Been watching. Nice bike JW.
Bad on Hastings for leaving folks to guess. Speaking of guessing, I guess I got lucky on my rebuild  :nix:  All is good so far, I'da been pissed to have to haul that apart again for someone elses short comings.

Hey Gary,

No instructions AT ALL. Just three pouches in the folded paper pack, indicating Top, Second, and Oil rings.

Regarding the info on that Hastings link, look at the second line:

"Rings with a bevel on the inside diameter but no "pip" mark or dot must be installed with the bevel towards the top of the piston."


That is what threw me. The S&S sheet I have said the same thing. With that coating on the rings, I could not see any pip mark. So bevel side down. Which, turns out, is incorrect.
 :kick:

Here is what Hastings used to supply with their ring sets:

A little hard to see clearly, but enough to see it has some detailed instructions how to install and check fit. Now, nothing! And you can't see the pips til ya wipe the crap off them. And oh jeez, they don't mention anywhere to do that either!!

I do owe Hastings a phone call at some point to lodge my grievances.

That's a crazy amount of oil sitting in that cylinder, and that's after at least 24hrs of sitting.  But dang that rear cylinder was pumping out a crazy amount of smoke.   Can't believe it kept running, been a long time (if ever) since I've seen that much oil smoke...

Fingers crossed the flip gets it done.

Personally, i would have done two things.
Get a new ring pack as this one is been treated dubiously.
Plus it has been run upside dwn.
I have no idea what that will do when that much fire and oil is leaked past them.
Rings are supposed to be gas operated one way or another.
They expand when the explosion goes off in the cannon.
These ring(s) were not installed correctly so lots and lots of fire and oil rushed  past
creating a fire that hell would not have
It has had some abuse from those somersaults.
Like i said B4 get a low drag pack about the 9 to 14 lb variety.

Going to trust my machine shop dude on this, who evidently BTDT before. He said if I only put 10 miles on it like that, just flip 'em over and go. What the hell, worse comes to worst I tear it down again. And put it back with Axell 97" cylinders.
 :SM:

Also, the 2nd compression ring doesn't see the high pressure from combustion chamber. Was reading that the 2nd ring is really more about keeping oil out of the combustion chamber. And as I know all too well now, if not installed correctly, IT DON'T!!

Too late tonight to fire it up, but is ready to go for tomorrow. Maybe a good day to play hooky? Er, uh, no, I meant "work from home"...

The 2nd ring is tapered. Rides over the oil on the way up & scrapes it off on the way down. Upside down it's just pushing the oil up into the cylinder. Flip them over & ride it. You won't have any problems.

So are you saying bevel down or up on an unmarked ring?    :scratch:

Well Sha-zayam!

Although it's been a little bit of a painful lesson, at least I can say, without doubt, what that second ring is for!

So all I did was tear it apart, flip the second rings, put back together.

Before: smoking like a, well, nothing I can think of. pretty freaking bad. like a 2-stroke that somebody reversed the gas & oil mix ratio?

After: nary a puff. clean as clean can be.

I took a quick 30 mile ride up the freeway and back, seems to running great. Next step is to do a little tuning on the jetting and timing, but as is seems pretty close for just throwing it together.

Jeff, Larry, Bob, all'a youse guys were spot on.

Also, putting the stock pushrod tubes back in cured the major oil leak. Yay!

The bevel instructions are for the top ring.

Aaaaaaand here's the final product. Well, as "final" as any HD ever is at any point in time.

Quite a bit parred down from when it showed up six weeks ago, compared to the pix at the top of this thread.

The bevel instructions are for the top ring.

Curious why they have the bevel in this case.  I always figured it allowed the ring to rock in one direction and not the other.


Glad to hear you're back on track John.  Heard you go by earlier.  So much for knocking the mosquitos down in the 'hood...
