on your carb you should have two vent lines coming out of the carb parallel to the slide body take one of these (ALL THAT IS NEEDED) and run it up to the highest spot possible and your done what class are you entered in? if it was like last year and right now it is very dry the only issue you might have is if Blair (event organizer) is running all the classes through burnt river to the sedgewicks pit there is doesn't matter what you do to your bike (its all up to the enduro gods) good luck!! watch out if you have an early minute David knight is suppose to be there this year for gasgas .
I am not going to argue with Dave that one is enough, but will note that I have been doing the more complicated T-fitting forever (since I saw mention of it in the late '80's) so both sides are vented up and down. For the newer Keihins that are (effectively) teed from the factory with 4 hoses, I again route one up/one down from each side.
Actually, I will argue a bit
.
I agree that one side is enough for water crossings, assuring there is always a source for air (from above) to enter carb. The original reason I saw for T's was actually to avoid bog on G-out or jump landing. The cause was that a column of gas might be in the hose at time of jump landing. The force of landing would slam the liquid out of the hose, momentarily creating vacuum in wrong part of carb (like sucking on a straw). The T prevents this, but needs to be done on both sides.
