Slipping Kick Start

[blocky]

The kick start is slipping on my sons tx125. the problem is internal and when it slips you can hear what sounds like gears not engaging.

Is this a common problem and is there a likely cause?

Ideally what i'd like to be able to do is order any replacemement parts before stripping the engine to sort it out. But which parts to order?

I've looked at the parts list on the gasgas uk website but I cant see how it all works. If someone could give me a quick run down of how the parts engage it would be much appreciated. Easy enough to work out once its in bits but i'd like to get the repair over and done with asap.

Thanks

I've done a 321...I don't know if it's the same setup.

If I remember---it's 2 gears that are facing each other and undercut in one direction so they engage in one direction and ratchet in the other, with a spring to push them together.

The ones I replaced were worn, and it was a problem that was not unknown to GG owners.

I remember it being a pretty straightforward job. You should be able to do it if you're relatively handy with the spanners.

You should only need the gears and gasket.

As with any gear that reciprocates (rather than spins), take a real close look at it to see if it's symmetrical. If the gears aren't the same all around the diameter, they will need to be oriented in a specific way that you will need to take note of before you take it apart.

Also take careful note of how the return spring is oriented and how much pre-load is on it.

Also...I'm remembering now...the old gears didn't look bad at all, so I put them back in to see if it was another problem, but they still slipped. So, it didn't take much rear for them to start acting up.

"wear" that is.
