I ussed to have a 92 GSXR that had a moped battery mounted to the contershaft cover. I did live in Hawaii though. And that bike started instantly.I’m trying to decide between the antigravity 4cell and the 8cell. I have a 73 CB450 and I want to use the electric start for it. Will the 4 be enough? I’d prefer the 4 over the 8 due to the size.
I suspect if your bike starts and runs well you could get by with one of these but why not get an 8 cell. I ran 2 of the 4 cells on a bike before due to space constraints. If you do this just be sure you understand the difference between parallel and series battery wiring.
