An ignition event occurs at the end of every other revolution. An intake stroke is half the revolution. Therefore, at 6000 rpm, half your strokes are on the power and exhaust, the other half are on intake and compression. Half of intake and compression is intake. So you have 3000 ignition events but only 1500 intake strokes.
