Trying to replace my throttle tube. Seems like the one they sold me (after looking up my bike in the computer) has a substantially larger diameter - I'm cool with that, would rather be able to go WOT without having to bury my wrist. But it seems there isn't enough slack in the cables. I turned the elbos all the way in, and don't see any adjustment for this on the carb... what can I do to get the cables on there???
