Hello together, yesterday I bought a Kawa er5 bj 2004. Unfortunately I noticed only at home a funny cracking or rubbing when the machine is in idle.It sounds like I’m making the gear in, this noise comes sporadically. from the driving behavior everything is top and nothing unusual to recognize. I now contacted the previous owner. He only said this was a vergader motor and at the age completely normal…I am afraid that there can be something more serious behind it. e, unfortunately I’m not all to experience and novice driver…I hope someone can help.lg
