ok. i ride my shee in the woods/trails a lot.. i do love to jump on a backyard dragstrip and run the hell out of it.. i am wanting to port a set of stock cyl's but not sure what kind of port job would be best for me.. i really love a snappy motor that still pulls hard on top.. i have cubs right now and i need more mid and lowend power.. i like the powerband to hit when i snap the throttle open instantly.. any help?? i have t5's vforce, head, 33 pwks. i heard that jim at passion racing is the best?
