I am completely rebuilding my 1995 CR250R and it needs a sleeve anyways so I was thinking of getting it big bored.I would like a good bit of low end but I also want a good midrange/topend hit.My question is that how much top end does a big bore take?Also is it worth it since if I completed my project and it was big bored and it blew up wouldent I need another sleeve then instead of a bore and hone?Thanks for any help. :)
