We have here in Czech Republic many of Vietnamese flea markets, where you can find small "flashlight" paralysers, that contains - one 9 Volt battery, 9 V -> X00 V converter, HUGE capacitor, trigger circuit and finally powerfull high voltage impulse transformer.
I think that these modifications must be made to make it into ignition: Make the trigger circuit switch-controlled. Mount more "power-proof" transistor with heatsink. Power it with 6 volt lead-acid battery charged from dynamo. One lead from transformer ground, the other connect with HV wire to spark plug.
And BANG! You have cheap ignition.
Warning!!!: The capacitor is ALWAYS charged with high voltage! Short it with screwdriver and measure the voltage before doing anything!
Are you having some Vietnamese markets in your country?
