Just bought a used 2003 Prairie 650 with 1200 miles on it. The front end has an annoying loud whine that starts at about 5mph and continues at all speeds whether accelerating or letting off the throttle. Has anyone had this problem or any ideas on what the problem could be.

650 engine noise

You probably have noticed the noise comes from the right side of your bike right? Well, I am picking up my 2002 650 from the shop tomorrow and it had the same problem; the engine brake mechanism had to be replaced. My bike has approximatley 1200 miles and the mechanic said it is quite common with this mileage to replace the belt also so I did.

Good luck, it's a BAD machine!
