    Do a site search here for HT sizing guide, or a similar term. There is just such a line drawing readily available. Or, easier yet, lay the engine on a piece of cardboard and draw an oval around it that is close but not right up against it, then hold that piece of cardboard up to the frame opening of a bike you are interested in, to see if it will fit.

    Welcome to MBc. And, once again, excellent common sense advice from SS.
