Help! Bike bogs if more than half throttle
My 05 vn2000a2 bogs down in all gears if I accelerate hard... I can accelerate slow but tops out at about 70 in 5th. I have powershots, pc3, secondary butterflies removed, and resistor mod. I've replaced the fuel pump/filter, air filter, spark plugs. I have also tried unplugging the pc3 and that didn't make a difference. Engine bogs and dies in park if I roll the throttle hard as well (I can roll it slow and it will rev as high as I want). It's been running great until Thursday morning last week when this started.
