Lean map & MR9 caused some damage $$

[GPW]

Just as an update:

KWS Head and Big Cams
13.5:1 JE 1441 Piston Kit Gen I (Buckets)
Heavier Valve Springs
Studs
Gaskets
Bearings
Oil Mods

No sense in just fixing the old stuff!

Terra (mother of my son guys) does her best to help out...sometimes I just get distracted if you know what I mean.

I hope you guys like the photographic evidence. I also work for a Law Firm diagnosing product failures or abuse. Do that on top of everything else (10) jobs one guy. Enjoy GPW

The owner handles insurance stuff....SWEET he wanted documentation.

Won't discuss the details of the map...it was not tuned by HPC. Had a base map...and it was reportedly checked on a dyno and the AFR was 14.1 after tune....reportedly.

[mattstang]

thats cool. i was wondering if it was canned or dyno or stock. i guess since the afr was checked it was on a dyno. i like the pics and your a lucky man to be able to have your wife at work with you.

Sounds like it had a PC3 or PCV on it with the Busa base map from DynoJet. Is this correct, or was it running with the stock O2 sensor?

It had a PCIII with a tune...thats all

Wow, looks like some pretty nasty damage. Im sure you will have it making big power in no time !

It will be a full-time drag bike, never to see the street again. It should run very well... owner ran 9.3's stock wheel base 225lbs before....we will see.

Cool pix... Terra is distracting but not as much as Nitro...if you know what I mean.

She said you look at her funny

Great pics and updates !! Thanks

I too like figuring out the forensics. Wanna hear my take? I may be 180° wrong, but at, 14:1, it seems richer than 14:7.

You say the head gasket was aftermarket thin? Stock studs being the guess? Did we grow and lift with steam?

Water contamination sure did not melt any piston at TDC or say peak compression where a knock would hammer the electrode right at that circle at the piston. Each one is clean as can be.

The plugs still have their side electrodes and those would melt being a thin glowing wire to flick off or more arc the little circle in the piston dome.

So, we now look at the white crystal vaporization out the ports and the peppering in the cylinder chamber/head area.

Note the bluing at the valve cuts on the piston. Like you left the pan on the stove and the heat rainbows the cutouts via the color offset.

Now, what if the MR9 was water/H20 mixed with a low gas tank with the condensation at the top of the tank? Sloshes upon transport; drops down to the deep bottom, being water is heavier than gas/oil.

My take is H20 related somehow with the crystallization rampant at every cylinder. No det damage but for sure, det inducted on the mild/no welding or melting of parts like hole in the pistons or even some sort of blast of the piston dome material removal.

I would think one bearing #1 has lost tolerance and the oil w/tolerance cannot hold the piston in a gliding type stock/tight movement.
I would step on my member and continue to point out that the slop of #4 hanging up is the snowballing/galling of contamination inside the cap and rod that binds the rod and the friction makes it hang there.

So, my conclusion would be water contamination related as to the cause of the det and because the steam more washed the flame of say pure oxygen being more powerful a melting of metal than gasoline, if we were to match which chemical can cause the most damage is pure oxygen out of a welding tank kind of white heat source.

But I would assume the steam was more a cleaning agent rather than a burn down agent, being, we can see a clean head, clean valves, clean piston domes; washed clean of black carbon buildup.

And a good det engine would have a "C" kind of curve to the connecting rods, being no place to go but bend and smash down onto the oil film and squash that right out of the way so there is metal to metal contact to destroy the lube properties for one, and hammer the soft layer into a larger tolerance where the oil has an easier time to be pushed out of the way, and the loss of the film/pressure needing triple the flow to compensate for the extra clearance.

I'm sticking with my story unless you can show me there was a lean condition. I mean, 'lean is mean" and if that makes some HP to lift the head off and grow the engine studs, that is one hot map I'd reuse.

I'll leave that up to use is goo wooz to ponder that failure...

I'm just an amateur with all these mystery mods go fast sheet is pond deer the possibilities.

Hmmmmm. Interesting... Good post, makes ya think !!

[GPW]

It took a ton of heat to blue this piston...just a rookie

[GPW]

Tomorrow I will post what a stock piston looks like particularly the centers..
