You guys should have seen Ruby Wax on CNN.She says Negativity shortens your life so I am getting away from the bigotry and misery churned out on this forum to return to my happy and positive life. Based on what she said I guess you guys have about 3 weeks to live!

 

Don't let the door hit ya where the Good Lord split ya!

 

How many of my bikes were not suppose to make it unless I replaced half the bike with some other parts. None have ever had a major failure. My 07 96Tc was suppose to have a full page of issues. 75,000 on it when I traded it off. Last I saw it 85,000 on it still going strong never any real issues. Same with the TC103, The TC 103 highout put. Now with my M8. Betting it will just keep on going.
Lot of the stuff you read is from someone trying to make a buck selling you their version of the same ****.

 

Now that is often quite true BUT what is specifically talked about here is replacing the inner cam bearing with a new better bearing while your are in the camchest fitting a new cam.

This is LOGIC and good practice, not because someone wants to sell you a new bearing that may cost 5 to 15 $$$$ depending on where it's purchased.l

 

Timken bearings have been around forever and are tried and true. When I do a cam replacement, the timken will be first on my list of things to replace. Until then...... ride on.

 

Do wheel bearings fall into that "5 times better" category?

 

So if my bike is idling and I hear a whirring, metallic, grindy noise by my right foot, should I be worried?

 

The INA supports the cam at 21 ponts on a circle. The Torrington at 31 points. My INA bearing failed at 20,000 miles in my Low Rider, wiping out the cam journals. My only clue was a "scratching" noise from the right side of the engine while I was riding home from Sturgis, SD. The bearing cages were intact. I checked the crankshaft: .0015 run-out. I replaced everything in the cam chest with S&S parts except a Screamin Eagle oil pump. I didn't reward HD for saving a buck on a crappy design. I'll post a pic of the chewed up cams if need be. If you are in the cam chest, replace the bearings. If a roller had found it's way to the crankcase: Mega-buck repair wit engine removal.

 

I had the first year Evo bike that went to INA bearings. I changed cams as much as anything to get rid of that bearing. They really did cause numerous failures. Fast forward to the TC and the bearings were still INA but much larger diameter. You didn't hear of many failures with them. In fact, Andrews actually suggested leaving them alone. Not sure anyone other than Andrews did that. The last TC bike I changed cams in was new and I left the bearings alone. Never had an issue but maybe I was lucky. I will leave my M8 stock. But thankfully I can add the cam bearing as yet another item to potentially fail. Along with lifters, oil pumps, sumping, leaking oil jets and God only knows what else. I haven't had an engine part related failure in an automobile in literally decades and have kept them all for around 150K. Who knew HD would need rocket scientists to engineer such simple components as oil jet gaskets?

 

just spit coffee on the keyboard, you forget what company your talking about here, they have a very LONG history of getting **** half right and cheaping out on key components. Birthing pains for this thing will make the troubles the M8's have had look trivial by comparison.
