That works pretty good.
or you can do it the old fashioned way.... bore X bore X stroke x .7854
example:
74.00mm piston 57.3mm stroke (250X)
you move the decimal left one number.
7.4 X 7.4 X 5.73 X .7854 = 246.4387 CCs

Welcome to the forums.... CHeck for anything that may have came unplugged. or a blown fuse. a coild could quit without warning but generally they will work when cold and when they get hot they start to fade away.
