Loooks like you had a wrist pin sieze up and caused the side loading on the skirt until it broke. Did the wrist pin go in hard?

 

It would be interesting to check your barrels for roundness. I noticed in the first picture looking down the cylinder that it is discolored on the right top and then on the top area on the other side near the stud bore there seems to be a heavy worn area...looks out of round near the top of that barrel where you need good seal...and I noticed that the pistons are very discolored below the second ring...shouldn't be like that if the rings are sealing well...did you have a blow-by issue??...you're really lucky it didn't hand grenade on you and toast the whole motor...

I can't believe this.... I don't think I have knowingly broken any mirrors but maybe one of my X's put some voodoo on me!

Went out in the garage tonight to tinker with the money pit and pulled up on one of the cylinders (just happend to be the rear one) and it slid off really easy.

Set the jug on the bench and this is what I saw:

Just hit the "Next" button and scroll through the gallery to see more sickening photo's unfold...

(Is there a sticky on VTF that tells you how to inset thumbnails and photos? )

I'm in the process of stripping it to the bare cases to ship off to KOC for 117" re-birth.

Could this the result of the short-skirt syndrome Randy was talking about?

I babied this motor prior to this happening as I didn't want anything to happen after all the %#%@$!% money I've out into her. Then one day going about 85mph home from work I started hearing weird noises coming from the motor and got too spooked to ride it anymore.

S&S 4 5/8 crank will be up for sale soon if anyones interested...


In the words of the famous Paul Harvey - "And now you know the rest of the story"...

Hyperformance 117 coming in the future.

 

No problems when I put her together, the pin just slid right in.

Before I removed the pin tonight, both pistons rocked back & forth very smoothly. Only after I removed the rings & clips and tried to push the pin out did I notice it wouldn't budge.

Both pins were the same way.

 

At this point I question everything about this motor. I'm going to send the cases out to KOC for inspection to see if the initial machine work that was done on them by the original clown-azz is even correct!

They may be contributing to the problem as well. At this point, nothing will surpise me!

Where's my stimulus check!!!!!

 

Few notes from an old fart...

The scratch marks in the pistons are from the crappy bore job SnS does.. I've had 4 sets of cylinders from them and their cylinders are too soft requiring a gentle brake in and they don't plateau hone the cylinder very well to start... Heck I ordered a set of 116 cylinders through an indy and one wasn't even finished to size.. Nice thing about the second was that it had a rear piston in it..

The problem with your piston is not uncommon.. I have a wiseco that has a crack on the cornered but no pieces lost. It a problem with the forging process where the aluminum may not have been hot enough.. (according to panman)

Your motor is running a little hot based on the underside of the piston or you are using a funky erl..

Did the bushing spin or did they forget to drill it?? You should be able to get away with the pin sticking in the piston or the rod but not both..

"Where's my stimulus check!!!!!"

I got a cattle prod around here somewhere.. Bruce

"Did the bushing spin or did they forget to drill it?? You should be able to get away with the pin sticking in the piston or the rod but not both.."

BTW, didn't cause the crack unless already weak.. Bruce

 

These were the brand-spanken new cylinders, pistons & rings that S&S sent me to replace the original set issued with the 124" Hot Kit after one of those cylinders cracked...

The bushing spun in the connecting rod as I can see the hole that's in the bushing and it wasn't like that when I assembled the motor back together.

I will continue tear-down tonight and go through another box of zip-loc baggies marking everything so when the time comes I'll know where it all went.

No telling where the pieces of the piston went or what other damage was caused.

I might end up looking for some new cases if these are jacked-up too badly!

I am pretty meticulous when working on my bike, I don't like learning too many expensive lesson.

I would of thought with a company like S&S you wouldn't have to machine or modify any of their products but be able to run them straight out of the box.

My wife appreciates so much the fact that the Corp honed my janitorial skills to such a fine edge, she insist that I maintain them every two weeks cleaning the head!

So here I am again, more than a couple $K going into the money pit. I'm not in a hurry but will definitely miss out on another beautiful Florida summer.

Will take plenty of pics and try to figure out how to post Thumbnails & why I have to use another site to load pictures to this site?

 

I'm sure the folks here got you covered as far as the mechanical issues with your bike. As far as the "voodoo" issue that you raised, you better make sure that you got that covered just to make sure that nothing weird happens again. Be sure to not leave toenail clippings around, because if the X's get those, you got real trouble.

 

I would contact S&S, send it all back to them. Let them replace, they may stand behind it, have surprised me in the past. Then sell the stuff, and start over with Randy and R&R. I assume you have H-D cases, so R&R crank/heads, Axtell cylinders etc etc. Best of Luck.

 

i've been down this path of bad luck. sometimes yer the hammer, sometimes yer the nail. i don't like the idea of that long stroke, but sure is a lot of people out there running them.

 

Wow interesting pics!!!!!So no more 124 huh??? You down grading to the 117??

 

No more 124...

I've been dealing with this problem child for too many years and missing out on all this Florida sunshine!

Going to have to change my VTF name when the time comes, hopefully being a paying member that won't be a problem changing out 2 digits... LOL!

My stock HD cases will be reused if they are any good (Will have to get KOC to inspect them).

KOC has sent me a rough list of what will be needed to transition over to a 117" so I have a starting point.

But this one will be completely assembled by KOC - eliminating any possibility of error...

I'll be content working on the chassis and all the rest.

SMART MOVE!!! KOC WILL TAKE OVER YOUR NIGHTMARE AND TURN IT INTO A DREAM!!! THEY WILL BUILD YOU A MEAN, RELIABLE BEAST!!! :woohoo:
Trust the experts to do you right and your trust will be rewarded...

 

Man,

Checking out the end of my S&S crank, where it fits in the cam plate. That sucker is severely grooved but only on one side? And the bushing in the cam plate feels odd too. Hard to describe...

I'll take some pics tomorrow afternoon of the crank. Other than something being bent, how could only 1 side of the crank surface be worn so bad?

But nothing will surprise me with this junker...

Bad pistons, bad cylinders, bad crank...

I just hope the cases are still good.

More to follow!

 

damn the bad luck..... from what i have read most of s&s cranks have to be reworked..

 

Yeah, as long as you keep writing checks anything can be fixed!!!!The King will do you right!!!!Good luck & keep us posted on how you & the King make out on your new project!!!

 

Does this motor have the piston oil squirters?The stroke is not your problem.

 

Yep,

Squirters are there. Something else I noticed when I pulled the Feuling Superpump & cam plate out.

The O-ring for the oil pump laying in the bottom of the crankcase in two pieces. Don't know if it fell out when I pulled the pump out of if it was there the whole time.

But it was clearly in two distinct pieces.

Maybe it was cut in two when the pump was pushed into the hole or something?

Guess it's a moot point now, KoC will square it away I'm quite certain.

If these cases are shot, there's no sense in going with a 117" then...

This a sickening waste of money and time...

What a lesson learned.
