complete loss of power at high speed low rpm

Well like the title says I lose it almost dies Ans will die if I pull in the clutch in anything after 2nd gear. Acts like poogs but its all clean and new and makes no difference. If I go high rpm its fine. Any clues?

Could be clogged pilot(s) in the carb(s). Your description isn't fully consistent with this though.

How does it idle ? Can you run up the throttle and sounds ok? I had a simular issue with mine, try to give it gas and it bougs down. But my bike sat awhile. I used 1/2 can of seafoam in a freash tank of gas and it cleared up.

It idles perfect. Carbs are clean, tank Is clean, gas is new, non ethonol. Runs through the entire rpm band perfect with no load, if I give it hell it runs perfect, but if I try to cruise it bogs down, then I can work the throttle open and closed and get to a lower gear and its five again until I try to cruise again. I just put a new gas cap on today too, and cleaned the system. It doesn't do this everytime. But 8/10 rides it will. Just started this two days ago, carbs were cleaned two weeks ago, and then again today. No change.

Fixed It. Bowl vent tube came out and I didn't notice it. It was catching wind.
