110v generator maybe 230v?

Just won a generator on ebay (Subaru Robin MG 750)
it is a 110v generator (looking at the 16A yellow socket) and the voltage.
however on the side it says 220v-50HZ 

It has 6 cables comming out the generator:

Red
Blue
Black
White
Green
Green

Label says 230VAC then it's 230VAC. The socket on it doesn't mean it's 110VAC unit. From what i can see it looks like the socket has been replaced. But if you really want to know for sure then crank it up and test the output.

tested the voltage comes out around 110v

So someone rewired it for 110VAC.
What else do you need ?

i need to know how to put it back to 220VAC!

Generators usually have two identical 110 VAC coils accounting for four wires..
Probably the Red Blue Black and White wires
In a 110 VAC setup these coils are wired in parallel
In a 220 VAC setup these coils are wired in series

I would attempt to verify and rearrange the coil wires to reach 220 VAC
as my first engineering attempt.
Also I would use a volt meter and ohm meter tracing where these wires
and that yellow outlet wires come from and go to/
+1
Also a 50 Hz supply is commonly a 230 VAC power system.
If its 230V, you MUSTchange that connector to a blue IEC connector, in case anyone accidentally uses it with 110V site equipment - it could be lethal.
I tried to find a manual, without success. Although I think I found the product page, here: http://www.mowlin.com.tw/product/100888.html

Just sort of echoing what everyone else said:  The markings on this generator say 220 VAC, and the yellow socket kind of looks non-stock, like it was added later.  So just the style of that yellow socket is NOT a reliable indicator of what kind of power might come out of it, and the best way to tell would be to fire it up and actually test the output.

Red and black would be the 12V dc, white and blue would be the AC voltage and green the chassis earth.
+1 for go by the label,
If you want to be 100% sure use a volt meter on the yellow plug
