Ok, so I am new this forum and I have an 07 softail standard. I got this bike a couple months back and have changed all of the fluids. The bike runs great, but I have some questions about the noisy primary. I have changed the fluids in the primary twice. the first time I put synthetic 20w50 and it was still loud, so I decided to try Redline Shockproof. I think it is slightly quieter, but still pretty loud, especially after the bike warms up. So, the primary kind of sounds like a sewing machine when it is still warming up, but then it gets progressively louder when it is warmed up. sometimes, the sounds is pretty pronounced when I am coming to a stop and downshifting. I have also noticed that it is a little louder in 3rd than 4th, not sure if that means anything. On top of that, if I really get on the throttle I get a kind of high pitched noise from the primary have no idea why that is? I am not sure if I am overreacting to the sounds or if I am noticing something that may be failing? As I stated, the bike runs just fine, but I am not certain what to about what I am hearing. Any help on this would be greatly appreciated!!! Thanks.!
