I have heard two different advices on what is needed to get the extra 10 HP out of my motor. Has anyone on here done it and know what is really needed to be done? I heard everything from replacing carbs and intake to a simple carb stop adjustment and different intake spacer. The motor is a 2000 model. I noticed on the parts list that "it appears" that everything is the same with the exception of reed valves on the intake and jets on the carb. Is there anyone in central florida who can do the work and get the parts if it is do-able?

"intake to a simple carb stop adjustment and different intake spacer"

Completely false...What had to be replace varies depending on the serial number.
