I seem to remember that you will need to machine the crankcases to accept the larger barrel sleeve. It might not be quite as simple as just fitting a barrel and piston plus cam. There's also the question of fitting larger valves and machining to fit.

As for servicing, then I'd guess it's no more or less than normal servicing except you'd have to re-check valve clearances and the basics after the 1st few hundred kilometers.

Also, as you alluded to, there would be an increased fueling requirement which would mean something like a Power Commander and some dyno runs to match it all together with a larger air supply.

Tiz only a guess, but it has been done....Kev's your man, ask him directly if you have subscribed to the forum.
