they were put on to stop carb icing in cold/winter temperatures. i'm sure someone on here will have blocked them off,and will know if it affects them or not
Just take of one of the tubes from the cyllinder head, And take the other tube around so it goes to where the first tube used to be, So the water there just circulates between there.
I did it because the 34mm carb doesnt have anywhere to put these tubes
