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

Not impressed at all with the magneto which is exactly the same size as the standard and you can't tell the difference from the CD. I weighed the same as the standard they sell I believe. I think they sell you standard parts and call them high performance parts. No difference in engine power between stock and high power engine when they sold it to me.

My engine ran about half a block and then stalled. Note that this happened after the bike crashed twice. After doing some research and fixing most other fuel and carb issues without actually diagnosing with a multimeter, I took a chance and purchased this kit. I just replaced the CDI and coil and that fixed my problem. The bike runs noticeably smoother. I didn't need a magneto or a spark plug, but it's good to have them just in case.

Can't believe I bought again from this lying seller Shame on me. Another one that advertised high performance parts and supplied as standard. I cannot and will never order ignition parts on eBay. Too many sellers offering a standard product advertise high performance. Top performance is not just an expression of good health. It means something serious. This means that a magneto with a larger coil will deliver a higher voltage. cdi means it will fire early. Something my 100cc engine won't start…

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

It is the same as the original, no more performance but it works. My original CDI and magneto stopped working like new on 60 mile bikes so I was very disappointed and ordered this as a last resort because it will now be delivered next day my bike runs like a champ before the bike needs some time to start now it jumps right in without hesitation very happy with the price and fast shipping although it's not a high performance part which doesn't matter to me i just wanted my bike to work because i
