The Torrington is only about $7 or $8 these days, and they are available from any bike store or internet site. I'd replace the INA bearing even if I were running a stock cam... it's cheap and you will never have to worry about it again!

I am under the impression that Timken bought out Torrington so it should be the same bearing just with the new company name.
I recently put in a new cam and went with the EV13 because it seemed to match my style of riding better. So far I am very happy with it...i've only put about 1500 miles on the new cam but so far I feel better pull at the low end, cruising on the fwy at lower rpms and much better passing in 5th gear so I don't need to drop to 4th to really accelerate on the freeway.
If you like to rev high and race then this probably isn't the cam for you...I think it comes on around 2000 rpm or so and the sweet spot seems to end around 4500 rpm where some of the other cams stay on higher up in the rpm band.
It works for me because I ride lots of 2-up, don't race it, and take a few bigger trips each year so it is great on highways and freeways....I really can't compare it to anything other than stock but I sure wouldn't go back to stock. ...only negative, and probably the same with any higher performance cam, it is a little noisier than stock.

Noisy valve train/rocker-box on evo
Appreciate all the replies to this thread. I went to look at the bike again and am close to pullin the trigger. I fired it up again and rode it for about 20 minutes. What I hear seems to increase in loudness after about 15 minutes and what I hear is a tack tack tack tack noise that increases-decreases with engine rpm. It is coming from the front cylinder, I think. It is not general valvetrain noise from all moving parts. It is most prevalent when slow cruising and letting off the throttle slightly. The owner is being straight with me, says that he too hears it and has replaced the lifters and pushrods with S&S adjustables, made no difference. No internal mods other than that. I think it may be normal Evo noise and once I convince myself of that, I'm going to buy it. Its a nice bike. Thanks all. And any other opinions welcome of course.
Forgot to mention the bike got a fresh oil change with 20-50 synthetic before I rode it.

i ride with a lot of guys that have evo engines, those that are ‘96 thru 99 are generally much quieter engines. I own a ‘95 and recently the engine began to make some nasty sounds in idle so had the local HD dealer open her up to discover a fused cam shaft bearing and worn camshaft. Both were replaced by Andrews v27 cs and bearing, also a new set of pushrods from HD and 4 new Feuling hydronic lifters. While my engine was a relatively quiet one prior to all this, now I have top end tappet noise when engine warms up, performance is good but the exhaust and crank noises are changed. What can I say? I am concerned to some degree but not sure what to do next. I am using Screaming Eagle oil but seriously considering an alternative! Cheers :-)

You might also want to take a look around my website, some top end noise has a surprising source

Same here with my '93 FLSTC. Still, I plan to change the cam bearing this week.
