My bike is acting like it has fouled plugs. 09 fxd with the techlusion tfi. I pulled the plugs and they were all black so i changed them but it's still cutting out. When i maintain one speed it starts cutting out but when i get on it it seems okay. all the wires on the tfi are still good, battery was still tight, it was on empty earlier but i filled it up. It also idles realy low now and doesnt pop on decel anymore. Any ideas? Kinda bummed because i just got it back from its first service a couple days ago and it rode fine but just started acting up today.
