My first time opening up the valves. I dont know what possessed me but I thought I could use the kickstart to put the engine in TDC. I forgot that I already removed the chain tensioner and it made a grinding noise. The chain tensioner will not tighten the chain whatsoever now.

Id imagine the chain came off the crank at the bottom or is wedged in the guides.

Pop the left side cover off the bike and look in. Drain your oil too.

You need a service manual at the very least.
