Any insight? My bike lost most of its power, I wasn't able to open the throttle wide without the engine dying more, and the engine sounded "muffled" all of a sudden with a bit of a rat-tat-tat sound like something was plugged up. After riding for a minute or so, something seemed to "break free" and the power came back as suddenly as it went away. 550 miles total on bike. Thanks in advance!!
