The cable ends under the tank are not that hard to access. as daunting as it may sound, you can lift the tank to get to them easier. You just take off the two side panels and remove the seat by two allen bolts on either side, and then the back of the tank has a bolt under the front of the seat. loose the two bolts under those plastic black straps by the forks at the front of the tank and you can lift the tank up enough to access the throttle cables. you can search for a better detailed step by step method of how to remove the tank on these forums, and its really easy. i had to reroute the throttle cables on my bike when I put the highball bars on.
