probably the best alternative is just take the high energy sucking headlights out and install LED lights....
I remember running a bike without the battery decades ago it ran fine
however I stayed too long in town and on the way home I turned on the headlight and it promptly Killed everything electrical... turned the headlight back off and it took off like normal..... that night I put the old battery back in there even though it only produced 8 vdc ...but because of that battery asorbing the altenator pulses I could use my headlight again....it took almost 3 months before I could get a battery from K-mart the cheapest one I could find !
.... I don't know how or why the selenium rectifier lasted through that... I expected it to burn out and leave me stranded along the road. but it never did.
at the time I was thinking all I really needed was a beefy capacitor to replace the battery with ! LOL..... but I didn't have one. I found one the same day I came home with the new battery and almost put it on the bike ...it was a start capacitor for a 2hp electric motor.... I have no idea if that would have worked or burn out the alternator and everything else ...so I just put in the new battery and called it good !!!
now days with the newer Regulators that cost a fortune, you have to re wire alot of stuff to go battery-less.... which in my younger years, was very desirable.. it's nice to not have to worry about the battery being charged !
but with no kick starter on these new bikes you need a battery and good charging system anyway... LOL
.... I snagged a wiring diagram for the 750 Triumph that showed how to go battery-less.... but the New pointless ignition needs 10vdc to fire the sparkplugs.... so I ain't going to do that ! (it's hard enough to Kick that monster through to get it started and right now it starts 1st kick...so I am not messing with it ! HAHAHAHAHA
