I have a kfx700 V-force and i have read some of the forums and they talk about the air box mods like drilling holes in the covers i think if this is correct could some one tell me how big the holes have to be and where on the box?? if you have some more liks to where i can find other mods pleez share....

 

Look at my TPI Valve thread.
