I'm curious as to what the weight is of the big bore pistons. Ideally, it would match the stock one, so as to match the crankshaft counterweights and not put undue stress on the connecting rod.
It's definitely a good idea to lower the rev limit on big bored NC250's, hopefully you'll be able to flash the ECU and prevent this from happening.
