How about this one: What you have to worry about is the holes to mount it. Just use the plug on the 6 pole one. Reach in there with a small screwdriver and open the tab and pull the wire with it's connector and just swap plugs. Same wires 5 on both, 3 go to the R/R the two loose ones the blue goes to the Trigger slot on the CDI and the other is the power wire goes on the bottom of the 2 plug on the CDI.

**New info**
Alright so here's the latest.

I purchased a stator
link
It was one of the only I could find with everything correct except for the plug tip which I swapped with my old one.

Installed it and it started up but ran really rough.
I took a look at my plug and it was sooty.
I still had an old plug under the seat from when I swapped with the current one, it wasn't really bad but I just wanted the NGK, so I put that in there.
Still running rough.
I know it was sitting for several months, but like I told you guys before, I broke down and cleaned the carb so I pretty much ruled that out.

Test Drive
**Side note** I also ordered and put on: A new belt, new rollers 5g and new variator guides.

It rolled rough but ok at about 2-4MPH giving it slight throttle, but when I tried to speed up, it started reving(still roughly) like my belt was slipping.
But when putting on the new belt, when pulling the clutch plate back to drop the belt in, it kinda felt like a little sticky/rusty(my guess is from sitting a few months?) and I was concerned a little that it wouldn't smoothly open and close or maybe the plate was a little crooked and would wobble while spinning.
I attempted to take the CVT cover off while the bike was running to see if maybe it was wobbling or running smooth, well the bike didn't start up anymore.(it started a few times prior to my test drive after stator installation)

I got the multi-meter out and went through the full test from the video again.
Everything was ok accept for a few things, so ill just post the oddities.

New Multi-meter test
Black and Yellow wire on the CDI that goes to the coil showed .03 which is too low.
Crank test:
Black and Red wire on the CDI while cranking reads 43.v
Red and White wire on the CDI while cranking reads .071 (too low)
Resistance test:
From the bottom of the spark plug to the top terminals of the ignition coil with the multi-meter set to 20k reads 7.79.


**On a side note**
During the crank test the bike started up once and ran (I had to keep some throttle for it not to die) but while trying to remove the CVT cover, It cut off because I couldn't do both, keep it idled and remove the bolts.


Please help, I really need to get running again.


I'm about two seconds from getting this and being done with it.

I already wanted to upgrade anyway but my question is,
will this fit my 50cc or do I have to get the 80cc kit?(my research says it will, but I heard a few things about going all the way up to 100cc...)
It will help solve my spark problem if it's my coil at the same time as well.
Also im getting a performance spark plug as well, any suggestions on the best one?

Please help thanks.
