So I was out for a ride and suddenly **** hits the fan. Got off the bike and there was way too much slack in the engine side chain, turns out the tensioner had stopped tensioning. I locked the clutch in and peddled home normally. When I got home I readjusted the tension took it out for a test ride. With the clutch in it peddled normally, however, when I let the clutch out to start the engine I got some weird almost grinding noises and no start. Now, when I peddle/roll the bike there is no difference in resistance between clutch on or off. Every now and then it will catch for just a second and I'll get "turning over" sounds but then it will be free wheeling again. I am absolutely baffled as to what is going on.
