So, i have one of those 50cc 2-stroke bicycle motors. It has magneto and that's what gives coil energy to generate spark. Do you guys think there is enough energy to spare some of it on transformer+voltage regulator for simple tasks like LED lights or maybe even something heavier like USB charging? Is magneto energy even consistent enough to not overheat voltage regulator on entire RPM range?

What you want is a second charging coil and a battery. These are common on ride on mowers etc. One problem they have is they deliver power in pulses as the magnet passes so you will need something to smooth this out like a battery.

So, connecting to existing magneto (which generates spark power) is bad idea?
I don't know how large those pulses are, but i'm willing to bet that proper capacitor (and couple of zener diodes, basically simplest AC/DC power supply scheme) would be enough.

No, it won't work. Take the pants off your head and quit being stupid.

Or connect it to a generator? (An old DC motor will generate electricity when turned...

You need a second coil for power, or attach a small generator/motor/alternator.
