Tore my 120 r down to install a diff. set of cams.
this what I found @ 15,000 miles.these are the
SE lifters that come stock in the 120 r crate motor.
I ran these with the stock +.030 SE pushrods.

Can you give us some more details....

They don't look seized yet but the wear on the cam looks like they aren't rolling to good.

Not related to your problem but I'm thinking about getting a 120R. Why are you changing the cams. Power or drivability?

Jim,
What is the measured seat pressure, and nose pressure on those springs, with that cam?

200 lbs spring pressure.
to be honest I dont remember the nose pressure

I am ate up. just wanted to try them before winter hits. everyone keeps talking about how they would do.?
so i had to see. LOL

actually the cams are not hurt. looks like the case harding flaked off the lifter rollers.
there was no sign ..i just happen to open it up.

Did the TR-662-2's calling out from the shelf finally get to you?

    at 12,000. miles. Had to do a complete engine overhaul.

Certainly there are enough cases of issues with these lifters to just change them out preemptively before commissioning a 120r. I would use Wood lifters. I typically run 175# seat with those heads and at .65 they run about 415#

yes sir they did.
I got my main desktop down so I dont have the sheets and pics all down loaded.
basically moved everything left of 4000 rpms. 8-10 hp/tq at WOT.
throttle response feels better.

I cant remember that great place I put my paper work (so  I wouldn't forget where it was at)
the SE springs are advertised @ 200 in the MVA heads. I think Larry said that was a little heavy rating and they are a little lighter than that.
I also think he said the 500 nose at max lift was a little lower than advertised.don't hold me too it as I am going off memory .
I had my doubts about these lifters, but thought they would surely make a season.

[HD Street Performance]

Well 200-500 would be too high but nonetheless guys with stock 110s and B lifters are loosing lifters with relatively low miles and 175# seat SE255 cams.

No high ground to be found really for the lifters, SE or stock HD, but no need to run the pressure that high either as it just exaggerates the matter.

I have done some of these heads with the Wood 188# springs de-rated to 175# with Ti retainers and Wood lifters, corrected geometry, Baisley Roller rockers, coupled to a jackhammer of cams the TW408 and they have run rather quiet and have not broken lifters , one has in excess of 15K miles. Time will tell.

Did an extended warranty repair this summer, with the EXACT picture, though it was a 110"er.
His local dealer alerted him, that he was hearing engine noise, because the fairing was pulling the noises up to him.

FYI, I have 20k miles on my 110 with the Woods 408 cams, Woods springs, Hillside headwork and SE roller rockers. I definitely wouldn't call the setup "quiet" but it has performed admirably and so far without incident (knock on "wood"!)

[strokerjlk]

cams tested at rockwell 62
lifters at 58
my bad for mentioning case hardening. these rollers are not CASE hardened.

[HILLSIDECYCLE.COM]

Now comes the $64,000.00 question?
What oil, Jim?

I cannot see the side of the lifter are they stock lifters or the SE version lifters? The last 120R we just got in had some new items in it. Like the lifters, coated crank race, to mention a few.
