Will heres a quick brief i'm about to got to work. Went for a ride after my bike a sat for a few weeks, warmed up the bike took off slowed down and bike shut off. could not get it to start checked everything, and then went to start it again and now when you go to kick it, it doesn't go all the way down and you can here it hit in the bottom end. I'll pulled the valve cover and the timing chain is still intact. I'm thinking a broken rod??maybe let me know what you think before I open up the gearbox. It kind of feels like its in gear even in neutral.

Found timing chain was to loose and binding.
