The trick is to decide what is wrong about the bike for you, then mod to correct it.
Learning how to properly control the bike at low speed is a good mod and saves having to lower it, which affects the steering geometry, making the bike slower into corners. If you balance that by lowering the front fork yolks you restrict ground clearance and lean angle.
When you decide what you don't like and what you need to change, come back and ask how to make that change. Mods for the sake of mods is a stupid idea. Changing a slip on because you don't like the sound is a good thing to do. Changing it if you're happy with it is not.
