Well, here we go again, on sale on ebay from a German vendor, this engine ABSOLUTELY does exist. Comes with the Efra 2103 pipe which was the last pipe they were selling with the similar engines.

This absolutely looks like an Arrow GTR with a purple head on it. So Cera does exist, and I'm pretty sure they are made by Go, just like SEG and Arrow were.

Hi Eivind,

Your third quote down hits the nail on the head.

It seems GO have a lot of discontinued stock that was scrapped and never made the market from when R Chen was designing and running the show.
They decided to release the new GXII Plus, but had a warehouse full of parts / motors etc that they now need to clear.
To the best of my knowledge this re released Cera has not been offered to existing GO distributors (not here anyway), but are coming out the back door to put some funds back in the bank.
Same thing happened on here a while ago with the 2 year old Underdog/Champion design that was being touted as an all new motor from GO.
It's the way the market works over there, as Rex (22Racer) mentioned.
Most Taiwanese motors have some percentage of GO manufactured parts in them or on them (their latest 2 needle carb is popping up everywhere, and the GXII epoxy filled crank is floating around in several models of motor it would appear).

It's all good. I simply posted on here what I was told direct from GO over the last year or so. The fact they have now changed their mind and are clearing the racks in the warehouse is a new, and to be expected trend. They are in business to make money, not to sit on old stock that has cost them precious dollars to produce.
It's a little confusing for the customer (and the distributors sitting on current GO stock), but this industry can be that way sometimes :nod:

What I don't understand is why, when Go have all this equipment and opportunity, why don't they make something that kicks ass, and stick with that.

I did speak with Robust on the telephone once and he seemed very fixated on ready-to-run and easier to use, and not at all focused on performance.

Yes, I believe that was his downfall.
He was talking about making a race engine that the Pro's could use with the ease of a pull start !!!
He lost my interest around that time. Why would a Pro driver want an energy sapping, one way bearing pull start unit hanging on the rear of his motor.

His other fixation was the ring less nitro motor. It seems all of GO's R&D funds were blown chasing this elusive product, to the detriment of other projects and the actual production of a new saleable motor (for around a year).

The Cera was to be the high end motor from GO, supposedly comparable with other high end European motors out there - but Robust got his marching orders before it was released.
Whether this "current" Cera is the original, or the shell of the Cera with different internals, who knows.

It's a shame, as GO lost a lot of credibility over that period with customers and distributors alike.
We took on the new GXII Plus in an effort to get them back into the market here. It's a good little motor at a good price, so we will see what happens.

Where can i get this engine. Is the porting same as arrow gtr?

.....

nevermind

Just bought a R21 5 Port Silver head to run in a MBX7. What is a good pipe for this engine? I have a Dynamite Platinum 053 and a Novarossi 2096. Also Is there anything I should be aware of with this engine? I am not really seeing any information on it.

Ask the seller. In the listing it says they speak English.

2072, frankly the dragonrc pipe produce good power s well

A 21 silver head? Do you have a part number and/or picture?

I got 1, it was old gx5r p/s/c. In malaysia there have the orange head which they said is limited edition. Good power for medium track. U can buy the 7port p/s/c for big track n directrepla

Hi Rich, Hope it's all going well for you in the US :)

That sounds like the old Pro Series R motor. The 5 Port was silver head, the 7 Port was orange head, and at the very end of that era they did a 3 port with a coral pink head. These motors preceded the GX Series 3, 5, 7 ports
Makes that motor at least 5 years old, maybe a little more.
Very strong motor. Only problem is the current sleeves won't perform as well in that older Pro Series crankcase. Current 21-0600 rods and the newer ramped cranks would fit ok.

Good to know. It is still brand new in the box but was old stock from what I understand. It will at least let me get a nitro buggy running this season.

If it's still new in the box it will be great engine to get going with.
The 5 Ports had brutal bottom end, so you won't be lacking anything in the power department.
One thing though - those motors were notoriously tight when new, so make sure you heat it up really well before starting it during run-in, and don't rush the run-in.
It will take a fair bit of fuel until she fully beds in (around 1 gal +, yep no kidding), but if your patient and don't hammer it until it's nicely bedded in, it will last you a long time.

Here's a good GO 5 port, based on GX5R I think but modded, this engine goes great.
