Can't you just get a longer cable to the carbs? I had a bend at the carbs on my throttle cables for the /7 and ended up getting cables for a '86 R80RT. I've never done it, but making cables is supposed to be pretty easy...make your own to get rid of that bend at the carb.
I don't believe you've shown many details of your controls/cable setup.
