Just a tidbit. a buddy of mine bought a 08 Screamin eagle ultra. He had it 2 weeks and the throttle side grip was coming off. He called the dealer to inform them and they told him not to try and force it back on. Bring it back and they would fix it. There is a relay, sensor or some electrical component in the throttle sleeve that if it gets damaged, is a $300.00 part. I'm not an expert on this just passing the info along. If someone instructs you on how to change them, keep this sensor in mind. :up:
