My friend rides a 2014 BO CVO, he is experiencing some excelleration isues between 2500 and 3000 rpm. It feels like the engine is getting bogged down and at 3000 rpm it does start to pull like it should. It was like that since new and when speaking to HD they just looked at him if has 3 heads and say it is normal. He recently installed a V&H 2 into 1 big radius and a FP3 but problem still the same. Anybody with some advice would be appreciated.
