I've removed battery from my 91TW and replaced it with a battery lesser (capacitor) and everything works well when started. Obviously there will no longer be an electric start but once kick started it should all work well. You won't have any lights if the bike isn't running. Are you putting led indicator etc? If so you will need a load resistor or they may just stay on or flash too quickly. Not sure about the exhaust, may be just a bit too loud. I used a supertrapp exhaust on mine and it's plenty loud enough
Good luck on the built
