What have you "Offered to the God of Speed" ?

DRDude's torched bike thread brought this to mind.
I re-discovered some things I have "offered" long ago while cleaning
my garage. This was a stroked '81 CB750 crank. Oil starvation was
a problem as the engine was running a wet sump. Back in the day
I called it total loss lubrication. (ie total loss ignition).
It still ran but just a little noisey!! After the engine was modified to
a dry sump & $$$$$, problem went away !!!

So to start this off, a tribute to Burt Munro.



Mine






In the last pic the valves kissed the pistons. The ignition ran off this side
crank.


Let's see what you got....

From a 2003 KTM 640 Adventure. She was running a leeetle lean down in Baja this past Spring. This is what it looked like after about 200 miles. Amazingly, the bike ran okay at over 3,000 rpm - just wouldn't idle!

When I finally clean out my garage, I'll shoot some pics. One of my favorites was my old business card holder. It was one of those custom offset connecting rods, and a nitro melted piston.
I worked for Orient Express and we had a neat collection of stuff. Twisted rods, melted pistons, a cylinder head that was perfect except there huge hole on the #3 spot where a piston went through it.

It was a 883/1200 conversion that didn't have enough piston/cylinder clearance. The sheet that came with the pistons said to use .0015"

Well the machine shop did and it cold seized.

I pulled this out of a early 90's Acura Integra some clown had run into some deep water. i don't know if it was a puddle, lake, or what. Motor had a good knocking noise in it down low. The counter weight on the crank was hitting the wrist pin boss on the underside of the piston pictured.
Needles to say the rod was shortened up just a bit.

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Heh heh, that's a good one.

I don't have any pictures of the motor parts, axles, suspension pieces, bodywork, that were offered up while going way too fast. It was a while ago, and I never owned a camera. Prolly just as well that there's no evidence.

The clutch basket out of my old RM125 that I toasted, I've learned skid plates on woods bikes are alot cheaper than new clutch baskets...



Piston out of my 1974 CB360, oil got on the points and after one of the points cracked the timing was off and opps, hello hole in piston, but she did get me home on just on lung.


Piston out of another CB360 motor I have. Turns out that you can not run a wasted spark igniton set-up on a CB360, stupid hurts...


Head assy out of CB360 motor, on both the top and bottom cam guide there was an oil slot cut in, turns out 1970's lubracations systems don't do to well when you ride the bike at high RPMs all the time, I have a couple of these sitting around...



Rear Vortex alum. sprocket off of my SV650, only 15 out of 45 teeth are still intact...

Ferrari 308

Over revved and dropped a couple valves. Not mine and I didn't do it. 113k miles on the engine. It belongs to a friend's dad. Luckily my friend is a Ferrari mechanic. I think he should put a Cadillac Northstar in there. More power and a better engine.

I don't know if you can blame speed, as the damage was due to over reving at modest speeds, but....

Bent pushrods:


With matching bent valves



OK, the valve doesn't look that bent, but when put in a valve grinder it had a very obvious wobble. The exhaust valves on both sides hit the pistons which survived the mishap.

All Hail KADriver!! Most honorable thread for those of us who covet not thy neighbor, possibly his good lady wife, but most definately all things involving gasoline and spark plugs.

Now I'm off to find a lemon tree to urinate upon.
