Good point Magpie-121, plus there is the Aussie GO Forum as well - so that's three sites to scan over. Bit much really.

I was thinking of starting a new thread for the GXII-5RHO motor on here when it is released, as this is really a different motor to the GX. With the three needle carb it will require different tuning tips than the GX long needle, and all that will do is confuse people if they are reading two lots of tuning info on the same thread. It was bad enough with the long and short needles without throwing a 3 needle carb in there as well.

What say we replace this current thread with the GXII-5RHO motor thread and have all the GX info on the new US thread. That will also get rid of that darn GO-Tech label we keep getting stuck with. I can get hold of Massive and have him change the name, seeing as he is the thread originator.

i think its perfect with the 3....the Aussie= great info for the aussie guys, the usa= great info (hopefully) for the USA guys...and this thread should be the ALWAYS GO TO thread for ANY INFO on Go Engines....but i do think we should all protest to get the TECH removed from this thread ....the GXII 5RHO, i dont think should have its own thread...but i see what you mean about how it might start to get confusing here soon...lol

I will say this for this thread. If it wasn't for this thread I would have NO CLUE AS TO HOW TO TUNE THESE ENGINES!!!!!!!!!! What parts work with what. I would have never found massive mods who's web site has given me great info on tuning these engines and the little secrets of them. Then there is Grizz/Rex[racer22] and a host of others. Who with out their knowledge I would be still trying to keep one tuned and running. Hell I only run 1 gx engine a 3 port that Rex is modding for me. And I haven't ran that yet! My gen 5 engines are all still haul-in ass along with my MG-66. If it were not for all the gathered info on this thread none of us would be as far along as we are now. I don't see the gx line getting shoved aside any time soon. So start a new thread for the 5 port ho engine or what ever it's going to be called. But lets not forget where we started.And understanding the older models will only help with the newer ones.

I don't think removing the "Tech" from the title of
this thread would be that big of a deal.
But I don't think starting a new thread for the GXII is
nessesary just because it has a three needle carb.
After all, most of the 886 pages of this thread has
been about carb tuning. So the three needle carb
should be worth at least another 400 pages or so.
This is one of the longest engine threads on this
site, lets keep it going a few more years.

Ha ha - yep your right there rageworks, the amount of disscusion on the carbs and needles on this thread has been epic
This is all the sort of feedback I was after. Looks like we will just have to add a few more icons on the desktops then to cover all the various threads.

Combining the new GXII on to this (and the new US) threads will probably work, as it appears the trusty GX won't be getting produced for long after the new motor comes out. I was told they have good stocks at present, but as those stocks run down they will not be replaced. Parts will still be made as required for some time I would imagine.
Those that already have the GX are up to speed, and most of the new GO owners in 2011 and beyond will be running the new motor (which is only going to be produced in 5R version it would seem). I am told GO is committed to the development of hi output 5 port motors for the foreseeable future, so a matching 3 or 7 port version is not on the cards.
So, after 6 months or so, this will become the GXII thread by default anyway

My rule of thumb for 3 needle carbs is don't touch the midrange at any time and just tune em like a 2 needle carb, the mid range isn't actually a needle but rather repositions the jet so the low needle is more tunable from low to mid and when the highend transitions.
All the guys I help out at the track also run OS and Ninja's wich are 3 needle and I tune em all like a GO anyway, except one that the mid had been moved (carby strip down and cleaned) I had to bring home and reset it and then retune from scratch.

If I get a GXII I'll probably be putting a MG carb on it anyway, I'll have to wait and see what they come up with first tho. and how it performs for me.

+1 Flanno. That's the key to the 3 needle's I believe. They are set in the factory and best left alone. The only one I ever owned I dot punched a reference mark adjacent to the adjusting screw and then never touched it, and it ran great like that for the life of the motor.
I guess they are going to the 3 needle style carb for better tunability and economy ? I have to say I find the 2 needle MG and GX carbs great.
I will definitely be trying one of the new motors (as you would expect being a dealer), so I will be very intersted to see how they compare to the MG, which is by far the best motor I have run so far.

Yep thats the trick with the mid range, mark it rite off the bat where it's set from factory for referance to go back to if want to play with it, also the mid range turns in 1/2 turn increments so ya need to keep[ track some how on how many 1/2 turns you move it in either direction.

Thats why I said if

I'm running the MG66X again for Mark in 2011, with great pleasure I may add,
I may (out of curriosity) get an GXII just to try, I'll let ya know what I think of the new carby IF I get the opportunity to try one.

A M2C 4 shoe clutch system arrived today to try out also, man talk about tunability.

I would assume that Mark's Gen 6 replacement for the MG66X would use the same new carb as the GXII?

No idea where it will progress to or if it'l stay the same.

Thats some thing for Mark to answer.

I like it as it is, but I'll run what he wants if thats where it progresses too.

I don't think you will find a new MG progression coming out any time soon. I asked Mark a similar question last week (in lieu of the new GXII release). His reply was - if it ain't broken, don't fix it, and I tend to agree. The success we have had here in NZ with the MG66 in club, and more so national events last year, was brilliant. Why change a winning formula.
You may see some slight cosmetic changes perhaps as time goes on, but the internals look set to stay as they are while the motor is as competitive as it is.

No we have decided to stay with the original MG Carb. We have had great success with it.

I'm confused why they would go to a 3 needle carb in the first place, as Flanno and Grizz have both said, the Mid range needle basically gets left alone anyway, so why have it .

Not that it matters to me at this stage, my 2 new MG66X's should last me a while

United we stand , divided we fall .. Dont be a stranger Trey ! you are always welcom in here.

ohauna!...(hawaiin for FAMILY)
