Predator 500 rebuild....

[timp224]

I put my valve through my piston the other day and im gonna do a rebuild but im not sure if i should bore it out or leave the stock bore. The cylendar didnt get damaged, can anyone tell me what the next size bore is for a predator without re-sleeving it. Also if i go to a 12.5 to 1 compression, can i still run pump gas......

what is the next bore i can do over stock with out re-sleeving?

i dont believe there is a next bore. stock or big bore. sure somebody will correct me if i'm wrong. i sent my stock cylinder to hpd and they sent back a resleeved 558 big bore and piston with gaskets. best $500 dollars you will spend on you predator.
