Sounds like a awesome idea. Whilst this isn't exactly on topic, are you allowed to run twin engine configuration ? Like 2 max's, or twin leopards ? That would net you the same HP as a NSR250 donk.

Have you though of running butterfly carbs off a leopard ? Would be handy to be able to adj the fuel mixture on the run. They support 32hp each on a 125 revving to 15k, so a pair should accomodate a tweaked NSR.

Anyway, goodluck with it
