Hi, I need help with the fuel tank filler cap breather system. I previously thought I had an oil leak, as there were small puddles on the ground under centre stand. Now looks like this deposit is coming from the fuel tank breather pipe. In warm weather fumes can be seen coming from the pipe, after a while the fumes seem to condense and there is an oily type substance dripping from the pipe onto the ground under. Eventually the puddle can become 4 inch in diameter. I dismantled the filler cap to check the airway through it. Now I don't know if all is well. Has anyone out there taken the filler cap apart and can give me some advice please. After removing the lock by taking out the two screws, under the lock is a round plate with 4 holes. 2 of the holes are for the fixing screws. Under the plate can be seen 2 recesses, in 1 there appears to be a ball. The question is should there also be a spring. Has any one else had a similar problem, the bike was fine all through the winter period and now I have patches all over a clean patio how annoying.
