Thats what I think has happened:

Well here's a little chart I made a while ago not only for GO but a lot of other engines too....hope that helps

I've found the sport engine needle settings are pretty close to the race motors.

Rex

if your unsure the base settings on your needles are flush on the go techs it keeps it real simple for when you loose your tune reset and start again

Thanks for the info, you know how it is sometimes, just trying to get a little more out of it and then it won't stay riunning long enought to tune it, kept dieing at idle.
It was running around 230/240 degrees is that too hot? it had plenty of smoke and seemed to have plenty of power.

Nah..230-245 is about where all my Go motors like to be..they just seem to like runing a bit hotter than other makes I've tried..so long as you have good smoke should be fine..if you have problems holding a tune just do it logically..First if it's been running great for a while then won't hold a tune and you've adjusted nothing look elsewhere than the needles for the problem.once you've eliminated air leaks..loose fuel pipe..bad tank seal.shit in the needles .motor low on compression etc etc..then set idle gap 0.7-1mm needles flush and tune from the lsn...probably need to turn lsn in 1 turn to get it to idle from the start...

Hey Mr Giz, has your new toy landed yet ??? Can't be many sleeps away now if it hasn't arrived already.

thatnks for hte info Rex..got any pictures of the said process??

thanks

Dunno can't sleep waiting for it..keep finding myself chatting to mark on skype at 3am cause I'm still awake..so I'm blaming the wait..left monday but usually takes 8-10 days for packages to get here.I got mark to sling in the ceramic upgrade as well..I mean bugger the expense..I bought an MG66 why skimp at $50 aus more for the ceramic bearings..besides ate my steering servo yesterday.well actually ate the 1st gear on my hitec 5955 a few days ago and yesterday ate the crappy stand in which was all I had left that works..ummm worked.So static till the new gears arrive..should only be a day or two more..
Anyway the 7 port is about run in..put about 3 litres through it this week..neighbours are pissed off but thats OK cause they're assholes anyway..bet they'll be overjoyed to hear I got another new engine to get ready for the 6th september..YAY!

I just ground off about like 1.5mm off the lsn to try out and I rounded it of really nice and I find tune much easier to catch. This was a gen 4 carb I had laying around. These carbs were always alittle tough for me to keep a tune on. This is something I recommend to try for everyone. It to me gives the midrange much more pull. The new carbs I have no problem with I was just bored. The 5.5 carb I currently have I havent touched it for like 3 weeks. Thats what I am talking about. Also for temps, some Go's run at 200 some 245, I agree with not worrying obout the numbers if there is a nice amount of smoke dont worry about it.

love it. I'm a bit lucky the neighbours don't mind the run in process to much, just wish it would stop raining long enough to run in my rebuilt 5port.

our MG66's should land either today or early next week depending on customs and they're all presold- and no I didn't get 1 myself

ohwell theres always the next batch

Adrian

Picked my MG66 up from Mark last night. Lucky number 13... well my last name is Black! Man, it's such a good looking motor, I think I'm in luuuv..... How do I tell the misses......


Pete.

will try something, its my 3rd case this year and its getting old. no signs of contact under the motor on the chassis and all 12 screws were tight when it happened last. will the new series of motors have a differnt case or the same? i've run other motors and had no issues with other brands. it sucks cause i really like the go's feel and performance (and cost if they would last a bit more).

Look if there is a space between the engine and the engine mount. If the engine mount it's catching in the crankcase, this will cause a crack.
If this is happening, you will need to grind a little bit of material from your engine mount.

Guys, I'm in the market for a new engine for my Hyper 7. I've had my eye on the Go-Tech 5 port for some time now and I think its come time to purchase a new engine. I'm pretty tight on money, so saving money anywhere is good for me. Is it worth it to get the 5 port over the 3 port? Is just a weekend warrior driver like me really going to notice the difference that much? I am hopefully going to get into racing soon as well so keep that into consideration. Just looking for your thoughts.
