Bubbling Noise

08-09-2010, 07:47 PM

My tank makes a weird noise after it has been raining. No performance issues. But it only seems to happen when when I stop. It stops for a bit if I open the filler cap. If It has stopped and I jiggle the bike it starts again.
Any ideas?

Are you sure someone hasn't swapped your tank for a moonshine still?

I'm guessing it's just petrol fumes from the tank pushing rain water out the breather

But there is nothing dribbling on the floor and it goes on for about 15 minutes on and off ....

is that under the tank or in the tank?

Either, the filler-neck drain in my plastic tank used to get blocked all the time until I drilled to aluminium coupling out a bit. With a metal tank it's more likely to be a trapped hose.

Sounds really like a fishtank... Do you have a fishtank fitted anywhere on the bike??

Have you tried chewing your food a little more, maybe some prunes?

Failing that alka seltzer might help.

Wouldn't prunes just make it worse?
