So I've been thinking about doing this for a few years now.
I know it's not as economical as buying a replacement engine but then . . . it woldn't be Lily.
Anyway . . . I was calculating the projected gains from one of the manufacturers and low and behold it wouldn't be a 750 . . . it comes out to 757cc.
I got Mase's 757 sticker already so I'm thinking . . . heck maybe it's time to make the change!
I've also been told that a 750 "up-converted" 620 with the stock 620 cams will have markedly more cojones than a stock 750.
*poke*
Do it.
Paging Teddy... He did this recently. It sure sounds better, but I can't speak for the ride.
Ohhhh . . . if she sounded better . . .
I love my Italian mistress! ;D
<enters the voice of dissension>
it is
really expensive
and
the power gain isn't worth the money (i know, already covered)
but
you would be taking a rock solid, dependable motor, one of the most dependable Ducati has made IMNSHO
and
make the beast with two backsing it up
Not saying that
you as in
chuckles would make the beast with two backs it up
but modding a motor to that degree
is asking for trouble
as to this

a fuelie 620 with a converted box, cans, and a tuned PCIII
already has more poop than a stock 750
but
again
this is just my opinion
I fully support any and all irrational modding
seriously, look at what I ride
I'm with mother on this one. Modding a motor usually makes it less reliable. Sourcing a used 800 motor and adding a PC3, etc. would probably get you a more reliable, more powerful motor at a lower cost, especially if you sell the original motor. Your girl with a new heart is still your girl, just twist the throttle and you'll know.

Cheap mod... strap a tambourine to the side... instant dry clutch sound. Gain of about 50 in vHP... (visual Horse Power.)
Bwaaa haaaa haaaa!
But you complain she's too loud all ready! ;)
this is my take on engine conversions.....
If your looking to keep the bike FOREVER go ahead and do the conversion. I had a 883 harley with a 1200 conversion kit on it. Thing was faster than any stock 1200, ran like a top and never had any problems. But.....
Resale value is not good. You gotta think of two things.
1. You will never get the money back out of it when you go to sell it for the conversion. People dont care that you spent X amount of money on the conversion, your title says 620 on it and thats what they will pay you for it.
2. People dont want a bike that has been converted. They feel as if its been "make the beast with two backsed" with and even if you can give them receipts showing that the conversion was done professionally at the dealership it dont matter, they still dont want a bike that has been screwed with.
So....do it and youll like it chuck if you plan on keeping the bike forever. Dont do it if you plan on selling it someday.

This is the same that I found true with off road bikes... people do not like bored over conversions, cause they are afraid of what it means to reliability and time till next total overhaul. Once you touch the engine with an internal mod... people start to freak. I had some Banshees where I went in and had them bored over, the crank welded, and the airboxes opened up... and when I sold them... "I would prefer a bike with a stock motor.. that way I know what's been done to it...and where to get parts.. repair work.."

+1. My ATC 250R is worth what it is because it's one of few that hasn't been "mandatorily" bored over. Runs like a champ, too, never a problem, and it's three years older than I am.
Not that I don't hold modifications to a certain merit. I always believe in making my vehicles my own. Then again, unlike some indecisive people, I always do plenty of research before I pick something up, know exactly what I'm getting and getting into, and intend to keep it for a long time.
