need help with 196? s90

I was wondering if anyone had any thoughts on how to make it a cdi.
thanks

Could try an Ignition system off a Newer CT110 or ATC110,,,,,,bout 99% sure it will bolt right in.

[82'185s]

i have an 82 110 and it has more of a 185 style setup on it and the s90 has the coils around the magnets and it doesnt really look like there is enough room beacuse of the cam chain tensioner.

ok any thoughts on take the left side case of a atc 90 or a newer style 90 bike

and does anyone know what year they started using cdi

thanks
