i have an 06 streetglide. every once in a while, when i am down shifting and coming to a stop, my rpms drop down to about 600 then to 0 and my bike dies. i can hit the start button and it will start right up and i might not have a problem with it for the rest of the day. it seems to happen more when ive been on the freeway, starting to exit and coming to a stop but it has also occured when riding in town making muliple stops.i've had it put on a dyno to see if would acted up but no luck. also when coming to a stop and the bike starts to loose its idle i can hit the throttle and keep it going but as soon as i let off it dies untill i start it back up again and then it idles perfect! ive spent lots of $$$$(new race tuner,etc.) with no results. does anyone know what could cause this, thanks.
