Engine and Drivetrain 2008 backfire and noise from belt housing May 20, 2015 Once my bike warms up I am getting a noise from the belt housing area (sounds like hocky cards in the spokes of a bike) and my bike seem to hit a rev limiter whn driving even at low speeds. The bike will also backfire when this happens. Any ideas? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
