Thanks for the reply BUBBIE. the bike was mfg. April /00. It has 50k on odometer. I have put 350 miles on it since i bought it . any mods are unknown,but my son who has had a harley for some time seems to think it has none. I put a new set of lifters in from a shop in fort worth that are supposed to hold more oil. may have helped some what. has Royal Purple 20-50 syn oil and HD filter.Noise seems to be directly from the lifter covers.rockers seem to be in good shape. Cannot get any info from the guy I bought it from. He just says it has always been serviced by HD Dealer.
Thanks again

sounds like bad lifters in a v/8 Chevy
IT MAY BE one of the NEW lifters IS BAD...
WELL HAPPY DAYS FOR YOU!!! on the model BUILT date
THAT BUILD DATE tells me that the NEWER STYLE ROLLER BEARING has been put in by the HARLEY people (second 1/2 of year and up)...
There is a SE lifter B that people talk about... a HD part.. as being GOOD....
I would put a oil pressure gauge on it to check pressure.. IT should not go below 8/12 lbs at an idle when HOT... If it quits tapping when IDLE is lifted up around 1500RPM or so
,,, I would say not enough oil SO CHECK with a pressure gauge...
I had a 2000 early year and did a LOT of changes THAT HARLEY NEEDED to do BEFORE they did on the newer bikes 2007 and newer...
YOU can change a lot of things NOW that COST me a SMALL fortune back when I changed out stuff..
HD(99 thru 2006) didn't have the BEST oil pump and the RETURN of (sump) oil didn't get pumped back into the oil tank and LINGERED inside the CRANK HOUSING and was a main culprit for the FOAMING at the air cleaner and thru out the engine....
too much oil in the sump area causes a BIG DRAG on the performance of your motor.. that is why the new style pump offered by HD.
HD HAS a good KIT out NOW that CORRECTS the problems with oil pump, chain drive cams, and the tensioners..
the newer system IS NOT PERFECT but cost about a 3/4 + LESS than i paid for the improvements on mine...
IF I had a 2000/06 bike again I would go with the FULL HD KIT and get the BETTER oil pump, newer style cam support plate and the HYDRAULIC cam tensioners...(last longer and trouble WORRY free from the SHOES that destruct and cause DAMAGE)
THAT KIT would make your bike RIGHT UP TO DATE with the NEWER style of today...(better oil flow and LESS noise like the old style oil pump)
If you ever decide to convert, YOU can get a lot of information and help from KNOWLEDGEABLE people on this site..
My FEULING oil pump and lifters were 450$ along with another 300 or so for the DELKRON cam support plate and 750$+ for the 570SS gear drive cams i went with...
DID you go with adjustable push rods and were they adjusted right? MAYBE check that first...
HOPE some of what I spouted off on can Help you..
signed....BUBBIE
also look at another guys problem under ENGINE KNOCKING by Chase1
i think he has the BAD bearing...
maybe this time...
