If I read your mail correctly, the problem was on the Israeli side. Is that correct? I would be surprised if the problem had been on the Jordanian side: Many bikers have crossed Jordan, either coming from Syria or from Egypt without any problems. And which border did you try to cross? Allenby (King Hussein on the Jordanian side) is very different from the Northern Border (Sheikh Hussein) or the Elat - Aqaba crossing!
