Okay, first harley. I got a Nightster '08. as you know it's EFI No carb. It's my first EFI bike. I want to get some straight pipes. Do I HAVE to get the stage one cleaner? What else will I need?
No you don't need the air cleaner right away from what I have heard, but as soon as you get the cashIwould get the better air cleaner and a fuel management system like a PC III or Sert.
This always gets asked and I'm sure I asked back in the day myself but if you want your bike to run right get the air cleaner and fuel management. What brand you choose is up to you
