I'm confused as to what's moving or not, if the bike will not move under its own power it's fairly simple to follow back, chain, front sprocket, clutch, gearbox? That’s The order I’m trying to do. But until new chain comes I’m just sat waiting. I mean excuse me if I’m wrong but if the chain was so loose as I described and I sat on bike and tried to move then I’m assuming it just wouldn’t have to tension to pull. Which is what I experienced before? Like I said before I didn’t know the chain shouldn’t have tight spots so I prob tightened it to the last of its life followed 4 hours of ragging it round Yorkshire Dales just battered it to death? The only thing I don’t understand is when I put in gear I can leave it idling there without it stalling.
