I have had them on various mx bikes with no issues. These kits are universal applications. Some models may require you to drill larger mounting holes, sand a section of the mounting plate with a file to open up a slot or sand mounts down. Some bikes do required the use of extra gaskets under the ignition cover to make enough clearance for the stator. The magnetos do not have a keyway. You have to set the timing with a dial indicator and then torque down the crank nut. They stay in place once tightened. Includes free UPS Ground shipping in the USA.
