Honda CR250R. 2000 What the biggest size piston can go in a CR250 year 2000?
Question edited for clarity (again :) Always include full 'year make model' and in that order, as first 3 words please. That is the info that needs to leap off the homepage.
Question moved to model category (again :) There are over 10,000 to choose from.
The company that does the rebore will take care of all that. They are the experts, leave it to them. They will take it, measure it, bore it, hone it, supply the piston and rings
Another alternative is that they can bore it out and insert a sleeve and put you back to the stock size.
Before doing all this, have you checked for broken piston rings?

Was the bike sitting for a while? If so was there fuel left in the carburetor? It kind of sounds like your carb could use a good cleaning.
To do this basically unscrew the top cover from the carb and remove, the slide should come out with it. Next loosen the clamp that holds the carb in the rubber boot by the reed valves. Remove the carb. Next remove the bowl by loosening and removing the screws on the bottom of the carb, these should be Philips head screws. Gently remove the float pivot pin with a pair of needle nose pliers. Remove the needle valve, and seat. Using a spray carburetor cleaner and a paper clip, clean as much of the tarnish out of the carb as possible, including the jets. If you have access to compressed air, blow out the jets and bowl. Reassemble in the opposite manner of disassembly. Your bike should fire up, if not repost and we'll try to come up with a different solution.
Good luck.
