cost of a rebuild on a 2 stroke $200 cost on a 4 stroke $2,000 hmmmm. a 2 stroke revs faster giving you that shot when needed. the overall package is much lighter. a 2 stroke is easier and faster on a hot restart. carb tuning on a 2 stroke is a snap compared to the 4 which can take days to get perfect. i mean i can go on for days. 4 strokes are great but there arent enough advantages yet
