Welcome to the site my irish friend...:D :D There are many big bores available.....most common on this webpage would be a 416 probably. Try doing a search on 416 kits and decking the cylinder,,it might answer your questions..

Well I have a 99 400ex with an IMS 440 big bore in there and I love it. The why I take it you have your crank strocked so if you do the 440 big bore it will more than likely be in the neighborehood of a 470cc then. this will cause the motor not to rev a high, but my self I like the bottom end of it. thats what I would go with. But the 416 big bore will still let the motor rev conciterably than the 440. ether one of those would be a perfect choice. the choice is yours dude.
