I have the vf700s with carb problems. while in the cleaning process i noticed i had 2 differant main jet holders. i'm assuming the reason for this is that the front 2 carbs (2&4) are down draft and the rear 2 (1&3) are side draft. The holes down the side of these holders are in differant positions . i dont know which 2 go to the front and rear. Someone please help!!
