btw i have a question on ports.. wats the meaning of 3/5port engines.. wats the difference???
any1 pls pls tell me.... thnx thnx
the os engines would be the ones to go for, cause they're easier to tune and have a good reputation for reliability. as for ports , a 3 or 5 port refers to the number of inlet slots in the piston sleeve that feed the fuel mixture into the combution chamber, generally an unmodified 5 port motor will have a little more power than the same type 3 port motor , hope that helps you out
