Fuel cap

[Don Williams]

How does the fuel cap vent and cam they be tested?

They can be cleaned. Remove the two screws to the black plastic latch cover. You will find two more screws on a little plastic tower with a hole in it. under that there is a brass plate with a hole in it and a plastic disk under it with a hole in it covering the hole that vents under the Chrome top of the cap. It's a vented baffle system so fuel doesn't splash to the top of the cap. I believe there might be a small ball bearing in the little tower. The cap I looked at didn't have one but the cap on my bike makes a small rattling sound when shaken and I seem to remember one. At any rate as long as everything is clear and not gummed up it will vent.
