Hey guys been working on a 94 500ex bike in a box project I got for free. there is a 3 way valve under the tank that has 2 hoses running from the valve cover to it and then 1 hose to the air box. There is a 1/4” line that runs off the top of the 3 way valve as well. I assume it’s to pull vacuum. I know I’m missing the carbon filter box that sits in front of the 3 way valve. Can I eliminate that box or is it needed? If so, can I run a tee to the 2 lines coming from the carbs and another tee to the diaphragm for the petcock to allow fuel to the carbs? The bike Has started a couple of times but only runs for a few minutes then stalls. I feel it’s starving of fuel. The carbs are freshly cleaned, it has a new battery as well. I’m also waiting to r new air filter to come in so at the Moment there is now air filter on it.
