As suspected, the starter motor fault was due to the 3 bolts that secure the sprag clutch were loose. I tightened them and now the starter fault is cured
I got the bike running, but the oil light remains illuminated when the bike is running. Testing the circuit, appears that the wiring circuit is grounded somewhere
I tested the switch, its fine
Any leads/clues where the wire could be trapped, or damaged ?. I see on the wiring diagram there is a junction box, where is this located ?
