5th gear noise is GONE!
I must preface this post with a "this is no BS". At 1000 miles I went to Amsoil in the crank and primary, kept H-D in the Tranny. From 1000-5000 I began to hear the "bird chirp" in 5th gear. Got to where It was very pronounced. Didn't have a problem with it, just very noticeable. Just did my 5K service and stayed with Amsoil in the crank and primary, but went to Amsoil Severe Gear in the trans. I kid you not, 5th gear now sounds like all the others, chirp is GONE. I'm up to 5700 miles now and gave it a week to make sure before I posted my findings. I'm a believer. Lucky for memy H-Ddealer carries Amsoil for just cents over what I could get it from an Amsoildealer but with no shipping costs, so it's a wash.

RE: 5th gear noise is GONE!
Tell my why then my service manager where I bought my bike ( I guess I understand why he tells me to stay with regular Harley oil but he is also against Syn3 which I know from reading on here most do not think it's a true synthetic) but also two local independent mechanics think I should stay with Harley products. I tell them all the good things I've read about Amsoil on here but they advise me not to go synthetic. I know it's my decision, but wonder why the mechs. are so against it. One did tell me that bikes with a lot of miles will find a leak with synthetic if there is one to find.

My Harley dealer told me if I used Amsoil in my bike it would void the warrenty. I still us it anyway because when it comes right down to it, Amsoil is the best insurance you can get for your ride
