that is such a small change that you wont have to do anything different. but you do need to figure out why the top end went the first time or you will just be redoing it again soon. a leakdown test is a must once you get it together.
it is boring, no e.
and all you have to do it get a piston kit (piston, rings, wrist pin bearing c-clips) and top end gasket kit. but first make sure that you have the right size overbore piston kit. dont want to get a .020" and need a .030" or .040"

what is the biggest bore that i can go without really having to make significant changes to the rest of the motor
what do you guys think about the vitos 240 big bore kit. i like how it comes complete with the head and everything.
I would stay away from that brand. It seems like there putting out junk now. You should do a thread to get other peoples opinion on Vito's big bore kit.

But porting the stock cylinder will get you more power than a big bore... unless you port the big bore

yeah dude the la sleeve is much better than vitos power wise and just about every other way you can think of.
It sounds like you wanted to bore your cylinder to get more power not to fix a problem. if you want more power from the cylinder you have send it to kenoconnorracing.com or flotech. someone like that and have it ported and the head milled with a new bore and piston. it is a few hundred cheaper than a big bore and it makes good power. but you will need some good exhaust and some jetting to make it run well.
