doubt you will be able to drop the front sproket. That mod is normally for the 996 etc which has a 15 tooth front sprocket and everyone fits the 748 14 tooth front sprocket to get quicker acceleration.
You should already have the 14 tooth front sprocket on a 748 and you can not go any lower.
Better mod for you would be 2 or 3 teeth up on the rear sprocket. May knock 10mph off top end but will turn the bike in to a fast accelerating wheelie machine
