Hi everyone, today I decided to adjust the chain on my rebel 500 because it was little loose. I've done this once before without any problems. Today after adjusting the chain I tightened the left lock nut and the tried to tighten the right one but it just won't tighten. Could it be that I over-tightened it and screw up the lock nut? Can I ride the bike like this /at least to the nearest shop/?
