1) Crank arm bolts tight (really tight). If they're loose and you've ridden it when they were loose you may want to pull them and check for damage--especially if it's a square taper BB. If you decide to pull the cranks you might as well do step 3 now too.
2) Pedals. Remove 'em, grease the threads, re-install.
3) Pull the cranks. Pull the bottom bracket. Clean, grease. re-install.
4) Check the chainring bolts to make sure they are tight.
5) Still noisy? Try rebuilding the pedals.
In my experience, a popping sound is usually a loose BB. But then I religiously check my crank-bolts (a torque wrench relly helps here and avoids over-tightening). |
