You need to do a sheave upgrade which is a part of the CVT, Continuously Variable Transmission. Slugging the wet clutch will help with driveability and longer service life of your clutch.
Don't know what shocks were on the Sport Edition that year but if not the KYB's then shocks are critical. If you have KYB's you probably need new springs and shocks tuned by a shock shop. And it all depends on what type of riding you are going to do.
Download the Service manual and READ it.
Hope that helps you.
