nunquam scienter utilis
nowt about the bike, selling a fantasy that 99.999% GS's will never experience, getting out the garage on a rainy day let alone going off road.Nice images but not really informative. Any ideas why the inlet is now above, and the exhaust now below, the cylinder head?
Fixed it for you Dave
Putting the inlets above the heads gets the throttle bodies etc out of the way of the riders' shins. Also, I understand that fitting 2 camshafts/4 valves in the head was a problem on the boxers, and meant that each cam drove one inlet and one exhaust valve... the camshafts ran horizontally. Putting the inlet tractss above the head, and the exhaust tractss below, means that, now, the upper camshaft drives only inlet valves, and the lower only exhausts, which, presumably, makes manufacture easier. They couldn't do this with air-cooled heads - had to keep the exhaust port right out in the airstream - but with water cooling the port can be well-cooled regardless of its orientation.Any ideas why the inlet is now above, and the exhaust now below, the cylinder head?
