As a frequent reader and seldom poster on this thread, this can be made to look like the truth, the internet always has a way of bringing out the negative in people.

HOWEVER, I think the people who got a Go engine and immediatly started complaining about the tune came from other motors that may have different settings or ways to tune them. I just got done breaking in a 5 port with the STOCK carb (properly sealed) and just putting an aggressive tune on it. The thing tunes fine, idles like a champ, doesn't "bog" like some say, and I'm sure it will last 6-8 gallons like the last one did. Some people get longer life but I run mine for max performance due to the competitiveness of the races I go to. It's not uncommon for me to run 270 in the summer and it keeps on taking it.

Every motor is machined, and there is margin for error, but it isn't frequent. You'll read problems with OS, Nova, Werks... on any forum and alot (not all) of the time it's related to user error.

If you feel you'd rather drop another $100 for the "real thing", then go ahead, and you can join their thread when you do. Having you go there and losing your negative buzz here is better for GO than having you buy one motor and keep dogging them here. Did you get beat by one and now your upset because they spent less than you? I see people spend $400 on motors all day and they won't even get off pit road without flaming out, or they suck dirt then blame it on a POS motor, happens all the time, and the web is where people take their frustration out.

I ran a whole season with great performance and results thanks to a great budget product.
