I know alot of people wants this info. So here's a simple formula to figure it out. to figure out the cc's of a motor get out a calculater and try this;
bore x bore x stroke x .0007854 = cc (after you round the .#)
for example I'll do a 300EX's...............
stock 300 EX's bore is 74mm x 65.5mm stroke
74 x 74 x 65.5 x .0007854 = 281.7----(282cc)
And remember for every .020" is a .5 mm
So if you take a stock 300 (74mm) and bore it .080" over it will make the bore at 76mm.
(For a Banshee you just take the final total x 2)
Hope this helps!;)
