johnnyrod Posted June 10, 2010 Author Report Share Posted June 10, 2010 I was thinking more about this... these engines: inline 4 ("normal" crank) parallel twin single cylinder opposed twin all should have the same characterstic in that all the pistons are either at BDC or TDC at the same time, but the V-twin is the only one that doesn't (ignoring 6-cyl etc.) in that one piston is at TDC or BDC while the other is part-way through the stroke. So is the same true when comparing e.g a BMW to an SV? Also what was the crank configuration used on the "big bang" 500cc 2-strokes, and the "normal" ones come to think of it?
