52? Thats it? 150cc powermax

[scootypuffxl]

so since I dewinterized my scoot, it has lost power. Before put up in storage was running 58 to 62 mph on flat. First real ride I've taken since cleaning carb and I can't get over 52 mph... wtf, did I clean my carb wrong? Any input is appreciated. Oh ita a 2020 powermax 150, with a9 cam, exhaust, and up jetted carb with intake and cone filter...

Maybe the weather conditions have changed enough that the carb is out of tune now. Have you tried any other main jets? Tire pressures good?

exhaust could have some build up that solidified while sitting? That could decrease the flow. just a thought but may be not helpful to look into.
