Banshee discplacement formula

[blaster2006]

heya, i noticed there was a sticky for a chart that shows a chart of bore size and stroke etc to find your displacement, i found t rather confusing, and i thought i might just put this formula up, although im sure most of you already know it.

 

BORE (in cm) X BORE (in cm) X STROKE (in cm) X .7854 = Cylinder cc's

 

For example, for the banshee, its bore size is 64mm, and its stroke is 54mm, which is 6.4cm bore and 5.4 cm stroke (just divide by 10, move the decimal point one time to the left).

 

so its 6.4 X 6.4 X 5.4 X.7854 = 173.71

 

since its a V twin you multiply that number by 2 so its 173 X 2 = 347.4 cc

Here's a peice of cake calculation......

 

Bore x Bore x Stroke x 2 x 0.0007854

 

64 x 64 x 54 x 2 x 0.0007854 = 347.4358272 cc's

68 x 68 x 58 x 2 x 0.0007854 = 421.2759936 cc's
