Tips for hissing fuel cap

[AlexD333]

So even with lots of fuel sometimes after a drive if I open it up I get a big hiss... There is a breather in the cap by the looks of it, I tried to spray it with brake cleaner, isn't there a secret hose somewhere I can spray?

You don't fill up enough then Mine gives off a hiss every so often but it's mainly in the summer when it's hot but never noticed any problems TBH & i'm sure a couple of my old motors would did it as well

Well this is fairly normal, there is a valve in a plastic cannister that looks like the old 35mm film canisters, it is attached to the fuel tank, and you will see a small 6mm diameter pipe on it.

If at any point you have starting problems or running problems, then removing the fuel cap for a second might help things.

What is clear... your fuel system must be fairly air tight, as any leak would equalise the pressure in the tank.

It's a full tank on a budget, 50/50 mix

I use the bike to commute to work mainly so the fuel build up in Terrano for the UFO hunting spots

You got one free with so many gallons of Esso petrol.
Then there were the stick on bullet holes too.
The Esso kite in the Mid 60's was the best ever I had.
