My dilemma is that I am restoring a rare 1975 Daihatsu Hallo (see my thread here: itistheride.boards.net/index.cgi?action=display&board=50ac&thread=288&page=1#4036) and replacement parts (piston and rings) are proving very difficult to find.
With the possibility of not being able to find those parts nor a suitable replacement piston from another engine, does anyone know how easy it is to replace the entire top end (and con-rod if necessary) with, say, parts from another similar engine (in terms of bore/stroke)- Replacing the entire engine is actually harder due to the way this three wheeler is laid out.
What things do I need to take into consideration (Stud placement and diameter, port position, con-rod length...?) and, in the opinion of any wise scooterers, is this a feasible solution?
It's a fairly extreme solution I admit, but I'm not having any luck trying to find a new piston and rings. Trying to find a piston from another engine is also proving hard with the combination of bore, stroke, piston height, wrist pin diameter, ring location, squash area etc etc.
