It's easy to repair broken clutch and brake levers, and they're stronger than original. Drill a 1/8 hole about 1/2 inch deep down the center of the two pieces. Cut a steel pin about 7/8" long. I use old spring pins, but a thick coat hanger or anything similar will do. Sometimes you have to bend the pin a bit so that the tip lines up with the rest of the handle. Use JB Weld to glue the pin into the holes and to fill the gap. Next day, sand it down and paint the handle with aluminum paint. If you're careful, the repair is invisible. New handles are cheap, but repaired handles are cheaper, and stronger.
