Pipe---sparks/dasa... both put out best power with drawbacks of being alittle to loud if db's are a problem at your track
hotcam stage 3-- for all around power!
engine work--baldwin--- great work quick return
maybe some different sprockets depending on the track

shocks--- pep or works if your not gonna dish out the cash if you are tho i would go elka!!!
handle bars--- a must and just go by comfort some good brands are (fly racing, flexx, and my favorite pro taper)
tires/rims--- itp rims on some holeshots also made by itp
nerfs,bumpers and all that good stuff really matters with the color scheme more than anything
but really you cant just jump into everything you want unless you tell us how much cash is gonna be spent on it... low budget? high budget? give us a clue and we can add some more stuff to help you out alittle more other than that all i can do is kinda give you a idea of what some basics... with the 05 i think there are some free mods you can do to it without even spending cash as well
