air box lid, need help

[99'300EX]

right now i have my air box lid on, is it really worth drilling holes in it? will i have to rejet???

Yes it is deffinatly worth drilling holes in it.

i have a trick aitr box that i can open and close the holes.

Drill 3 or 4 holes in the back then take a sheet of tin that with cover all the holes and drill three small holes.

ONe way back. one in the middle and one up in the front.
You have to be able to put little scews throught them.

Then just when it is wet spin the tin around and cover the holes but if it is dry then open teh holes adn screw the tin down near the front.


AND YES YOU HAVE TO RE JET.

sorry for teh spelling i in a hurry
