I've had the same issue with my CT110. New spring didn't work for very long at all before it would start acting up again. I ended up having to put a washer between the kickstand and the mount. It's not easy to to get one in there but I was able to do it with a little sweat and blood. In my case I have to smash the washer flatter with a hammer and anvil or the washer is too thick to fit. Lasts about 6 months before the washer wears out and I have to replace it. Don't try squeezing the mount tighter as it throws off the angle and the bolt won't thread.
