I have a rapid thumping on my '13. It's very strong while going constant speeds or downhill, but here's the catch: If I pull the clutch in it goes away. Tires, chain, and sprockets are good. I feel the thumping in my handlebars and footpegs when in 6th gear and within the 5-7k rpm range. I?m I?m accelerating or decelerating its very hard to notice it, if at all. Any ideas what I'm looking at???
