broken piston

like i said I have a good running bike and this motor I just want to build for power I dont have a shoestring budget but there is a budget and a 560 jug wont fit the 160 sleeve kit will fit so what I am asking is, is the sleeve kit which says that it will bore it out to 240 is that worth the money or would you just steer clear of it all together and if I go that large what else will I have to do to the bike thanks again for all your help

you gotta remember the machining costs of getting that sleeve installed. and as ive said before a stroked and ported stock jug will eat a unported BBK
