Picked up this jem from my boss. Its been sitting in her barn for who knows how long. I cant find any damn info on the numbers off the frame or motor. Also has no cc marked on it.
Heres the numbers off the frame and motor if it helps.

Thats what i had it narrowed down too but the numbers dont seem too match. The site i got them from might have a typo or something, i dont kno im stumped.

Here we go.
1975 MC1MA.
Engine serial numbers for this model start at MCE 509500.

The only difference between the B and the MA is the tank and stripe color.

I was gonna guess an 80cc or around there. I have a 1973 Honda Trail 70cc nike. I've had it since I was 8 years old. About 20 years. I will never sell it.

WOW!!!! That is one of the first dirt bikes I road years ago as a kid (I know, I'm old). Basically the same exact model as I remember. I can still see the field I rode it in and I can smell the two-stroke smoke that thing would puff... love it.

Anyway, that little bike should be either a 90cc or a 100cc bike. All of them had oil injection and I would guess it to be a 1979 or so...

The motor looks just like my old 73' KE100

 

[BrainFearGone]

well got it running but for some reason now it has a really weak spark. Pissing me off

new plugs and coils? cheap tune up might help, that was the problem when only one cylinder on my bike was firing, 2 dollar fix lol

 

[BrainFearGone]

got a new plug but cant find a new coil for it. It has a coil with molded plug wire into it. Can i just wire up any 6v coil?
