can you hear it clearly if you take the gas cap off?My rattles also at times. It's the vent tube inside the gas tank.
Well.... I just got an ear-full of petrol while sticking my ear in there...... then I stuck my ear on the tank and all hear is like a U-Boat noise... gossshhhhhh.......... fuel pump?My rattles also at times. It's the vent tube inside the gas tank.

My top end, lifters & trans only have about 1500 Miles... those were all done by Andrew here in Spain.http://www.bigdogbiker.com/threads/she-lives-to-ride-another-day.15072/page-3#post-219022
Could your dipstick not be tight?
Checked! I dunno what else to check........ I´ve been almost a week chasing this little mouse!!!Hey Franco, check your passenger pegs. The right side will sometimes vibrate on the pipes and rattle like crazy. Just a thought....the mounts maybe loose too?

Had a rattle going to work one afternoon, mainly on acceleration . Panicked, went back home very carefully, smart ass kid looks at it and says " why is your gas cap loose?" Was feelin to stupid to kick his ass for laughing at the old man.Nah... there are no rattle noises... just weird voices!![]()
Thats what I was thinking, also check the upper motor mounts..Checked inside the fuel tank?
Ask Ambassador Raywood....
