Vkinman CDI Ignition Coil + Magneto Coil + Spark Plug for 49cc-80cc 2-Stroke Engine Motorized Bicycle Bike

So I works, when I opened the package I had this product along with a new magnet for the magneto, and they were stuck together, later found out that the coil was open but I believe that it was because of the magnet and the coil colliding during shipping, fixed it and it works very well, but i don’t really know the cause of the open coil

Gosh when I got into my old magneto I could smell it like it smells like a burnt piece of electronic equipment always does this item arrived timely installed rather quickly I waited at least a month or so before I walked over to this project and flip the things out I knew the magneto I had was burnt thanks for a timely delivery of an extremely good product no magneto no spark this magneto works thank you

used the cdi to replace the one that somehow broke on my motorized bike. it has worked well so far. feels like decent quality. no idea about the magnet thing since i didn't have to replace mine, but it looks like it would work fine. same with the spark plug. if you are trying to fix a no spark issue you might as well just buy something like this with all three parts in case you need them.

If you do buy this product I suggest to take off the spark plug cap and cut off the head of the lead wire and buy a ngk spark plug cap and screw that one on instead (could be found at advance auto parts and not autozone)The CDI feels heavier than the stock cdi and looks better put together but of course that doesn’t mean performanceThe magneto for the kit does not include the 3rd 6/12v white wire so that’s a plus but it seems with all the magneto’s I have gone through they all fit the stock magnet but the groves inside the magneto arms are a little bit shorter then that of stock whether or not this helps I am not sure of but both sides of the magneto arms look equal distance for the magnet which is want you anywaysThe spark plug is not as long as the regular ngk spark plugs (Standard recommendation for bike) and heat index is a 7I usually run a B6HS and I’m waiting on a new carburetor (the red and blue HP carbs sold on amazon here) because it’s better to start with a new spark plug when and testing them and adjustingI will let you know how they hold up after a week of use because I rely on my bike for daily travel

The second most important upgrade as far as I am concerned (number 1 being the chain tensioner, because the stock one is a dangerous piece of garbage). Helps the bike fire up on the first attempt every time now. Plus the stock spark plug wire that came with my kit was defective.

#1) Sold me a Magneto and a CDI. Yes. Sold me a high performance magneto and CDI I Think NOT! This is Standard Magento only. observe the hight of the copper windings. (picture I) Does not meet The hight of the plastic ends. Standard! High performance the winding meets the hight of the plastic. Super Magneto Exceeds the hight. The cause is more copper which means more $. I paid more $ and got less. #2) 333ohms ? That is not new! 350 ohms is new 325is a Dead Magneto. 333 ohms means it will be dead in Just a couple months. #3) CDI Mount bolts missing nuts. Do you now see why I suspect it is a standard CDI with a red plug wire?on second thought...the magneto is not a standard but a below standard.
