Nothing, but my brother and I went to the motorcycle museum in Iowa. Only 2 750's, a K0 labeled as a K1 and there was a 750 chopper too. a lot of really old stuff. Elmer Trett's fuel bike, a twin 650 twins yammy bonneville Vesco bike. A twin water buffalo drag bike run dry. Lots of really old stuff, Indians, several vincents, many I never heard of before. A blacksmith shop with old bikes, hill climb section, flat track road race, well worth the 7 bucks to get in. Next June they are moving into an old Wall Mart building.
