I have a trail port and FMF original Gold series, WOW!! First ride after I got it back, breaking it in you could just tell it wanted to goooooo. After breaking it in, it broke my arms in. Pulled like a beast!!! have a +2 swinger and ride trails and it still jumps, it's more like point and shoot. Torque is great on a shee, and the 450's I ride with can't touch me. Be sure to get some bigger carbs, shee'll be thirsty!!!!! 33's at least, mine still has PLENTY of torque with 33's.
