He's really just testing you to see how much jetski sh_t he can get away with. The final exam was getting you to pose on the jetski. You passed with flying colors.:arms: :arms:

Example
Kaw 750 motor
80mm piston = 8cm
74mm stroke = 7.4cm
displacement= (pi)(r2)(stroke)(2 of cylinders)
=(3.14)(4cm *4cm)(7.4cm)(2)
=(3.14)(16)(7.4)(2)
=(50.24)(7.4)(2)
=(371.776)(2)
=743cms squared or 743cc

Area of a circle = (pi)(r2)
Times this by the height of the cylinder and you get the displacement for one cylinder.
Times this by the number of cylinders and you have the displacement for the motor.

The manifold will bolt onto the 650 block but the 3 bolts on top where the head pipe bolts go is rotated and is not the same as a stock 650 manifold.

Try cleaning and oiling the bendix. They some times rust up and then do not kick out to engage the flywheel.
Also centrifical force when the starter spins the bendix is what causes it to kick out and then the spring in the flywheel cover pushes it back into place.
