The old saying, you can lead a horse to water but can make them drink the water! Well how many times do we have to tell you that if you have not replaced the plenum, DO IT NOW!!! I went to Biketoberfest and come across 2 Stallions (different places) that had broken plenums and one had the heater plug/cap split and leaked his fluids out! Both of these items have been discussed several times on this site. Both parts look perfectly good until they break so why not take the time and change them so you don't get stranded somewhere.
