FX-1 Fx-1 compression question.

Hmmm, Thats kind of a bummer, the one piston looks mint. the other one not so much, Are they std or over bore? You should be ok with just a hone and new pistons, Shouldnt need to over bore, just a good honing. And yea my head is the same shape as yours, just painted red (originally anodized silver). Im also having a hard time finding info on greater heads.

Yea, but I was kind of expecting stuff like this would show up. I'm really worried about whatever it was that caused the damage to the domes.
I'm not sure as I don't have the tool to measure, but I get the feeling they're stock bore.

Oh does it look identical besides color?
And do you happen to know where you can buy great replacement domes, i've seen other brands but I'm not sure they'll work.

I do believe the ADA domes will work in these heads, I havent opened mine up to check the dome size yet, Yea mine looks the same just without the 4 outer bolts(cylinder to case bolts). And for the pistons, they should be marked STD for standard bore, then 1.00 2.00 and so on for over bore (in mm).
 
I was looking at those, they seemed pretty close.
Oh okay. Interesting that another fx1 has the same setup considering how few and far between these heads seem to be.
I just checked and these are the only markings. The top has F an arrow pointing left and 25, on the inside there is what looks like a 3 then an upside down T then the letters ART. On the opposite side of the inner walls there is a 61x00.
Do stock pistons have std on them?

I do believe so, the stock pistons should read std referring to standard bore (original, not overbore) the 25 leads me to believe it is .25mm over bore. Not 100% tho. But my pistons read 1.00 which is 1mm over. Ill throw up a pic of what my head looks like for ya.
