Howdy,

I've seen a number of 73-74 CR250 frames break right at the foot pegs. When I've looked at them it appears that there is a fair amount of rust occuring inside the frame tubes at that point, which is also the low point of the frame so water accumulates there.

I'm thinking of drilling a small 1/16" or 3/32" hole at the bottom of each tube right at the footpeg mount to let water bleed out and hopefully reduce oxidation and weakening of that section of the frame. I'm just a little concerned that doing this may instead weaken the tube by providing an area for a stress fracture to start from.

Has anybody done this or have an idea whether this would be safe to do? Thoughts good, bad or indifferent?

TIA,

Loren

I tried this on my 73 CR250 frame but cracks started from the hole and eventually circled the entire tube until it did break. My aluminum stand wore a hole in another frame on one side which did the same thing. Better to plug the openings where the water gets in is my guess.

Hi Jerry,

Thanks for the note. Guess my worries were founded afterall. I'll try something else.
