Not too long ago I made a thread about some engine bogging I was having. It turns out, one of my plugs had fouled up. Well now it appears to be happening again, and it has hardly been 200 miles if that and it's in the same cylinder. I'm running NGK CR8e plugs gapped to factory specs of .28. The only things done to the bike are 4* timing advance (running premium only) and stock mufflers, but they are cut, shortened and have some weird modified baffles.
What do you guys think might cause this issue? If anything, it started happening after the timing advance. I've been told that when advancing timing, I should slightly increase the gap and possibly run a hotter plug. Maybe I should try some CR7e plugs?
Thanks everyone!
