So I recently bought a 2013 F6B. Love it. Previous owner installed torq loopz and cobra exhaust. I like the sound, not too loud at all, no drone, nice rumble(previous bike was a Venture and dead silent, lol).
1st question: Previous owner said he ran Premium gas. Cough cough, Do you feel that my setup truly warrants premium gas? I run mid-grade, and was thinking standard grade probably would be fine.
2nd question: Bike has 22k miles. Really don't know the maintenance story, but this winter I plan basics and all fluids. Would you keep the oem plugs with this exhaust setup, or change?
I'd really prefer to keep oem stuff, looking for advise from the pros.
Thx
