Does a moped put out enough unburned fuel to power one of those things? I'm also assuming you'd need an auxillary battery to power those coils.
If anyone does this... please let me know. I love this idea.
What would happen if you poured a bunch of oil into the exhaust by tipping the moped forward a little, and making sure a lot of oil drooled down to the hot spots near the manifold...--- as soon as you built up temp, would it begin to smoke like crazy?
