sweet, let us know how it perform. i will receive mine by next week:nod:

Gx2plus good with 2072 pipe?

Yep. 2072 is sweet on the GXII Plus. Gives the motor a little more bottom end compared to the new 2103 that comes with the motor in combo kit form.
The 2103 is more of a mid / top end pipe - but both give good performance.

2072 works fine! That's what I am running with my plus motor.

Sweet, thanks

Got my cera today and find out:
1. No additional venturi (9mm in the carb)
2. Crank shaft show some play like 2-3mm

Bought from ebay, need advise on can i use this engine with the crank shaft show some play when u push it into crank case from front. The play in very noticeable. Please advise. Thanks in advance

Sorted out. Help from Novarossi forum. Thanks anyway

You guys buying these motors need to be aware they are a warehouse clearance item - no longer in production with no (or very limited) spares - the same as the Underdog / Champion engines that popped up on here a few months ago as the "new" engine from GO - totally incorrect.

I believe GO has around 20 Cera units left as of last week. Once these and the current units out there in the marketplace (E-bay) are gone, that's it.

This is just FYI, as I wouldn't like to think people are purchasing these under the illusion that they are an "on-going" model with factory parts support etc.
These engines are not being sold through GO distributors (we were not offered them) - only out the back door via E-Bay etc.
I don't think the GO distributors out there have too much of an issue with this, as it's the way companies operate these days - but I just wanted to make this clear so it doesn't reflect back on us as distributors selling the current GO models in good faith, when you can't get parts etc for these engines further on down the line.

Out of my curiosity, will other go engine parts interchangeable with cera as i found out the p/c/s of underdog project is interchangeable with gx parts.

You would need to email GO and ask them.
As I mentioned, GO distributors (except in South America) have not seen these engines in the flesh, so will have no idea.
I'm guessing maybe the 21-0600 rod would fit - but not sure, as these were designed to be all new, and morph into the ringed motors after a short period - but that project never came to fruition.

Arrow GTR and GTRII plus parts will interchange. Crank turbo is slightly different but as far as I know, the Arrow p/s/r and crank will directly fit.

The rod length of the Cera is 30mm not 29.5 like the std. Go engines (21-0600). All parts should interchange with the Arrow Gtr.

not sure with the conrod but i did measure the sleeve:
1. height = 30.61mm
2. outer diameter (small) = 19.52mm
3. outer diameter (big) = 22.95mm
the sleeve cut is at the exhaust port.

so can it be conclude that it is an ARROW GTR PLUS?

can anyone share the break in needles setting for cera as i dont wan to mess up the first bump:
1. lsn
2. hsn
3. mid needle

Go 2072 pipe
 

Hello everybody,

would anybody have a second hand Go 2072 pipe set to sell with + shipping to Europe please?
It's for a 3 ports blue head sport model. Or any other recommended pipe?

Thanks a lot
