yeah thanks for that. I'll take it all on board. I do understand electrics a fair bit and are aware of the component issues but to my thinking the starter, alternator, timing hall sensor, spark plugs temp gauge. are all earthed to the engine, which will not change. the engine is earthed to the frame anyway because it's bolted in there. but will be hard wired to make sure. the CDI, solenoid, flasher unit, regulator, fuse box, are all isolated being in plastic/rubber mounts or housings that will not change. the lights, indicators are already wired to the frame and work perfectly.
plus there is already a frame earth point on the thermostat housing. the main difference is I intend to utilise the frame as a main earth point to shorten the tails and delete those long starter wires save one. electrolysis can be an issue I agree but using the right materials should lessen the issue.
I am fairly happy I covered all the bases. but wanted to ask the experts on this peculiar bike. just in case I missed something.
