[RF Engine Z400 frame]

I have been offered a Z400 bobber frame for a good price.

I know I will need to upgrade brakes etc and add various brackets. But does anybody know whether it will be strong enough to take an RF900 engine? 

Thanks

Hi, Does anyone know if the engine gasket set from a GSXR 750W will fit an RF900R? If not will a different engine gasket set fit?

Thanks James
