What spark plug does this bike need?

[akid420]

First off, hello every one. I belong to a few car forums but this will be my first bike one.
I am very mechanically inclined. I've done just about anything to cars, however I am new to small engines apart from the ones I would tweak when landscaping :hmmm:.
Me and my buddy did landscaping over the summer which led to us buying a truck, once we had the truck we had to get some toys. We picked up two bikes as a package deal.
One is a mini dirt bike. The second is a bigger mini bike but road style. I will try to post some pictures a lil later.

Problem:
I can't get the mini dirt bike to run. This is because it had the wrong spark plug when we bought it. Like a dumb-ass I never checked it before trying to start it. After a few miserable fails I pulled the plug. The gap was inexistent. The electrode and the bridge were touching. So I re-gapped to .3 I believe and stuck it back in. Tried to re-start and nothing, pulled the plug and the bridge had flattened down again. Therefore this is the wrong plug. I have tried searching on the internet, but all I get is a bit of info on the bike, but nothing about what kind of plug.
I have been stuck on this for a few weeks and finally gave up and decided to post here hopping for some insight.

Info:
Found on head: YH404CC
Manufacturer: Wuyi Yuhuangxing Industry and Trade Company
Product: DB
MDI: YHXDB209
Time: 2008
Origin: China

TIA

hi,
is it like the bike in this link ?
if so, it uses an A7TC spark plug usually, gapped to around .6 or .7mm

hey

ya it is. thanks for the super fast response. i will be ordering it tonight, hopefully will fix the problem.
any suggestions on where to buy it? ive noticed no local store have it in stock? websites?

for kicks here is a terrible pic of the second bike. any info would be great, especially since the code on the bike bring up nothing when searching.

again thanks a lot, i would still be stumped.

there's supposed to be a plastic piece that surrounds the engine area.

Hey guys. Little update...

We got the mini dirt bike running after a good amount of trial and error. Finally found the right plug and got it running great!

The link to the plug above was not the right one, but funny enough it was the right one for the bike pictured just above. However this bike has way more wiring and a lot of it has melted. Any one have any ideas what kind of bike it is? i'd be happy to even know if its considered a "pocket ike" or a "mini bike" or just a "street bike"? Excuse my ignorance i am still new to this game.

Thanks for any advice again.

PS the picture of the bike is missing a good amount of plastic that i removed to work on it. their was a piece that wraps around the front/bottom, also a headlight and finally a plastic windshield. Many of the parts also have a "W" on them.
