1971 Bonneville T120 Kickstart Stop?

Hi I wonder if you guys can help. The kickstart on my bike goes right round from about 10.30 to past 3.00 oclock it almost broke my knee when I first tried it! Should there be a stop fitted and if so where do try to find it.
Thanks in advance. Graham.

 

The resting position is as you say but its when it goes past the bottom and still going forward and back up that it hurts the knee. I wondered if there should be a stop at the bottom??
Thanks Graham

 

Thought I would give a little more information. When I start the bike I used to jump a little, lock my knee and use my weight to drive down and start the bike. It always started first kick but hurts the knee when it goes past the bottom and back up. If I just sit on the seat and use my leg its no problem but can take a few more kicks to get it started.
So just wondered if there should be a stop at the bottom. Graham

 

Ok thanks will give that a try. Graham.
