Honda atc 110 left side case swap.

[jayjones2110]

Can someone tell me for sure if you can swap a left side engine case from a honda atc 90 to a honda atc 110? I think they are the same engine just different bore and stroke. I would like to know before I have both engines torn apart. Any help would be great. Also do you know if the heads are interchangeable?

If its a points and not a CDI motor on the 110 the left case will swap out to the atc90 motor . Heads are interchangable I believe from 1973-85 atc 90-110 but the cams are different on the 81-85 model 110 from the atc90s.
