Would anyone know where i can get a set of oil hoses made up with the correct fixing for a gsxr or would i have to use the ones of the original hoses and adapt them?

you could try pirtek, theyre normally pretty good... might have to adapt what you have.

Locost, quick, simply solution is what I utilise... I simply remove the existing crimps (hacksaw, angle grinder - I have no trained ferrets), revealing beautifully formed solid tube ends that take standard 1/2" oil hose and jubilee's.
