rotate the gear one tooth at a time till
meshing is found.
