Why do I keep breaking footpeg springs?... rrr.

So, I have now broken 3 springs on my left footpeg this year. There seems to be nothing abnormal/defective about the springs when I put them on... the pedal seems fine - it is a Fastway F3... but the spring keeps snapping in the same spot where the loopy doodad end touches the frame mounts. See the pics. Why is this happening? Any suggestions? Or alternatively, a CHEAP source for springs? Thanks.

Maybe there is a sharp edge right there that wears a grove in the spring causing it to weaken. If so you could file the edge to smooth the it off or try a piece of tubing over that part of the spring to cushion it.

Try putting a glob of RTV on the spring.

Old trick snowmobilers use on the springs holding pipe and exhaust can together, RTV kills some of the vibrations that wear on the springs.

This. I bet there's a burr on that edge.

I'd soften the spring at that bend, that will cure the breaking issue.

Submerge the spring in a pan of water so the bend sticks up above the surface 1/2" or so but leave the coil in the water, just so you can get heat at where it snaps, then heat it with a propane torch just until it starts glowing and then let it cool naturally and it will not break on you.

is the peg hitting the spring when folded and smashing the spring?

I don't think so.... at least not when you move the peg by hand...

I think the plan of attack will be to lightly file the frame mount and paint. I think y'all might be on the right track with the burr. Thanks.
