I bought a 07 zx14 this week, ran great on test drive and loaded it up.
It's stock except M4 pipes on it. I was only on it for a bit but it had a small backfire when backing off throttle.
It wouldn't start after I got it home and sat for a few days, I pulled the plugs and they are black. I'll replace them in the morning I think that'll fix the issue but want to make sure this doesn't happen again.
I read about the PC but am concerned I'll mess up the programming as I'm not a Mecanic or tuner. Is there a more ample fix or any insight would be awesome.
Thanks guys,
Aren
