Lifan Gear selector - damaged?

[Johno]

Hey,

I have been getting false neutrals with 2nd and 4th gear (2nd @ high revs, and 4th doesnt even work anymore).

I have taken off the clutch etc to have a look, nothing out of the ordinary.
I have taken the entire motor apart now to get to the selector to inspect.
Here is a vid, I want to confirm if this is the problem.

The gears have no broken teeth or dogs.. so I think this is the only other thing that can be causing it, let me know.

the 2x selector forks could be possibly be worn, the half moon shaped cutouts, not allowing enough movement up and down.
how much play up/down do they have when sitting in the on the gears?

mate you may aswell keep this all to one thread and a mod will prolly merge it anyways..
are you sure it was not the selector as described in the other thread

Thanks for the tip, will do.

Na I played with everything on the clutch side and got no where...
So I decided to break down the whole motor to have a look, the forks are a little worn and I can see that its been rubbing a fair bit to a point where the actual thing is sharp

then go ahead and order in the new forks, you may aswell now that its apart

Yep, shift forks are stuffed. The gearbox dogs don't engage deep enough and put too much side load on the shift forks, wearing then down.
Shimming the gears for better engagement will prolong the shift fork wear.

Awesome, part is on order. Hopefully see it in a couple of days.

Hopefully the problem will be resolved, last thing I want to do if put it back together again to have to take it back apart.
Hasnt been a bad experience though, lots of small parts and the odd really tight nut/bolt/screw but overall not much to them.

and it gives me a chance to tidy the bike up!

I will post back in a couple of days once I get this part in.

Does anyone need photos/videos of any of the bits before it goes back together?
