You need to learn how to tune your bike or you'll never get the power you want out of it, regardless of how many go-fast bucks you spent on it!
Buying a new bike won't fix the issue, because it'll still need to be tuned for changes in weather, compression, aftermarket parts, location, etc.
It might run good for most of the season, but what happens when it starts getting out of tune? Buy another quad???
There is no "one size fits all" jetting guide, as everyone's quad will need a slightly different tune, the most you can expect is a somewhat accurate ballpark figure that may or may not be safe.
Find a local guy to teach you how to tune or have them do it for you (make sure they know their stuff first!).
Nothing better than having your quad perform flawlessly knowing you were 100% responsible for that fine-tuned machine...
