1976 125 Enduro Kickstart Ratchet
I hope your all keeping busy.
Since I got the bike it had a problem with the kick start. The ratchet would simply slip. The lever could be pushed, but the ratchet teeth would not engage.
Me being clever, I thought I could just open it up and stretch the spring forcing the two ratcheting parts closer together. Well, that and my stupidity was the beginning of my problems which due to this enforced holiday, I have now had the time to overcome.
To cut a long story short, I stretched the spring making it about another 15cms longer. This enabled me to be able to kick the bike over, and with a dribble of fuel in the cylinder it fired up. Wahay! It ran! For a very short while. No problem. I'll give it a few more kicks and see if the carb is allowing fuel through, since I now know I have a spark, and at the right time.
I went to kick it again, and the kickstart has reverted back to how it was. Slipping ratchet.
So now for the questions...
- The manual shows the spring with the tighter wound coils toward the left crankcase half. When I took it apart, and looking at the bent ends of the spring, it should fit the other way to how the manual depicts, with the tighter wound coils toward the gear. Does anyone know the correct fitment? It really looks like it will not work if fitted the way the manual depicts.
- How worn does the ratchet gear need to be before it is described as worn? There is some wear, but I didn't deem it as excessive.
- Does anyone have a picture of a good kickstart ratchet for this bike so I can compare to see how worn mine is?
- There is an amount of endfloat in the kickstart shaft. How much is too much? Should there be shims to alleviate this? The bronze bushes are in place and do not look worn.
- I saw a picture of a spring on Ebay. It looks really short. Is there meant to be a washer at the circlip on the shaft to hold the spring closer to the gear?
I will try to add some pictures to make my words mean something. The picture of my parts shows the spring the wrong way round to how it came out. I fitted it with the tight coils the other way as it just looked wrong otherwise. If you can zoom into the teeth on my ratchet, please let me know if that wear is excessive. For my next trick, I am going to file the teeth to get a tighter edge on them unless someone tells me otherwise.
I tried winding the shaft round by holding it at the end of the kick, loosening the retaining bolt underneath the crankcase, then winding the shaft on and tightening the bolt again. I did this three times in all. It just means the lever returns quicker, it does not load the ratchet.
Hopefully someone can help.
