Looong wheelies,
Makes oil spew from the crankcase breather, all over the engine and most importantly the rear tire.
Nice, real nice Ducati.
Is there a DP carbon fiber PCV that I can fit to allow me to continue to wheelie without the Spy Hunter-esque oil slick result?

Take the breather hose off the airbox (cap off the airbox if you have one) and add a coupling and more hose long enough to reach to the steering head area, top off breather hose with a small K&N breather filter and that will solve your problem.
I haven't see a carbon breather valve, but they do make them in aluminum. Aloha Alex

I put the stacks on, so no airbox.
So just extend the tube up as high as possible?, that would be a good trick if it spews on my face the next long wheelie I do.
That sounded kinda gay.
Is there a possibility of damaging the engine with long wheelies?
I know this has been discussed before but we never had anyone with some real "proof" that the angle of a wheelie really does starve the engine of oil....
I guess if the oil is spewing out the breather than it is?
Or if enough spews out there is.....

yes it can hurt the motor,but you'll never know how much unless you take it apart. if the oil pump pick up gets no oil thats not good on any bike. from my understanding it hurts con rod bearing the most

The old CBR900rr had to have its oil level overfilled by one quart to eliminate oil starvation during long wheelies. Ultimately, some stunters (Starboyz) moved the pickup to the rear of the case to completely eliminate that issue.
Jason Britton discovered this problem on the Hyper when he was asked to wheelie over a very long bridge for a photo shoot. The Hyper he used had an airbox which caused the motor to ingest the oil and damage the connecting rod and head I believe due to hydrolocking.
You are probably fortunate to have the stacks vs. the airbox for this reason. I have the airbox (for now) and have done wheelies up to and around 3/4 of a mile or so, but by then I get bored and start rocking the bike back to see how far I can go or I just set it down and consider myself fortunate that a cop didn't crest the horizon.
I have considered Alex's reply before when I do get stacks. I'll probably plumb the filter up to the steering head, just inside the frame.

 That's not mist is it?
So I don't get it. Was Ducati supposed to design the engine for people who want to do long wheeleis?  Is that the common way motard riding is done? What does using your bike for stunt riding and then having to do work arounds or major repairs have to do with Ducati?

Yes, that is a common way motard riding is done, its a common way all motorcycle riding is done.
Yes wheelies are a common way ALL motorcycle riding is done, off road especially, which is what motard is based off of, with the exception of one manufacturer who has a massive following, Harley Davidson.
Although there are some that dont wheelie everyone loves a nice clean balanced wheelie.
Not in traffic, of course.
And there may be some that dont wheelie, but Ducati designed a bike that will be damaged if wheelie at distance, a bike based off of motard.
I suppose that since the bike was designed to carve up corners is why the suspension is some of the BEST in the industry?

Suspension isn't that good actually. Stock 749 suspension was way better quality and handling wise than the suspension on my 1100S. It is weird why ducati didn't use a dry sump on this bike so that it would be better for handling longer wheelies.
