hey guys, can you guys tell me if the go 3 port sport has alot of low end torque,the two tracks i go practice are small and technical.so i really dont need something with alot of top end.my freind is using a v-spec and never get to use full throttle on the straight,but he clears all the jumps.so i was looking for an inexpensive engine with alot of bottom,how realiable are these compare to the 3 port race.and are the sport having needle issues.i would really aprecciate your advice, thank you. i have a budget thats why iam considering the sport only.and where do you recommend for me to do my purchase.ebay or online store,
