[Rome]

two weeks ago i bought an 88 rm 250 the bike is a little beat but ran for a test drive and a few rides after that, the compression was low and i knew it wasnt long for a rebuild. so now im rebuilding the top end, i want to keep it stock just freshen it up. before i order anything i would like to know the bore and stroke and things like that. also any feedback on parts or places/sites that people have purchased or purchased from would be great
