OK first off, sorry for not being here in a long time I just made it home from Afghanistan about two weeks ago. Any way down to business I got home, Put a set of ape hangers on my Heritage and have been doing a lot of riding. Well this is my first Harley and that being said I don't know a lot about them. Well when riding everything goes smooth it idles fine and has plenty of power accept at full throttle, at full throttle she sputters and doesn't pick up any speed until I let up to about 3/4 throttle, what could be causing this? Sorry for rambling, just had to build up to it.
