Well...it took some time to happen, five years, but if finally happened...my frame cracked.
Here's a little history with it.
In 2007 I was racing my '01 Honda CR250 and wrecked it...4th gear pinned. Well, as the bike went down it jammed the lower triple tree to the right, crushed the throttle cable, embedding the cable into the upper down tube.
For a number of years the damage from the cable was visible but no cracks formed from the damage. Well...fast forward to today and while looking over the bike and noticed a cracked that formed over the damage and must have happened from the last ride.
To make a long store even longer has anyone successfully repaired a Honda CR Frame? Does anyone know what series aluminum it is? I've seen lots of threads on the aluminum framed Honda's, especially the CR500AF, but no one really going into any details in what the base metal is or which filler rod was used.
Here are two pictures of the crack; the lighting isn't all that great but it should give a good idea of the crack. These down tubes appear to be of a real thin wall thickness; around 0.032 inches.
