Review on Yingshop Ignition 2 Stroke Motorized Bicycle by Youssef Coolidge

So I just got this CDI mailed to my house and I got it today and I'm going to try to fit it, you can't even put the damn spark plug that comes with it and it's very cheap made of super cheap plastic it's not even a rubber case like the others. I'm really pissed right now because I just spent so much money and it doesn't even match the spark plugs I have on this thing. including the one they sent it with, which doesn't make sense to me, why would you ship something without testing it first, which makes absolutely no sense because if they actually tested their products they would know it wasn't fits ., . So after using it for a while I found out that there are some spark plugs that have a screw cap at the very end, it doesn't mean they have something like that so I figured they just gave me a faulty item and i was wrong it actually works great which is great now my bike has never worked better so i changed my rating to five stars because there is absolutely nothing wrong with it and once i understood it but um To be honest I've never seen or heard of a spark plug that has a screw cap on the end.
