Review on Enhanced 2-Stroke Engine Performance Kit: CDI Ignition Coil, Magneto Coil, Spark Plug for 49cc-80cc Motorized Bicycle Bike by Carl Estell

If you buy this product, I suggest removing the spark plug cap and cutting off the head of the connecting wire, instead buying the ngk spark plug cap and screwing it on (can fit into pre auto parts, not in the Autozone ) The CDI seems to be heavier than the standard CDI and looks better assembled, but of course that doesn't mean performance. The magneto for the kit doesn't include the 3rd white 6/12v wire so that's a plus, but it seems that all the magnets I've gone through all fit the original magnet, but the grooves in the magneto arms are a bit shorter than the stock ones, I'm not sure if that would help, but both sides of the Magnet arms seem to be the same spacing for the magnet you need anyway. The spark plug is not as long as normal ngk spark plugs (standard motorcycle recommendation) and the heat index is 7. I usually use a B6HS and am waiting for a new carburetor (red and blue HP c plugs are sold here on Amazon) because it so it's better to start with new spark plugs by testing and adjusting them. I'll let you know how they hold up after a week of use as I rely on my bike for my daily commute.
