was getting into looking into things and it is time to check out the float bowl. bought bike 7 days ago and have no idea how long it sat. taking off the air filter housing and then the base plate. had to remove 2 looks like banjo bolts going into the heads. one is good the other is buggered up. missing o ring with silicone on it. also the area where the o ring goes is damaged. what is the purpose of this line? and where to get new bolt and o ring?
