Hi!
The start button never worked, so I always used kick start, but yesterday thanks to the cheap aluminum case, the kick start broke off. Since there's nothing I can do about the kick start, I tried to figure out whats wrong with the start button. I can hear the click when I press it.

Broken kick start:


Spark Plug:


So I took out the spark plug, it was dirty, I took a sand paper to remove all the crap, but still the spark plug doesn't spark when I press the button. So I went to two auto part stores, nether one of them had my spark plugs.

So here I am: Kick start broken, start button doesn't work, the 'running with the bike' startup doesn't work ether. So my question is this, is there any other way how to start up the motor? I even wrapped around string around the motor's gear and then pulled the string out, but no success. Any suggestions?

EDIT: OK, I just bought a new spark plug, plugged it into the wire, but I don't see any sparks when I hit the button, so I guess there's something wrong with the electronics too..

Hi, welcome to the forum. Now that that's out of the way.

1)What kind of bike is it? (Year/Make/Model)

2)What size is the motor? (like 750cc or 45ci)

Thanks!
I bought it used, there ware no stickers or anything about the model, but the brand is SunL. I heard they have a really bad reputation. Even finding a correct spark plug is a problem. I feel like I just waisted bunch of money.

As far as I know it's 2005. The motor is 4 stroke 50cc.

Well... that Google search was unpleasant. I don't know what to tell you.

I got an idea, but I have no idea if it will work and I won't screw something up. If I would take a 9v battery, fix wires to it and at the other end put them together, that would create a spark, and just stick the wires in where the spark plug was, to try to spark up the motor. Would that work?

Your joking right? unless you want to start a fire

Creating a spark is the least of your problems. You need to replace that broken case, or repair it, so you don't splash oil all over kingdom come.

The button you spoke about, was it for an electric starter? If so that button should make the starter motor start turning, which makes the bikes motor turn over, which make all that other stuff start working, like the spark.

Thats one of the problems, when I push the button I can hear the clicking sound, but I guess the electricity gets lost somewhere along the way, so it doesn't even reach the spark plug.

Thats why I was thinking to 'imitate' the spark or find another way how to start the motor since both normal ways [kick start/button] do not work.

sounds like a dead battery to me. That clicking sound you hear is the starter solenoid, but if the battery doesn't have enough juice your starter won't turn.

Take a voltmeter to your battery and see what kind of voltage reading you get, and also see how much fluid (electrolyte) is in your battery - if the cells are low on fluid, you'll need to add distilled water to them to bring them up to the proper levels, then put the battery on a proper charger to get it up to a full charge.

The voltage for battery is 12,5v, but there's no voltage coming out of solenoid. I'm not sure if the solenoid is busted or not, but I thought to take the adapter, attach it to the red and black wires, and plug it in for a second, that would pass some electricity to the spark plug and to the other thing, but I don't know how much voltage and if it's a good idea. Any suggestions?
