I got 6.5 as the smallest in the MG's box..If not I'll be hunting a 6mm down online..

This is the maddest thing I have ever driven..It screams like a banshee after just 3 liters..pinch feels little reduced from brand new..I think the fact GO relaxed the initial pinch on their motors is a fabulous idea..easier on the starter box and less stress on internals period!

Oh how will I wait 2 gallons for the ceramics etc..more to the point how will I keep it on the ground!

I made the suggestion to go down to 5 , 5.5 and 6 mm venturis about 6 months ago .. I think Simon Yii is designing a new set for the GX range which will be awesome ! ive seen some of his designs so far and they look goood ! Nothing released yet as far as i know .

With the MG66 we will be releasing our own set of venturis for the engine , we have designed a set of 6 for the MG66 . Normally reducing the carb throat gets more thank time but we have peopel getting 11 mins with 8 mm out of the box so i think 6.5 is small enough for this engine.

As far as i know, GX series are 6.5mm, 7mm, 7.5mm and 8mm carb inserts.

Usually on a big track where i practice, i do get 08.45 minutes of runtime, and i tried this :

- 7.5mm venturi
- 1.0 clutch spring (were using 1.1 before)
- VP PRO EFRA 3023 pipe
- 75% carb opening

I ended with 11.15 minutes of runtime on my 7 port engine, and at racing pace i didnt have any problem with RB's, Novas and OS's around me ...

cya !

My Go .25 6-port just came in from AMain. Came with a break-in shim and instructions, but no plug. :weird: I must be gettin old...lol... back in the day all of my OS and RB stuff always came in with plugs and accessories. OS #8 it is...medium-hot.

I can't wait to get this thing on the starter box!

okay I can wait for local supplier. probably be amian hobbies in Chico Ca. I do believe he is the biggest online dealer in the states.

grizz1 09-02-2009 07:49 PM

Worth the wait Matt :nod:

Our NZ distributor sold out his first order within a few days, and their queing up for the next batch :D Now peope are seeing how easy the motor is to run in, and the performance that's starting to become apparent as they get a few litres through, the second batch will probably go in a similar time frame :D
