just got toomey (jets)

yeah the kit comes with a 310 so if u take ur air box lid off u should be fine, like bigdblaster said
 
i tried it with the lid on when i ran the toomey system and i didnt have the vents and it ran like complete sh*t. would only putt around then bog out. ditch the lid and get outer wears or rap your air filter with a book sock or something else to prevent a little more dirt from getting through
