Does size really matter?!
I have an engine that says it should work on a 26-27 " bike. I have my eyes on a 29 in her at Wally world. What is the size and what wouldni need to do to have my current engine on the bike I want from walmart? If it's a matter of a new longer chain that is fine. Also if it makes a difference I have a frame adaptor kit for the engine.
