Ok so I went to my local shop and asked about my piston and rings and he told me that wiseco does not make a standard size for my 250x that I would have bore it to the next size in total it will be *$270 he also said that my cylinder was fine with just a hone and that something had to be done to the rings so they won't touch when they get hot but I found a standard wiseco and gasket kit for 140 so what should I do remember I only have 400 bucks in it
