Hi guys,
got a bit of a issue:
my wife has an Aprillia Trail, which uses the Yamaha 660 motor.
The bike has 20 000km on the clock.
We are running fully synthetic oil
About 1000 km back the motor became very noisy.
It has a rattley noise that sounds like it's coming from the top end.
The motor has been removed and opened.
Everything looks good.
No glitter (metal) in the oil.
Nothing looks like its wearing.
Iscrhere something that I could be missing?
