How to Calculate Deck Height into CC's

the inch system

Formula - Bore (in.) X Bore (in.m) X Stroke (in.) X 12.87 = Deck in CC
Example - 90.5mm = 3.563" X 3.563" X .060" X 12.87 = 9.80cc
1mm = .03937

or the mm system

Formula - Bore (mm) X Bore (mm) X Deck Height (in.) X .01996 = Deck in CC
Example - 90.5 X 90.5 X .060" X .01996 = 9.80cc

Deck Piston - Deck Height in CC's

How to Calculate Engine CC's

Formula - Bore (mm) X Bore (mm) X Stroke (mm) X 3.1416" = Engine cc
Example - 90.5 X 90.5 X 69mm X 3.1416 = 1775cc (to get the Volume of 1 cylinder in CC divide by 4)
Example - 1775 ÷ 4 = 443.75

Bore Stroke - Engine Displacement in CC's
64 69 74 76 78 82 84
77 1192* 1286* 1378 1415 1453 1527  
83 1385 1493* 1601 1644 1688 1774 1818
85.5 1496 1584* 1699 1745 1791 1882 1929
87 1521 1640 1759 1806 1855 1949 1997

94 1776 1915 2052 2109 2165 2275 2332
*1192 = 1200cc Engine *1493 = 1500cc Engine
*1286 = 1300cc Engine *1584 = 1600cc Engine
