Right on Brandon & Rex- couldn't agree more I don't know why some people feel the need to dump on a product that they obviously are not familiar with and have little knowledge of. Maybe that's how they get off

I have a mate I race with who bought a $700 motor (brand will remain nameless). This guy is a GOOD driver and a very experianced tuner who has a real chance of winning pretty much everything he enters. This "top" motor flamed out consistantly for an entire season, probably costing him a couple of big wins. All of the guys with Go motors don't seem to have much trouble at all, beyond the normal gremlins that happen to everyone. Sure this top end motor probably made .5 HP more than my humble Go 7 Port, but .5 HP is no good to you if it's on the starter box flamed out for the third time in 20 mins !
A lot of the carb problems were down to incorrect tuning due to a longer LSN which was introduced. Tips on tuning were posted on this forum that have solved all the problems. The motors run sweet as with long or short needles, just got to tune them right.
The Go is not a cheap knock off. There is a large amount of R & D going into new Go products all the time, from teams and development officers world wide. Modified Go's are being raced by team drivers in Asia currently and perform very well. Trust me, the Go engines are not going to fade off the market anytime soon. Phew !! that feels better - got that off my chest. Sometimes I just have a problem with knobs who continuously dribble off at the mouth Shane Adams
