Even the recommended size batteries barely get the job done, especially if you have mods in the engine/high compression.

Good luck.

It will help if the battery cables from the terminals are changed to a larger size. 6 gauge welding cable with the correct crimped on terminals increases the current going to the starter motor.

Also the cable going from the Positive(+) terminal to the starter solenoid and from there to the starter motor, don't forget the Negative(-) battery trminal to the engine mounting bolt too.

I think the ballpark is at least 15 Amp-hour. More is better.

I don't think you'll get away with something like that Joe, at least not for long. You could give one of these a shot though!

The small lithium cells can start a bike, sure, but sucking that much amperage out of that tiny capacitance that quickly = dead/weak cells, VERY quickly. I used to run RC cars off those cell packs we built and they only lasted about 15 minutes.

If you like building and replacing battery packs frequently - go for it.

The reason that the batteries are large is not just for the amperage capacity, but also to act as a buffer/capacitor for the charging system, to help smooth out the power.

There is probly some fancy light/small race approved batteries I might use, but for a street bike...? I dont know.

Peace.
