So yesterday i hit the 600 mile mark after about 100 miles of riding the bike. Twards the end of the day, i the bike sounded like pieces were going to come out of it...like it sounded all loose and out of adjustment. My guess is because of all the riding i did that day. Anyone else know what im taking about? It just sounded like it was seriously struggling...The engine sounded like it had pebbles in it and when i would start riding and give gas they sounded like they were just scrambling all over the place. Not sure if this is normal or not.
