Hello I’m from Moses lake wa I bought a 2007 Yamaha 660 and it ran fine but I had it in my shop for about 2 weeks and I started it up it was having problems starting but when it turned on it was making a grinding noise and also when I went to shut it off it wouldn’t shut off but when it finally did I tried again and it wouldn’t turn on and my finger was off the button it tried to turn on by its self
any help would be grateful
