Is this a bad coil/starter??

When I go to start up my bike it gives this "zzzzzzzzzzzzzzzzzzzz" consistant noise. Before when I would start it it would at least sputter and clank trying to turn over, but now its just a consistant zzzzzzzzzzzzzzzzzzzzzz buzzing noise it kinda sounds like... the engine sounds like its spinning something, but NOTHING else... I jump start the bike off my cars battery

I have my bike as basic as it can be, the fuel line is fine, the carburetor is brand new so it has to be fine, and I have a brand new spark plug for it. My old spark plug makes the same noise now so its not the plug.

Its either the ENGINE, or (what im PRAYING on) something electrical when starting it...

I uploaded some pics, the fuse is blown in the one, would that for sure be a problem when trying to start it? Also I took a picture of this guys poor electrical work (got it from a previous owner for practically free). Do I have a bad starter it sounds like, or coil or solenoid/whatever its called...

I also am not 100% sure this is an X19 bike so I uploaded a pic as well if anybody can verify it...

Any advice please help me out I took this thing to numerous repair shops nobody will look at it I'm 100% on my own and everybodys doubting me!! lmao

Sounds like your CDI. Its a retangled black box about 1" wide and almost 2" long and the underside is green most times. Here is your CDI.http://www.pocketbikeplanet.com/attachment.php?attachmentid=50435&d=1339090964 Take a good look and see if it looks swollen or looks like it got hot may have some burnt marks on it. You may also want to check for spark pull the plug wire and put a plug in it and lay it againt the frame or cylinder. If the spark is blue the coil is good if its orange the coil is bad and from the looks of it the plug wire at the coil may have broke connection where it goings in to the coil. In which case unscrew the wire and cut about 1/2" off of it and screw it back into the coil try again.

I say the bike is a x12 possibly and the buzzing sound is prob from the starter or starter solenoid pull the spark plug out and make sure the motor is actually turning over first of all

Pull off the stator cover and see if the chain is good and the freewheel sprocket is good thats mounted on the crank behind the flywheel....Good Luck....

It could even be as simple as a bad ground or loose connection.

Well did you check anything else did you see if the motor is actually turning over maybe its the relay maybe its the starter maybe its the starter drive?? These bikes are pos new you need to make them good bikes it takes work and knowledge we will help you with the knowledge but did you check the things we asked you to???

I've done as much as I can, Im never really done this stuff before so im not too smart with it. I really just dont want to invest any more money into this thing though because I dont know if the actual engines fuked up which would make me scrap this thing

The CDI's are cheap and its a easy replacement and they are known to go bad. Check ebay And Im sure thats all it is so take a good look at it for what I told you to look for alright?

Ya don't give up these things are a blast maybe you can take a video and post to YouTube so we can get a better idea of the problem it could be anything if I had it here or saw it I could tell you in a couple of min what the problem is
We are here to help with these problems to the best of our ability but I don't get much from a zzzzzzzzzzzzzz sound that could be the starter
Or the solenoid or the relay or the starter drive we can eliminate that by knowing if the motor is actually cranking over when you crank it or kick it is there and air coming out of the exhaust or can you take out the spark plug and put a finger over the hole and see if is sucks on your finger the pushes it away maybe
I just want to make sure that is working if so than it won't be much to fix

Yes, you just have to work on these things 1 step @ a time - well that goes for any machine. I did have a similar problem though on 1 70cc quad. It was a buzzing starter solenoid relay. It wasn't getting enough power to it & not making the electromagnet inside pull the plunger in fully I believe. Just needed a newer battery
