20w50 conventional in the cool months, getting ready to do the hot months switch to 50. 70mi/day, 31k miles later. . .all is peachy!
Oil debates...meh...how quiet do you really need it when you straddle a motor?!

I put in some straight 50w Valvolene Racing oil. Up till then I'd used either Syn3 or Mobil 1 15w-50. Personally I find the clatter reduction is not that significant with the straight 50. It still clatters more than I like. Totally stock 2010 RKC. The noise has been about the same since new so I think it's normal - just louder than I want.
I'd like to see Harley put some engineering analysis into this. Maybe they could change the cam profile with a quieting ramp or something with the rocker box covers to keep them from radiating the sound. Seems like they would want to do it because they could have a louder exhaust if they could reduce the noise from the valves. The total vehicle noise would be the same but more of it could be "good noise".

Since I have been unable to reply to the "lifter nose" thread since last night I figured I would try a new.
Wild Card posted "SON" (me) should do my homework on the reason syn is noisier. Wouldn't you know it the first site I went to was Mobil's. Wild Card should do a bit of research himself although he probably knows molecules better than anyone. Take a look SON and see what Mobil says about this. Also, you can find as many credible yea's and nay's on whether syn in noisier.
Maybe Wild Card should not be such a condescending dou&^ and look around himself. Oh I'm prepared for the scientific molecular explanation again.. Thanks Dr. WIld Card.

Any time . I see you havnt studied much, just come back to flap the jowls. All the down talk cuz I said son...wow your a real loose cannon. Personally don't give a damn but I am here...lets roll Jack.

It is funny that all I had to do is google molecular difference between syn and dino oil and I got pages of what I said...I just did it so it should still be in the google memory banck for you to study. I expect a full report in the morning...and no apology needed.

Ive experimented with both oils to determine which one quiets down valve train noise and although at first the dino oil made a small diff, after the miles started clicking it ( noise) was back so then your left with which oil protects best in desert climates and there really no debate on which one stays more stable. I haven't tried a partial syn oil and thinking about Brad Penn oil but dint want to start another oil thread! The only solution that makes sence is concentrating on the lifters.....I dint know how to do it but I'm studying and picking up that skill. Someone whose real good doing a DYI thread would be awesome.
