Somebody please answer this one, please! If a 2 stroke MOTOR costs $1500 in base manufacturing costs to build (just throwing out a guesstimate) than you would think the Yam 4 stroke motor would cost $3200.
More cylinders to cast bore and hone, twice as many pistons, a much more complicated crank shaft that needs to be machined more precisely.
Plus
Instead of just basically a hunk of aluminum for a cylinder head, you have dual cams, 5 valves per cylinder all the drive sprockets, cam followers, springs
Plus
you have a lubrication system, and not just any, it is dry sump like a race car or a Porsche 911
Plus
you have magnesium covers and a titanium header and front end brackets to help offset the additional weight.
Plus
you have a crank speed reduction unit (gear reduction)
plus
you have what, 3 times as many parts for steering, because the steering columns jog around the engine and then back to center
HOW IN BLOODY hell are they selling these 4 strokes at near 2 stroke prices??????????????????
The average guy does not realize how freaking incredible this is!!!!!!!!!!
