While rummaging the classifieds I came across an airhead that had roughly 30K miles (odometer broke). They offered the following maintenance as being recently done:
Valves ground; Cylinders honed; New piston rings and wrist pins installed.
I would have thought this type of work would not be needed on such a low mileage engine. Is it because it sat around and did not get used, or maybe was simply abused, as in improperly maintained? One other possibility is that the mileage is far greater than what they claim it to be.

I agree. If well maintained it shouldn't have needed any of those things until double the stated mileage.
-
What year Airhead? From 1981 onward, the cylinders are nikasil plated and cannot be honed. If the seller did hone the later cylinders, take a pass on this bike as the cylinders are toast... nothing but problems for any future owner.

Good point Montmil. It was listed as a 1980 bike.
The reason I brought this bike up was I had someone who appeared to have minimal knowledge looking over my bike. He wouldn't be the first person to compare miles on a bike and state that a particular one has 10k less than the other - suggesting its a better find. I typically don't try to influence them to consider other factors.
Turning off topic here. The same individual had commented on the paint being so good. I would say it must have led a sheltered life, because I think it is that good too. However, the tank is way too good too be original. In addition the tank roundels are also brand new looking. When I compare the roundel to the rear trunk, which is yellowed, I kinda wish that was the same condition for them as well.
I watch a lot of those antique, restoration, collector type shows, and they're always bringing up the value of a item being worth more in the untouched state. I suppose it depends on the category of item. I tend too hold the same opinion on most things as well. ;)

Nice B-model Mustang on landing roll out!
1980 R65 cylinders can be honed.

1/2 hour ride cost $2200

Filling in one week as second mechanic for a 100 Hour Inspection, my ride in a D-model Mustang (to warm the oil before change out) was free!
Without the weight of WWII vintage radios, armor plate and those sweet .50 cals, acceleration on take off is breath taking.
These aircraft are truly rich boys toys.

That would be an honor, I'd hand wash shop rags for a chance.
I didn't get up close that day, but I did find a site that has more information on it.
Apparently "Betty Jane" is one of a kind in that it has dual controls.

I assume these folks never utilize the blower, thereby operating it conservatively so as to guard against the extreme costs and potential self-destruction associated with using it. During one museum visit in the long past I recall the guide saying they wired the handle inoperative. I don't remember the aircraft, it was likely a Bomber.
