1 for the 2stroke lads

[wtf?]

anyone know if a Honda NSR 250 MC-18 engine will go straight in to a MC-21 without any arseache?
i know they all have the MC-16E designation but im scared that shit like powervale pulleys maybe different or that the carbs rubbers wont mate on the reed blocks and other shit like that.
anyone know for sure?
thanks
