My knowledge of Lithium batteries on motorcycles is purely from ready.
Regarding the addition of a small battery: Check first if your rectifier/regulator is suitable for Lead or Lithium. For Lead the output voltage will be in the range 14.2 - 14.7Volts which is too high for Lithium Iron Phosphate batteries and could give you minor or extreme trouble depending on your luck. Lithium Iron Phosphate batteries use a regulator that puts out 14.0 +/- 0.2 Volts.
Note: Lithium Iron Phosphate batteries have advantages over the older Lithium Ion type. Lithium batteries should have a Battery Management System (BMA or Bma) to give balanced charging and over/under voltage charge/discharge protection. Lead batteries are still the standard and not to be ignored completely.

that's good information, thanks. i'm leaning toward replacing the capacitor with a small lead battery. i'm tired of capacitors; i don't know enough about them. it'll still be kick start only so i don't need to worry about a huge battery box...

You can test capacitors with an old style analog multimeter. Charge the cap up by touching the wires to a fully charged battery, then set your meter on "volts" and touch the leads to the capacitor wires. The needle jump up to indicate voltage, then drop, as the cap discharges.
