I'm not real sure what is going on but I changed my bars and had the carbs out (because I thought I was going tubo) reinstalled the carbs and put the cable housing back together, and now the throttle sticks. Its not all the time and usualy between 75% and wot. I have checked my cables 7 or 8 times. I cant see any kinks or tight spots. I lubed them up and they got a little better. I have tried adjusting them but nothing.
