gasgas ec 125 cylinder

[eranmu]

Hi,
I nead a new cylinder for my bike ec 125 2013.
Gas gas dont have it so i look for in ebay.
There is an athena kit , but i noticed that there is a diffrens between them.in the original cylinder there is a valve with a pipe at the left side in the front that get out burning oil(i think).
In the athena cylinder there is no such thing.
Does anyone know why and if necessary?
Does anyone know if a big bore kit off yamaha yz 144cc fits?

The GG and YZ125 cylinders are very similar and the pistons and powervalves interchange but the overall cylinders do not interchange. You can have your cylinder repaired. It is amazing what they can repair on damaged cylinders. US Chrome does very good work and has reasonable prices. http://www.usnicom.com/

While you are at it you could have them make it into 144cc big bore for you.

X2 on what Zman said and /or you could send it to Eric gore and have him Big bore it.

Judging by your user name (and the fact that you have a 2013 125) I would say you are from Israel, right?
If so, sending it to be fixed in the US would be very expensive...
I bought an Athena cylinder kit from Mike Politi (03-6818556), he might have a kit for you.
If you want to buy it off Ebay, the correct Athena kit for your bike is P400155100001.
I didn't really understand what differences did you see, but this one is identical to the OEM one, other than the fact that Athena uses studs and nuts for the head (like in the YZ) and not bolts.

Judging by my bad english(and my username),
Yes i'm from israel.
Firstly thank you very much.
Asked about a yz 125 kit's because they are cheaper and are common

That is just a vent hose. Not necessary. On the 300s some people plug them.

Unfortunately I think it's not the only difference.
I think the ports are different as well.
When I tried to figure it out and asked the guys at Athena, they insisted it's not the same (and that's why they have different kits for these bikes).
As Athena is the OEM manufacturer of these cylinders, I took their word for it...

Did you check with Greenland MX online for a oem kit ? I've had good experience with them.

I've had good experience with Athena stock replacement cyl kit on a YZ 125, too. I wouldn't be afraid to use their product.

Agreed. They would not make it that way if it didn't work.. 99.9% of the time, anyway.
