Small spot where the piston spat some material.

Mine was so overheated that it lost compression. The section of the bore at the rear of the engine was the worse spot.

Have the bore checked for true. Mine was oblonged, and fatter in the middle (compared to the top & bottom). Once we trued it up, and then removed the scoring, we were just over the max for std piston. Yes, I have an LS660, just like Greg.

Also, a tid-bit of interesting info..... before we trued it up, but after we got the melted aluminum off, we found the bore in the smallest spot was at the factory min (almost too small).

One of the tricks to getting an oversized part within spec is to have it annealed. probably why it was to the minimum.

Mine has only a little spot about the width of a finger. By the intake on the right side.

After I wiped the bore clean I did notice some pitting.
And getting the wrist pin out was a chore.

Anyone know the dif between an '88 cylinder and a 2001?

Don't we run a mild annealing cycle every time we go for a spin? Could we be shrinking our own bores slightly (and irregularly) over time?

We have several reports of this long term "eat the piston" now, two are reported from Savage Greg and Verslagen, two of our most skilled repairmen.

We also have several reports of sudden increased "mysterious" oil consumption during the extended service portion of our bikes. (mine is one of these) that could be a mild case of the same animal.

We may be seeing some variation in our bores based on what gets hot or stays cooler during the anneal cycle -- some possible support exists for this theorum?

If you buy into this theorum, when you do a long term tear down you might want to measure carefully then fresh up your scratch finish with a rigid hone to take out "the tight spots" before putting in some new rings, even if you are still within service bore spec. when measured "overall".

It is a big arsed bore with tight tolerances. Few air cooled steel in aluminum bores are larger than ours.

To anneal steel, you have to heat it up to about 1600°F.
Aluminum melts about 1200°F
600 to 900°F is an ageing cycle (read hardening)

I looked up the part number for the cylinders
'88 ends with a 6
and '01 ends with a 7
I've read before there was a height difference between the early and later models. Anybody else recall anything?

From the OEM parts finder tool the dealers have:
CYLINDER
11210-24B07-0F0 (replaces 11210-24B06)

So, I guess I have a spare jug and piston already.

Minimally for the ageing, and it's not like the longer you bake it the smaller it gets. It's the hotter... And of course the hotter you get it the thinner it will puddle.
