I'm not sure, but I've been told the risk with having a starter button on the handlebars is that I could accidentally engage the starter while the engine is running. But as I will be disconnecting the battery after the engine fires up, this is not a problem. I use to carry a battery on the machine at one time, but found it too difficult to mount and the vibration killed the batteries in a short time. So now I just wheel the battery around separately on a dolly to start the machine with some Anderson cables.
The following is posted for information purposes only!
For applications where the battery is permanently connected, I can only suggest a timed relay to shut the starter motor off after the engine fires, or adding an extra switch to turn the starter on and off. Something like this might do the job perfectly. I can only find these switches for sale in America and they are pricey. Could probably get one for a few bucks on a site like AliExpress, that is if it ever arrives.
The Blue and Black wires on START are not needed and only two wires not three needed for the on/off switch.
There seem to be two different models (NO and NC) for the off/on, but I've been told the wiring can be changed simply by removing a rubber seal at the bottom of the switches.
