Save the money and tune/adjust the carb you got. It's perfectly capable and you're not going to see any performance gains with an aftermarket unless you go with a bigger diameter. Even then your gains will be minimal.

There's no guarantee that the Edlebrock carb is going work any better then your stock carb. It would have to be tuned or adjusted as well.

What's wrong with the stock Keihin? A carb is a carb, if the jetting and tuning isn't right...the bike will run like crap. Buying a whole new carburetor will not fix your problems. The only bike I have seen real gains with using an Edelbrock carburetor is the Honda XR600/650.

The stock Keihin FCR carb is among the best there is. It are much better than the Edelbrock with more adjustments available to fine tune all throttle openings from idle, to off idle, to midrange, etc.
