_my girl runs 40mph easy with a bullet and 54jet. with 26th 22 rear sprockets. or maybe your way too rich. i found these things dont four stroke easy with sport pipes._
What magic are you using to make it do that, and where can I get some? I have a 14mm carb/intake (14mm ish) that is, admittedly, super janky, but still.... plus a Bullet and a 28t front sprocket, plus I opened up the intake port to match the 14, and did a wee bit of widening ports, and I think I'm going FAST if it decides to go 35. And I've even got the SP, which is the "30" mph version. Apparently I'm still doing something wrong though, because you're not the first person I've heard say that theirs goes significantly faster.
