sounds like Ron's needle balance artical:nod:

I was just wandering about these engines.
I am looking for a good mild not wild .21 for my Caster ZX-1R.
I am looking for a motor on a budget... Under $200...
Found a couple on ebay, 5 port or 7 port?
I was going to go with an OS VG but am curious about GO engines...

Thanks!

5port more bottom 7port more top 3 port smoother.

I run the 3 port in my Caster Buggy, it's all good:sneaky::nod:

Justin, have you seen the inside of the new 5 ports, very nice:nod:

Thanks alot Brandon, Will investigate futher the LSN settings.
Great article!

Cheers

Where can you get them? Amain is backordered most of their .21's...
There are a couple on ebay... Any place else carry them?

Thanks!

Dont know I get them from the Factory cause they sponsor me best thing to do is go to the RaceFactor website and look to see if the distributors are on there.Pro Twiser Mods is a distributor ask him he is Mugen.

Any special tip for break inn ?, i will receive my GO Engines this week ...

cya !

I found them on carolinas, but I might go with the one on ebay for the money a better deal for the same motor... Thanks!

Use a heat gun to bring the engine temps up to about 200 degrees F and lots of after-run oil.

If you buy from ebay, make sure the seller is an authorized dealer and and make sure that the serial corresponds to your country (for example: US000123 or AU000123) or you will not have warranty coverage. If yoiur going to buy from ebay, buy it from Luis Vazquez at PBloverz. He is an authorized dealer.

This was the one I was watching...

That is a pretty good price for that engine but I don't think he is an authorized dealer. When I was looking for a Go Tech, I e-mailed him and asked him if he was an authorized dealer and if the engines he sells had serial numbers. He never answered my questions. Also that engine he is selling might be the older version with the carb that had the leaking issues. I also thought he might be the owner or operator of RC Toro which sells Go Tech engines without serial numbers. Stay away from them too. BUYER BEWARE if you get your engine from either of them.

Your better off buying it from Luis Vazquez at the link I posted earlier and make him an offer. I doubt if you will be able to buy a Go Tech 5 port .21 for less than $180.00 from an authorized dealer.

Hey guys, my uncle asks if its possible to make the stock Go 25 6 Port turbo? thanks.
