Small size battery
 

I'm putting in a&nbsp\\;tiny size battery (4L-BS) into my '77 kickstart only bike.&nbsp\\; I'm thinking that it will be OK, because the regulator is going regulate and not fry the battery.&nbsp\\; Any experience on this?
The batter is 4 amps, 12 volts, and drops into the horseshoe oil tank nicely.&nbsp\\; Running an old knuckle oil tank, so it's limited space.

I put anOdyssey PC 310 Bat on my 52 pan/shovel 5 years ago The size is 5.43 L 3.39 W 3.98 H I put it in side ways Gel type bat&nbsp\\; so you can do this Kind of expensive but those jap /china bats don't have much lead !

As long as your charging system is fine and not running a ton of lights it should be ok. Kicker bike would be easier on battery.Those old horseshoe tanks can cook a battery due to its style.A smaller size battery and the ability to allow cooler air upon it would only help.
