If Royal Enfield UCE motorcycle does not start in neutral but does start when clutch lever is pulled in, the neutral switch (NS) is not grounding the circuit properly. Neutral switch has a spring loaded ball. Clean the NS and its connector thoroughly.
It is not really a switch – as it cannot turn on or off neutral light on its own. A protruding nipple on gear cam plate touches NS in neutral that grounds the circuit. It is essentially a ground wire with a spring loaded ball for contact.
Thanks to Matt for picture of cam plate in the crankcase.
