In "World's Fastest Indian" Burt referred to his many broken engine parts as "Sacrifices to the God Of Speed". I have such a "Wall Of Shame" and some pics of the latest addition are attached.
A few months back I dropped an exhaust valve--the tip came off the stem where it is notched for the keepers. When I pulled the head I found the valve jammed firmly in the seat at a 90 degree angle minus the stem which made its way out through the port and into the header.
See the attached photos and notice the indentaton on the underside of the piston just above the "JE" logo. I have epoxied the valve into the deep groove it made in the top of the piston for the sake of history.
I recently got through rebuilding the engine and the only thing that died was the valve and the piston. The rod checked straight and the crank and block passed a crack test, though I did have to sleeve the one bore.
