hi. i need help deciding what i should do to my 01 300ex. i want to put a big bore kit on it but i dont know what else needs to be done. do i have to change anything else? Also can i jet the carb. or do i have to put the big bore kit on it first. what are good products that will give me more power. thanks

how much money are you willing to spend? go to www.fourstroketech.net for your big bore kit
if you want a new exaust i would recomment curtis sparks exaust its one of the best but with a high price tag
i would get a k and n air filter also

go with powroll 352 bb kit it has the rejet for the carb, you will need a white brothers e-series or equivlent exhaust, kit should come with everything else then send the head off to madman for some port n polish and valve clean up

I am very satisfied with my setup below. Only thing I will probably change is adding a 400ex carb, or at least try it out for comparison.
