sorry hit enter by mistake, i have a completly stock 02 400ex, i just got razar tires and am wondering whut would be my next performance upgrade, and is it rely hard to mount tires on to the stock rims? also i am thinking of buting black plastics for my ex dose aneyone have aney picts of them on a 400ex (with headlights?)

 

for u first mod on ur 400ex umm id go with new pipe somethin like the whitebros e series and get a new airfilter those are the first main things u should get

 

yeah i'd go with a pipe, k&n filter, and jet kit.

i change the tires myself cause i got the equipment to do it, but stock tires are the worst i've ever changed, it's like the factory puts glue around the bead at least that's how it was when i changed the tires on an 04 warrior
