Strange exhaust sound
Hello, i have a kawasaki er-6n 2006 with a mivv exhaust and last week it started to make a strange sound (like a something is hitting the exhaust, a squeezing/tickling sound) thru the exhaust but mostly when heating, decelerating or being in neutral, it started out of nowhere when i was riding and it looks like the sound is getting louder, does someone know the reason or someone encounter something like this before ?
