Quality product from a quality Merchant shipping at the right price what else could you want.. Well maybe a five foot six blond or brunette to go on the back of my bike. I'm running a big mm with the power jet on a 92 xr250r street legal so wheelies are a must but the key is .. This one has the adjustable power jet. So basically has a needle in a jet that you can adjust on the Fly. And that's a huge difference from the previous ones I've had. . But after you get this dialed into your machine meaning the main and pilot Jets as well as the needle that goes into the bleed tube. Once you get the clip set right on that and you have your pilot off idle transferring onto the main smoothly while pulling heavily with power. A little extra giddy up that this power jet gives you is phenomenal free extra horses for fifty bucks. All I need to do now is smoothly but abruptly roll onto the throttle and the wheel comes up smooth and predictable. thank you MAIKELONG Store sincerely MoreHPower
