Just returned from a 1450 mile ride and at about 600 miles to home the Evo developed a whine from the front left side of the motor. It is stock with 50,300 miles on it. 1996 80 Evo. I had to have a new stator installed at 48,000.

I have a lifter tick now as well.

Is that noise a bad cam bearing?

Any help would be great.

Thanks

 

Well, your year has the weaker cam bearing. A new whine noise and a new valve train noise in a motor with 50K on it is highly suspect for cam bearing. Others have reported the cam bearing noise sounding like it came from the left. 50K miles also is when others have reported the cam bearing going. And that's about it for lifter life, so it needs to come apart anyway.

 

Sounds like cam bearing noise to me... mine was howling like something else, and it already had a chunk broken off. Thankfully I found every single little piece and didn't have to split the case. You're overdue for a lifter swap as well. Time to get to work I guess...

 

Mine had that very same 'whine'.. Everyone said it was normal! I built my motor, (not because of the whine)and I put a open belt drive on, the whine is gone now. Well, I cant hear **** any more over there.

 

I took it to local Indie shop and at first they it was normal but, then the tech took it for a ride. As like everyone here as said, definitely cam bearing. Yup, looks like lifters, cam check, and new bearing. I have read a lot posts today. Looks like the Torrington bearing is the prefered bearing but, a couple of different lifters recommended. harley "B", Andrews, and S&S.

Any thoughts on the lifters?

Thanks everyone for your replies!

Johnson Hylift lifters....

 

Did you put the B-138 full compliment bearing in?
Torrington B-138 or Koyo B-138, they're both the same... whatever is easiest to get. As far as lifters go, I have Johnson Hylifts in mine and they work great.

 

My thought is, if you're changing the cam bearing and lifters, you might as well change the cam.

Torrington in mine...

And the Op, I have used V-thunder lifters on BOTH motor builds, Not one problem!

 

Thanks again for all the great info! As I read thru all of the info on this endeavor, I didn't see any mentions of oil pressure concerns. I did not see any oil pressure change, just thought I would ask if there were any concerns, or thoughts about that??

Thanks again!
