Hey Guys,
Brand new to the forum.
On the Battery delete issue. I never run batteries. Small capacitor (commonly avail. on eBay for Triu/BSA's).
Wire it just as you would the battery. ONLY real issue is you may get some flickering of the headlight at idle and you obviously wont have any lights until the bike is running, thus producing alternator output.
You must wire your ignition for Start Only (no lights, just brake light switch so you can run lights off, but still have your brake light)
Then turn your lights on using the Acc. or 2nd position on your ignition switch.
I usually run an On/Off/On toggle in my headlight as well.
I do NOT run turn signals, but see no reason why you couldn't.
Also switch out any separate voltage regulators/rectifiers with a single modern solid-state unit.
Bam! No battery.
