It has a pwk28 carb, bills pipe, v force reeds, 42/130 jetting, power valve is functioning. If you start in first and go WOT throttle it’s great runs fine, powers good what not. But if you ar let’s say in 3rd and get into the power band and have to let out and coast and get back in(in the same gear) it does this bog. If you shift or pull the clutch in it comes back. https://youtube.com/shorts/eDrD9622dn8?si=unnVQkGrXKuYDZQS it normally does it much worse than in this video(of course I go take a video and it semi works) but it really just goes buhhhhhhhhh and like I said it will come back if you shift or pull the clutch in.
