100% correct.

The G5T was only a limited edition motor. It is no longer being made.
A-Main and us down here in NZ got the last order out of the factory - we only have 18 units left ourselves.
Great little motor for the price. You guys have summed it up pretty well as far as the bottom end and top end.
It's not the GXII crank minus the epoxy as far as I know.
At that price you could afford to throw a GXII crank and 3 needle on one.
By the way, the G5T with the grey crankcase looks very cool with the GXII head and finned button fitted too - very exotic looking. :cool:

GO have something new coming out very soon to replace the G5T. Along the same lines - affordable entry level, but still competitive. 4 Port (4 + 2) sleeve I am told. Should be out in the next month or so.

Hi Grizz :)

I knew you'd be onto it ;)

Hey Flanno - hows it going bro ?

I've not been on here much lately, so thought I would drop in and catch up with the gossip.

Will pop up from time to time when I hear any news from the factory that will be of interest to the GO faithful on here :cool:.
The GXII's are still kicking arse around the traps over here. Smooth and reliable as always :D

I'm still here Bud. ;)

Still having fun. :)

Have had some bad luck of late,
but still giving it my best effort,
looking forward to NSW Titles in 2 weeks.

hi all, how mm of shims should i use for the GO GXII? im running 25% nitro and engine fully broken in.

They still run great with the stock shimming on 25%

But if you want to take out a shim....

Take out the very thinnest one (brass 0.10)

Mine stock has 2 shims. 0.3 and 0.2mm.

alloy 0.3 and brass 0.2 ?

total of 0.5

did it come with a brass 0.1 in the box ?

replace the 0.2 with a 0.1 for a total of 0.4

Use a good quality glow plug, I was running a .4 shimming and it seemed to knock the coils out of the glow plug. I suggest a werks #6 ... OS p3 &p4's don't last more than half gallon. These are just my findings.

Quite possibly not FULLY run in yet...

or

It's not plug quallity thats the issue, but rather the fact that a Werks 6 is colder than OS P3 and P4s

The Hotter the heat range of a plug the wire element is thinner, and cooler it is thicker, therefore stronger.

I use O Donnell plugs with no issues Medium and Cold T97 and T99s

Hope that helps

I would stick with the std 2 shims while the motor has lots of compression and run the OD 97T plug if you can, the GOs love them aye Flanno :nod:

see post 2616 above.. first sentence. :)

True that Craige :nod:

Is there a place to source GX-7R cooling heads in the US? I'm having a problem with the fins breaking at an alarming rate.

i have found a few on ebay for 5 bucks brand new.

Thanks! There are a couple 5R cooling heads on there now are they the same? Will any other manufacturers' cooling heads fit?
