I have a 2000 honda 90 and i got it when i was 9. Now I have out grown it and i just wanna make it a little faster and have some fun with it. Alright, I need tires def. these are the parts i am thinking of getting:

New Exhaust, either the FMF powercore or the Big Gun evo
Air filter: K&N
I dont know what else to get to increase some power. Suggestions would be quite hopeful. O and links would be awesome.

Parts I definetly need: new bumper (hit a tree recently), Tires, and maybe a chain guard.
