hi yes it is an exup but an early 1 so ill give it a go and see what happens I did this with 2 different FZR 400s and its easy. I take it you have the earlier FZR400 with the 2 removable frame rails? and no Exup If so you can just pretty much unbolt your engine drop it out and put the 600 unit back in. You can use your existing loom and rad as they are near enough the same as the 600. You will need the 600 exhaust and carbs though, the airboxes are pretty much the same... If you have an Exup version you will maybe need to swap the loom over. I will add some pics of my 4/600 later on (this is the later bike which needs a couple of plates made up to match up the uper engine mounts). But if you have one of the earlier bikes this will not be necessary. Check out my Gallery pics for the FZR400 to 600 Build (not many pics but its in the days before Digital and Mobiles with decent Cameras.... LOL Andy
