2008 zx6r, i put new spark plugs in my bike. Buddy of mine says i should put iridiums or something like that in it that has more spark and burns hotter. Advice? My bike stinks like gas, not horrible but u can smell it. This was a cheap option i was willing to try for now. I google searched my bikes plugs and went with the exact stock ones. Let me no what yall think. I appreciate any advice or past experiences. Really if i aint riden im on here lkn to improve and spoil my bike.
