FileFront Forums - Hlp Freeway Replace wit PCJ600

I got this Buell bike model and trying to replace the Freeway model with it, the zip came with a bikeh.ifp that should change it so the Freeway rides like the PCJ600 but where or what do I do with the bikeh.ifp file??

The Readme just says "I have also included 3 of the bike animation files.. they allow you to replace the faggio/pizzaboy, angel/freeway, and the sanchez with sportbikes and
the riders will have the proper animations.. so check that out..." dosent say what to do with it...!?
