Different rearsets is the only way unfortunately. One that offer a pivot point around the old gearchange lever pivot Adjustable Pegs Rear Sets for Honda CBR 1000 RR 2004 2005 2006 2007 BLACK | eBay I have these on my '07, and they work very well...I've always used race pattern on all my bikes where I can.
on a lot bikes you can just turn the knuckle that attatches to the gear input shaft through 90 deg,unfortunatley with the 04-7's you cant due to the clutch slave cylinder,so as above,different rearsets that pivot the gear selecter rod on the opposite side of where it is now. you can get some cheapish ones for under 100 quid
