Razor MX350 version 8 control modification.

Razor has discontinued the controller module and throttle assembly for the version 8 MX350, 101520-08. The control mod W15128040164 is hard to find. Need wiring diagram and a how to for using the SPD-YK31C24 and the THR-84 in order to swap out the bad controller for a different one.

Thanks!


Important Update: We now have a plug-and-play controller available for the Razor MX350 version 8 so the SPD-YK31C24 no longer has to be converted to be a replacement controller.


The new plug-and-play controller for Razor MX350 version 8 is our item # SPD-CT201C63:  Add to Cart







For historical purposes we are leaving the parts list and wiring diagram below for custom installing the SPD-YK31C24 controller, however, we highly recommend using the SPD-CT201C63 controller listed above as it is plug-and-play, and requires no modifications or custom installation to install.



Here is the list of the parts required to convert all versions of the Razor Dirt Rocket MX350 electric dirt bike to use the SPD-YK31C24 speed controller and THR-84 throttle:


1 Qty. SPD-YK31C24 (new item # SPD-24500B) Speed Controller Add to Cart

1 Qty. THR-84 Throttle Add to Cart

1 Qty. CNX-50 Connector Add to Cart

4 Qty. CNX-51 Connector Add to Cart

1 Qty. CNX-52 Connector Add to Cart


Installation requires one CNX-50, four CNX-51, and one CNX-52 connector sets.


Here is a wiring diagram that shows how to wire these parts to the Razor Dirt Rocket MX350 dirt bike:
