This is really just a personal interest post, and if any one has any input, or maybe even has an answer, do not hesitate.
So, riddle me this... Why are the intake and exhaust manifolds orientated the way they are on motorcycles. To me, it would make sense to have the air enter the engine from the front, because it comes from the front. And it would also make sense to have the exhaust leave the engine from the rear, since it goes to the rear of the bike. As it stands, each of the intake/exhaust gasses wraps around the engine before entering it. My only real guess as to why this is, is because there is simpy no room for an airbox and carbs/injector bodies in front of the engine. But to me, this would seem like something worth looking into, especially with all the advancements modern motorcycles have. Straightening the intake and exhaust paths would result in less turbulance in the intake, and would even save power on the exhaust. I think moving the engine back could help create enough space in the front end, and as far as street bikes are concerned, the advantage gained by having the CG farther foreward isn't as important as in race bikes. Well, these are my thoughts for the day.
