well almost none of the 110 /125 parts will interchange.
diffrent cases,flywheel,cyl,head,pullstarter (right side case is the same) and the 125 has pull start and electric....the 110 is just pull...
BUT they motors will bolt in one anothers frame....same mounting pattern

Thanks guys. I'm new to the forum but have been around ATC's my whole life. I have an 84 110 that has been in my family for 23 years and I would like to give it some TLC. I noticed that the 110 and 125 look almost identical so I was wondering if they are the same motor with a different bore or completely different. So thanks again for clearing it up.
