I have 2013 m109
First, I had some weird clutch like power is not transfer fully to the beast. It would revive up and moves slowly but not huge power after letting the clutch lever all the way out. Then It was hard to put it shift to drive. I had to play with the shifter up and down couple times and moving the bike back and forth until shift!
I was wondering if it only could be only bad clutch plates or the loose nut common problem. what are the symptoms of the loose nut?
