BBoy69 Posted July 26, 2017 Report Posted July 26, 2017 Ok I may just be being a dip shit here lol but could somebody tell me what's the difference between a dune port and a drag port ? Quote
spurdy Posted July 26, 2017 Report Posted July 26, 2017 The porting on a two stroke is like a cam on a 4 stroke. It controls your intake and exhaust durations. Different port timings will determine when the engine makes peak power. A dune port will cause the power to come on earlier and more evenly than a drag port that causes the power to come on at a higher rpm range and more aggressively.

spurdy Posted July 26, 2017 Report Posted July 26, 2017 On a dune/trail port, the power would come on more evenly as you roll into the throttle and RPMs increase. If you did that on a drag port it would act lazy until it finally reach a high enough rpm range and then it would make power violently. Sent from my iPhone using Tapatalk 1 Quote
