I had to change the clutch cable on my Vespa 50 Special and now it seems not to be working.

I have seen a couple of videos online on how to change the cable and I believe that i have changed it correctly.

Now when I press the clutch it does not go to neutral - I have tried to press it with my fingers directly on the wheel but it does not work.

My question is: Can the clutch brake by just changing the cable or am i doing something wrong here?

To answer my own question
What is very important to understand is that the clutch arm doesn't actually engage the clutch until further in its travel. Push the arm with your finger towards the front of the bike. You'll feel some resistance and then a very definite stop. This is the green arrow area above. This stop point is where the arm makes contact with the clutch and if you were able to push much harder (in the red arrow area) you'd start to disengage the clutch. Many people are making the mistake that the initial travel is where the clutch arm is disengaging the clutch.

I found this video of a guy connecting the clutch.

Try pulling the lever and kicking over the motor, I went through this and found this way gave a good answer if its working or not. Perhaps you haven't adjusted the clutch cable up tight enough?

One other common problem Iíve found with smallframe Clutches/ gearboxes is you may not be able to go from 2nd to neutral if you are stopped in second and squeezing the clutch. Sometimes the handle wont turn to neutral. It is common and just roll the scooter forward a small bit and it will be able to pop into neutral.

I didn't watch the video, but you are correct. I adjust mine by pulling the arm underneath with my fingers and taking out most of the slack but not all. You need some slack, so clutch parts are constantly touching and wear out or burn up parts. Its the same process as a full size motorcycle with a cable. You should have some free play or pull in the handle between the mount and handle. I like to use a quarter or two in my country, I can always take out slack if needed. Looks like you should be using a 10 kronor or so to start with. Its just very important to have some slack!

thanks for the link. About to do the clutch cable and have never worked on classics before. This really helped. It's really just like a shifter on a bicycle.
