The Yamaha G1 Golf cart, equipped with a 215cc engine, has a bore of 70 mm and a stroke of 65 mm. This configuration contributes to the engine's performance in terms of power and torque output. The specific dimensions are integral to the engine's design and efficiency in a golf cart application.
The Bore of a 350 cid engine is 4.00, the stroke is 3.48 inch..
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
That'd be a motor with a 90.5 mm stroke and 69 mm bore.
It refers to the throws of the crankshaft/distance the piston moves. It usually is compared to the bore of the engine. An example a 302 4"bore x 3"stroke is a short stroke motor, by comparison a 5.4L ford v8 3.552" bore x 4.165" stroke.
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....

The bore and stroke.
Bore = the (internal) diameter of the cylnder hole in the engine block. Stroke = the distance the piston travels up (or down) the bore during its' cycle. If you multiply the bore dimension by the stroke dimension you will get the volumetric displacement of that cylinder. thus, Vd = (3.1416/4) (dia.) squared x Stroke
427 = 4.250" x 3.76"
3.48 inches.
