Can't seem to get my cables routed to not have any binding. In the picture, it's the top cable that is giving me grief. With that cable off, the throttle is very responsive and snaps back to closed quickly in all handlebar positions. When I put the top cable back on the throttle responds OK on hard left handlebar position but binds badly on hard right. I can't seem to find a good position for that top cable. The cables are new motion pro. Bike is a cb750k7.
