Traveller, I left my horn on and do honk at slower riders to let me by, but most of the time ther on 2 stroke race bikes and when they hear a horn they dont what to let me by, you just have to move them. in these races ther are about 8 rows of riders in diffrent classes that leave every minute, the faster younger rider classes go first and the old slower rider class go last so when your old like me your start on the last row and you will catch the slower riders and have to pass them fast to keep your class leaders in sight. Im only about 30 sec. a lap slower then my class leader. so most of my spare time is finding ways of getting 30 sec. a lap faster
