not to be a wet blanket...but often the stock set up is the best way to go. what sometimes seem to be simple modifications often end up causing a new problem (such as off idle surge or fatness). it all comes down to defining the problem to be solved. if you just want a faster bike, a simple carb swap won't likely be the solution (honda would have done that to begin with). bikes with racey engines often are less than enjoyable on the street. been down that road.
