Engine noise?

Any one having any problems with the self adjusting lifters? noticed the engine getting a rattle after the 1000 mile service and started getting a little louder. just change the oil to 60 weight and it seemed to help.
Is this sound normal or do I just need to put louder pipes on?

I hope you mean a multi-viscosity 60W oil, something like RedLine's 20-60W. I'd worry straight 60w oil would be too thick (especially during start up in anything but solid 80+ degree weather) and could be causing the lifter noise problem. Normally on a street bike you'd use 20-50W or 20-60W.

I did a quick internet search on straight 60W cycle oil...per Amsoil its normally used in ultra-high HP bikes(see description) but not in daily road cycles.

Much older Harleys had larger clearances in the engine and needed 60W it reduce blowby the rings, hog piss(oil leaks), etc. But modern TwinCams have smaller oil orifices/passage ways. If you running straight 60W in your TwinCam due to engine heat in Florida, I'd think about getting some type of oil cooler instead and reverse to 20-50W or 20-60W. That way you have good oil flow at start-up.

If you are running straight 60W you're asking for trouble. What type of oil were you running when you got the noise? I ran HD dino until my 5k service & now run Redline syn. Redline makes a 20/60w also

I had the 20/50w until the 5000mile change. The techs at Orlando said they all use the HD SAE 60 in their bikes during the summer months in Florida, I have had no problems with starting the bike so far. The noise is less with the SAE 60 but still noticeable. What do ya think? lifter issue or am I just being. paranoid?

oh, forgot one thing, The bike is garage kept at night where the temp stays between 75 and 80 degrees. When I leave work temps are in the upper 90's and some times in stop and go traffic, that is another reason I went with the thicker HD oil.

For me I would do the 20/60w. I agree with SharkNose. Do whatever makes you happy & whatever works for you.

...and straight 60 in cooler weather can put alot of strain on your engine. Harley's are "wet-sump" so as you crank the engine the crank wants to stay put and connecting rods and piston want to move causing - at best - premature bearing wear, and at worst, blowing the engine. Sraight 60 is like grease at cooler temps. Hope you already flushed it, bro!!

I reviewed my 2008 Owners Manual and do see that straight 60w oil is an option when the lowest ambient temp is 80 degrees, so I can see where the HD techs are getting this info from (and the basis of my earlier comment on temp above).

Since I don't use that heavy an oil where I'm at, I can't provide any feedback on lifter noise. Perhaps some other southern riders can chime in on if they experience more lifter noise when running 60W.

But I will add, is this lifter noise more more noticeable on start-up, I'd suspect its the thicker oil.

I have less noise with the 60 while riding and at start up. when the bike gets hot is when the noise is most predominate. The 2011 owners manual states to use sae60 in temps over 80

Have you changed anything else on the bike? Even changing the windshield will make the bike "sound" different. When I first put the lowers on my bike, I thought the engine was shot. All I can say is these bikes make a lot of mechanical noise, but if you feel something is not right it may be worth your piece of mind to have it checked out.

I have heard of very few issues with the later model lifters (or valve train for that matter). But there can always be a defect, these machines were designed and made by men (or women).
