Kickstart not (always) engaging.

[psychedelicropcircle]

I am sorting out a club mates scooter for Ireland. The kickstart wasn't engaging so I adjusted on the 3 bolts all the way in 1 direction. This seemed to sort it out only for it to fail after it was put back together. We got it engaging but I'm not confident it'll always eventually sort itself out. It's a SX 200 case with a non GP chain case. The gear didn't look worn (2yr old Indian GP box)

Any suggestions fellow roticas?

Could be a couple of things. Hows the teeth on th kickstart piston. Is the spring behind the piston ok. Whats the shim/end plate clearence like.

put a 5 pence piece under the spring

put a 5 pence piece under the spring

That's a good idea, Eden but living a bit nearer Yorkshire I would use an old flat washer,

Here's the gear next to a good in. Might look a bit worn on the edge.

Thoughts?

the only problem area I've had over the years is the actual K/S piston- it really needs to be 100% otherwise "missing" can occur. Change the piston and spring.

Is the piston moving freely in the shaft?

Is the guide pin catching in its slot?

Well the 5p trick didn't work for me, it pushed the circlip out. He's a plumber time to put his hand in the pocket

I had issued similar to this a little while back. It turned out to be a worn drive sprocket that was slipping around the drive sleeve sliding dog. I tried two new kickstart pistons and springs before I found the problem. It's worth looking at that as a cause.
