I've got an 05 Electra Glide that I'm getting ready to have a 25K service done. I've got the HD service manual that lists everything that needs to be done but is there anything that the manual doesn't list that I should consider doing?

Also, I was checking my oil this weekend after a short ride, bike was hot, I noticed the oil on the stick was clean but it looked like it was bubbling. Almost like it was oxygenated. I'm running Amsoil 20/50 and its been extremely hot here in NH the last couple of weeks. Any ideas or suggestions? I know... I know.... Check my oil BEFORE I ride!!!! Got it!!!!
