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

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 media could not be loaded. Everything came as was supposed to except for the magneto coil

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.

The media could not be loaded. Magneto doesn’t have an accessory wire

My old CDI and magneto went out from original build. I installed and my engine came back to life with better performance! Will by again if need to!

Made my engine run much better. More power.

As where the sides of the magneto itself are suppose to be precisely parallel it came looking bent out making the precision required in spacing it properly upon installation impossible. Bike still runs but it certainly didn't make anything better. In fact I'm left wondering if that can be the source of other minor issues.
