Strange Noises

[martin.webber]

After 10 years of longing I have just taken delivery of a Chimaera and I'm over the moon.
A number of times when I first start her up I have heard a big thud from the boot area. Is this a normal sound. Sounds like the fuel tank is bulging or something - can anyone help?

Could be a pressure build up in the tank!

Next time loosen your filler cap before you start it, put it to the half lock position to see if it cures the problem.

If it does then get your tank breather checked out!

had the same thing on mine, but it just went away!
