last night went riding on my 06 500 rubi. Well i took the spark arrester out to clean it and decided to ride with it out cuz it sounded cool. About an hour later, i noticed the inside of muffler was blazin orange. Is this normal or did this happen cuz removed the spark arrester. After I discovered this i put the arrester back in. Just curious, do all mufflers get blazin orange inside? Tit ran fine and my plug is slightly dark colored.
thanks
