Hi,

You are right about the lack of a mechanical drawings for the forks.
There isn't even information about which type of oil to use, and how much
oil is needed.
The problem is my scooter is an old model, and the dealer doesn't even have
a new complete shock absorber.
So i either try to rebuild it somehow, or i can toss the entire scooter to the bin.

I think i'll try your method, to open it from the bottom bolt.

Thank you for the detailed explanation.  :)

With my shock absorber there isn't a plastic cap sealed into the stanchion.
There is that black cap which can easily be remove, and under there is what looks like
a metal cap but it's not a cap which unscrew.

Not sure we have the same exactly setup.
I don't want to open that bottom bolt until i'm 100% this is the right way with my shock absorber.

Why SYM don't use standard shock absorbers?

Hi,

Thank you for the quick answer.
In the videos i watched on youtube, you can see they are also open that bottom hex bolt, but
they fill the oil from the top, where there supposed to be the cap that you unscrew.

I found this instructions from another scooter manual, and it looks like the same shock absorber design.

Seems like you need to push that top cap inside, and then remove a circlip to be able to take the cap out.
Problem is, it's not moving.  When you push it, it push the entire leg inside.
Maybe it so rusty it got stuck?

General Discussion / Sym Duke 125cc - front shock absorber rebuild
« on: May 30, 2021, 03:33:01 PM »
Hello,

I have an old scooter, SYM Duke classic 125cc.
One of the front shock absorbers is leaking from the oil seal.

I don't know how to open the shock absorber.
On videos i see on Youtube, you can see that the shock absorbers have like a cap which is a screw.
In my case there is no cap like that.
There is a black plastic/rubber cap which you can remove, and under it there is something else.
No screw to open.
See pictures:






Is it possible to rebuild this shock absorber?

Thank you.

The symphony 125/200 is fuel injected and also air cooled.
The manual for the  HD 125 is for a model with a carburetor and it's water cooled.

Is the tensioner adjustable?

No, it's not adjustable.
Here is a picture of it:


It's a chain and chains do wear and get longer... How much longer until it's beyond the service limit/your comfort level... I don't know.


I actually did an engine rebuild about 23,000Km  (around 14K miles) ago, and the chain and tensioner were replaced.

Thank you for the asnwers.

The problem that i have, is that the Cam chain is too loose for my opinion.
I tried to replace the cam tensioner, but didn't solve the problem.
When i removed the tensioner i noticed a small dent in the upper cam guide, where the tensioner is pushing against.
The dent is in the shape of the tensioner (small square).

Do you think this is what causing the cam chain to be too loose?

Thank you.

Hi,

I have the Sym Duke 125cc, which supposed to have the same engine as the Megalo 125cc.

In order to replace the upper cam chain guide, Do you have to remove the camshaft?
If yes, when you open the 4 head nuts, do you have to replace the head gasket even if you don't move it?

Thank you.

What is usually the size for the 125cc?

Thank you.

« on: June 09, 2014, 06:34:38 AM »
Hello,

I have a SYM scooter, the model name is Duke 125cc, and i think it has the same
engine as the Megalo 125cc.

I would like to order a magneto puller, but i'm not sure on the size.
Are all the SYM 125cc scooters use the same puller size? Do you know the size?
Also, is it supposed to be Left hand thread (reverse thread) ?

Thank you.
