2-stroke thats 4-stroking? - Bobs 4 Cycle Karting A two stroke is 4 stroking when it fires every 4 strokes or every other rotation so, yes it is actually 4 stroking What happens is it's too rich to fire after two strokes but after two more strokes it builds up compression and fires with more torque

GX340 Questions - Bobs 4 Cycle Karting Is there a crank readily available to get the added stroke?
