im looking to compare and contrast the bare motor and complete motor weights of the ex500, ex250, ex650, gs500, cb250, and the honda 250 and 500 cc liq cooled par twins they sell in europa......i started compiling a list.... because im going to be putting one of them into a dirtbike. if anyone has any information to contribute i would be most apreciative. ill also be compiling basic size measurements and hp ratings at the rear wheel in their "intended" bikes i guess, once i get all the data ill make a chart and post it....
