This is very frustrating noise,as things heat up(as i drive the scooter more and more) the sound is more expressed,from cold start at beggining no noise at all.
It happens only on acceleration from 4000rpm.
Mechanic says that its the breaking caliper and cannot be fixed,because it working normal and the noise is normal,but i dont think the same

ah the joys of being death, all sounds good to me. I need a hearing person to drive my truck, I am sure it sounds awful. my scooter probably sounds worse. The lady said she wanted to sleep with me, I did not hear a word of it.
