BK i never claimed to be the best or even right, im just sharing my experiences. if you cant handle that then you got some weird issues i dont even understand. if my opinion differs from the norm im still going to give it, thats what this whole internet thing is about.
ada failed for me and others and this topic reminded me of why i didnt replace my ada with another ada. do i need to prove what ive seen to appease the gods? no. i ride ALOT more than most and put hard hours on my parts, thats proof enough for me.
so everyone reading this can take it for what it is, MY experiences. do i really care what you all run? not in the slightest, its your boat! i share what i can so i people can make informed decisions on whats what.

The reason I'm interested is that I had a blown o-ring in Daytona, replaced both with new ones and at least one of those is blown after only 1 day of riding.

I'm all for learning and wasn't aware of this potential issue and will do some checking when I pull the head to change o-rings. I still don't like a half girdle, but that's me based on how a cylinder cracked before.

stanton, if you're going to make a claim, back it up, provide a link. I wouldn't know what to search for right off hand and apparently you did, so help out...

well i guess we can go into the garage, grab an old ada shell and dome, and make a vid showing the dome wiggle inside the head. its easy to see where the head wore out.but its happened to stan and ej...
 
My ADA is 3 seasons old with no issues ,even after I detoed a topend real bad due to my stupidity . I then bored it and changed out the dome and it still runs like a timex .. this is just my experience with this head ... I would buy another ADA if i needed one . just as good as any other full girdled head IMO . I do believe too many guys reuse orings that have been compressed way too long under extreme heat and compression and then expect the head to seal like a new one with old orings !!! but that would ''fail'' under operator error ! also with used orings the domes will not be under the same compression forces to hold em in place and could potentially flop around . but what do I know ... h&ll I ride a couch !!!!!!!!!!

from what ive been told its not the o-rings that make the seal to hold in the compression.

....................... My point was don't reuse old orings unless you have to as a last resort ...... ''' been under extreme heat and MECHANICAL compression as in being"" SQUISHED "" or ''SMASHED to the point of being DEFORMED by head/ jug interference after bolting the head down ................ never mind ........I flunked English
