You need to read through the past posts on this message board. There is so much great information here that it will be hard for someone to just lay it all out in one post. Also, there are a lot of differing opinions on what works best. If you come up with a specific question on something, feel free to ask it.
You should start with searches on the following topics:
Exhaust and Airbox baffles
Powernow / Jamesnow
GB Mod or BK Mod
That should get you started. BTW, a lot of these mods are the of the cheap variety and they will help you get your bike running the way that it should. Then you can start to look at all of the extra goodies (Steering Dampner, Various Guards and so on.
I hope that this helps and good luck.

I first started with a 48 pilot and a 155 main. It ran pretty good but there was still some popping on decel. It burbled off idle and went flat on the top, and was hard to start when cold. I changed to a 158 main but it was still flat on top and had some popping. Went to a 50 pilot and fuel screw out about 2 turns. The burble went away, no popping and it starts every time, but was still flat on the top end. I then went to a 160 main. WOW... this thing has some serious top end now. For riding over 3000ft. I would go back to a 158 main but for 0-3000 the 160 works good.
