I recently did an oil change and went with the M1 15W50 and coming home from work Friday the topend was a little to noisy for me to be comfortable with. So I am going to go back to the HD 20W50 Syn. My question is do you think that I can just replace the oil in the tank or should I change the filter as well? I have only put about 50 miles on the bike since the oil change but I am concerned about what is left in the filter and how it will blend with what I put in. Also I was just going through the Exhaust comparison from American Sport Bike but I cannot get the sound clips to open in the PDF file. Anyone have an idea of what I can do to open them?? | ||

Just open them directly from the folder that contains the sound clips. Although there is nothing like hearing them in person. | ||

Isn't Insite a male enhancement product? Seriously, how is going from Mobil 1 50W to Mobil 1 50W going to change the noise in your engine? Multi-weight oils (such as 15W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. This page from the Sci.Electronics.Repair FAQ offers the following very interesting description of how the polymers work: At cold temperatures, the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up, the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C, the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot (Message edited by electraglider_1997 on May 27, 2007) | ||

Interesting, I put Rotella 5w40 in my Uly about 1500 miles ago. The engine sounded quieter to me than with, Mobil V-Twin 20w50 and Valvoline Vr1 straight 50. Starts and idles better when cold (such as it is) too. (Message edited by teeps on May 28, 2007) | ||

I use 15W50 Mobil 1 and the only issue with noise that I ever have is when I fail to wear my earplugs and that is a rare occurrence. I use these http://www.e-a-r.com/e-a-r.com/pushin_detail.cfm?p rod_family=Push-Ins%20Uncorded&ind_prod_num=318-10 00001 but I'm going to see about these http://www.aearo.com/pdf/customEAR_SS%20Final.pdf (Message edited by electraglider_1997 on May 28, 2007) | ||

I have to agree with the different oils make different sounds. I tried Amsoil and had lots of top end noise. (valve noises). Went back to Bardahl 100% Synthetic Classic V twin and it quietened down significantly. I tried it on both of my Buells, the tuber and the XB, same results. | ||

I cant find Classic v-twin from Bardahl on their site. http://www.bardahl.com/mods/gallery/gallery.asp | ||

Funny I didn't have a problem finding it on there at all. Try under Powersports it's right there. | ||

I think he is saying that none of them are called Classic v-twin and was looking for clarification of which one you are using. I took it to be the All in One 20w-50 since it is the synthetic one and the other 20w-50 is not. | ||

Thanks Jm for making my point. Those were the key words I was looking for(V-twin). |
