Some things never seem to change. My old '94 has had a valvetrain rattle/tick in it since it was factory rebuilt back in '02. I've had it back to the shop over and over again, only to have the techs stick their fingers in their ears and tell me they can't hear anything.
I've changed lifters but it didn't help.

Funny thing about the oil system and oil filters. When the 5 micron filtering agent in the oil filter starts getting plugged, the filter bypass opens and unfiltered oil now goes thru the system. Could be something in the lifter(s) Just wondering if you aren't using the correct filter filter, or the oil pressure relef valve is a little weak, not maintaining the correct oil pressure after the oil reaches operating temp.

I sorry I don't buy that answer. almost everyone I talk to that has 10-15k mile has a lot of what sounds to be lifter noise. I had it on the 05 EGC and I have it on the 09 EGC I have how. I started with dino oil until the first 1k service and switched to syn3. somewhere around 10k I started noticing the lifter noise.I'm at 16k now. I switched to Redline in all 3 hole the last service and it may be a slight bit quieter but not much. I've asked the very same question on this forum and was told,
1) it's a harley get used to it
2) buy earplugs
3) wear a helmet
I love my Harley and wouldn't get anything else, but it it is a little hard to get used to it sounding like a Ford diesel. I've had people tell me they tried throwing money at it replacing lifters with no change. The only answer I can come up with is I wear a 3/4 helmet and keep the radio loud

I forgot about (lugging your engine) running at low RPM's with lower oil pressure. You will not get as much oil to your lifters. But most time it's from run old burn oil. Running the wrong weight oil to save money being cheap about your bike. The only time my bikes will make any noise is with low oil or burn old oil. You could change that oil today and sit in hot traffic bumper to bumper with out an engine fan tomorrow and have burn that oil.

You know it's funny that for all of the replys, no one has even suggested that there could possibly be a colapsed lifter...hmmm. Now, I'm no tech, but it seems to me that there's a lot of... ah, just add crap to the oil, change the crappy OEM parts with aftermarket parts cause original parts suck....or turn your radio up louder......I thought this was a forum were people who are or know someone who's having the same problems or issues could get an inteligent answer or at the least be steered in some sort of direction as to correcting thier bike problem/issue. Oh well, at least some of the replys give a guy a good chuckle....

Well......the bike spent a couple of days at the dealer for a few things and low and behold they are going to replace the lifters because they are leaking down too quick......thanks for all the interesting advice everyone had to offer.
