Yesterday, I was out running some back roads having a good time just running a pace on a road I have been over many times. Here is what happened. I came out of a tight left hand curve and turned up the wick to full throttle, but when I let off the throttle, it stuck about 3/4 open! That is something I have never had happen in over 40 years of riding. I had the presence of mind to hit the kill switch and slow down all the time rocking the twist grip back and forth trying to get it unstuck. It finally came loose and I gingerly opened and closed the throttle a few times and it seemed to try to stick at about 1/2 throttle. I was only about a mile from home so I eased it on home. I took the throttle all apart to try to see what had caused it to stick. All I can figure is that the cable that opens the carbs must have jumped out of it's track and got jammed in the plastic throttle housing and would not let it close. By me opening and closing the throttle I must have freed it up and it came loose. The cable that opens the carbs must have gotten too much slack thus allowing it to jam when I attempted to close the throttle as I came out of the turn. This could have been a very bad situation had I been in close quarters or in traffic. I would recommend to all C10 owners to check the tension on your throttle cables from time to time. As for me, I will be adding a extra throttle return spring to the carb linkage to keep more tension on the cable that opens the throttle.
