Another whining noise constitent with RPM

[i8avet]

I went on a 300 mile ride today. About 75 miles to go I topped off my tank and when I started my bike there was a loud whining noise. The noise is constant with enging rpm. Was never there before. I pulled the primary because I thought the chain rubbed through the guide. Not the case. Slack is good, not too tight not to loose. I put a stethascope by the cams and thats where it seem to be the loudest. I have no mods on the bike. the bike is a '99 electra glide ultra. any ideas?

How many miles? 99 bike... does it have the original cam bearing?

[i8avet]

I think I would be pulling the cam cover & checking for any discoloring of the internal parts. It maybe a bearing on its way out. Check the mesh on the chain.

i pulled the cam cover and half of the orange guide fell out. The spring tensioner on the bottom is bent and cracked (probably from riding the chain). thanks for all your input. UPGRADES HERE I COME!!!

Inspect the rear bearing surface on your cams good too. My inner cam bearings on my 06 started taking out the cams at 32,400 miles.

1999 is either an EVO-engine or a Twin Cam.
And the first generation V-twin was called the F-Head (untill 1929) then came the Flathead, Knuckelhead, Panhead, Shovelhead untill 1984 and then the EVO, to be replaced by the Twin Cam in 1999.If you are confused about all those names look on Facebook at Iron Butt, more than 1.000 pictures from 1903 untill 2013. Please send a picture of your H-D on my Iron Butt-account on Facebook http://www.facebook.com/iron.butt.9?...#!/iron.butt.9

If you Look at the front frame down tubes (squating from right side looking thru to left), you will find a sticker saying Build Date.

IF it was Built in 99/dec. You have the problemed BALL bearing in the rear cam plate to replace also...
The beariing only got replaced by HD when it totally went out.
(I did mine when apart)
HD promised way back when they became a Problem of Blowing up,,,,to replace it for free IF it exploded on any owner of date...BUT when I sent a owner to get their Warranty,,, "Sorry Charley" too Late... So WE have to replace them... Better before they become a problem.

If it has the 00/jan or later date, that bearing is a Roller and should not pose a problem.

The Shoes, (two places), one in front as you have found and the other in the rear of the cam plate
(condition can be seen there with using a small dental mirror if cam-plate not apart)

The older bikes do fine Switching to Gear Drive cams.
IF the cranks run-out is about .001 and max of .003 (I prefer Less than .003 and find Most at .001 to .002, then like going gear drives on the cams.

Another replacement Usually done at this time is the INA (engine cam bearings) changed out to the full needle roller style. Not expensive but Careful removing and replacing them.(special puller and driver are good tools to have)

Easiest and works Good:
IF you go with the Hydraulic tensioners,,,,, IMPROVED cam-plate and High Volume oil pump with other parts in the HD "KIT"...
You will be updated to the newer style cam tensioners that HD uses today but still have the 4" stroke.

If you need or want More information, I'd be happy to answer any questions on this as I Had a 00 early 1/2 year model and did Many good things to it.

Looks like your on the right path.
I don't know the intake close on the cams you are using...

Need to konw that for My opinion... Intake Close* has a lot to do with the compression NEEDED to operate the motor. My prefrence= 180 to 190 lbs of compression seems to work best for todays 91 junk we get. AND the alititude you are from sea level

IF your just tossing pistons into the mix at 10.5 X 1, Careful and ? on the Squish distance and CC in/on the heads.

IF intake closes about 40 -46 * ? you may be Okay..
Give me the * of intake close and I'll run the numbers you are showing here.
