Shrapnel Italia by Ed Milich
Guzzis are among the most overbuilt, understressed motorcycles on the planet. They are still machines, though...and machines break. Below are the results of abuse, neglect, user error, and the limits of modern engineering. Each destroyed part has a story to tell and a lesson to teach. Enjoy the carnage.

Cam timing gear from my old V700 that died at 4000 RPM going down a city street. Possibly from a porosity in the casting.

Torched connecting rod big ends and crank- ran it out of oil.

Broken rear brake disc- Went to the pub one sunday lunch, got a bit of vibration, then when I used the brakes they juddered rather badly.
Got to the pub to discover this...

Why I hate aluminum timing gears (galled aluminum timing gear teeth). The gear on the far right spent only 10k miles in a Spada...

Sudden failure of a

*Credit where credit is due dept: Chris Bell actually blew this up, not Mike Haven, as previously reported. Good job Chris. :-)

This is the result of a big knock on the right hand head and the forces have found the weakest point witch apparently is the clutch house.
Apparently!

Uffe Juul Motorcycles, Denmark
From the 'who-the-hell-knows' category. Perhaps a victim of L.A. traffic? May prove that the rear drive housing is truly not bullet-proof.

"Why plastic bearing cages are a bad idea in a transmission bearing" The bearing on the right had a cage failure and the resulting debris ripped up my tranny input seal.

Failure mode of a Voltage regulator- It allowed the charging system to operate at up to 16 volts.

This is the crank from a friends' LM1000 that broke during riding. 'The engine started running roughly...' Possibly caused by a bad grinding job?

This is the front half of the crank pulley on a 74 Eldorado. Probably the result of overtensioning the belt.

This is what's left of the front main bearing journal of my '96 Sport 1100 after only 56,000 miles.  No apparent reason other than because it could. I suspect the nitriding oven might have been running a little cold that day, as the step height is about 0.006 inch and the ID of the bearing is very chewed up, but still within tolerance so the crankshaft is the only thing that wore out. All the other bearings in the whole engine are still OK.

I had the tranny warranty work done to my 00 V11 sport.  Replace a couple of pieces to prevent a transmission lockup.  I had all the springs replaced while they were in there.  When I got the bike back the neutral indicator light would come on randomly.  Turns out a clip had broken that holds a shifter cam onto a pressed fit shaft on the cover.  While I was riding out in western MA on Tuesday I noticed transmission oil leaking from the shaft, so I kept an eye on it and headed home, stopping 5-6 times to check it. On the Mass Pike at around 75 MPH  the shaft fell out of the case onto the road.  I happened to look in the mirror and see smoke billowing out the back.  I knew I blew a seal or something and the rear tire would be soaked with oil.  I slowly pulled into the breakdown lane.  I used the front brake to slow down to about 50 and downshifted, not realizing the shifter cam had fallen into the tranny.  BOOM and a nice controlled rear wheel lockup for about 150 ft...

This winter, I wanted to have a twinspark modification. Didnít have much money, so I gave the heads to "someone who could do the job for little money"....and I knew...One sparkplug is to deep, the other one not deep enough, one sparkplug is slanting, oil passage at the pushrods leak and put silicon in it...Also, he drilled one hole at the wrong location, after that, he  "fixed it" by screwing in a bolt or something...as can be seen in picture 17 and 2.

I foolishly lent my 750 S3 to someone to do this year's Giro d'Italia
in Sicily - on the third day he went straight on and too quick at a bend,
over an embankment, and down a grassy slope, and the bike flipped over a
couple of times. Seat broken in 3 places, rear mudguard ripped completely off
(amongst other damge to cylinder heads, tank etc) - if anyone comes across
an original S3 speedo with 90.000km on it while wandering through long grass
somewhere in Sicily, it's mine!! Testimony to the Guzzis strength though, forks were fine, Borranis were fine, frame is fine!!

Previous owner of my SP1000 mounted a LM swingarm with the original
driveshaft (20mm too short). I drove about 4000 miles with this shaft till
it broke. U-joint failed too, spline is still usable but the bearings
died.

Ujoint from '72 Eldorado, Previous Owner said he "hadn't noticed" any vibration in the drive.
