fork swap

Hello everyone! A friend of mine told me this is the place to have those in the know help out with builds so here I am humbly asking for advice :). I am putting together a Virgao 750 cafe and have just purchased myself a set of R1 forks for her from a seller who gave up on his 750 project...

alright guys ive seen a lo of talk of gsxr fork swap on the gs series but what years?!??!?! haha is there prefeable years that fit better than others because i would rather least modification but newest era of forks i can get/use ..... maybe a time span? 90-2005 for example? help
