High pitched noise in fuel tank

[BikerBoy]

Will Suzuki do it under warranty?

in your case.....maybe, but they'll say no at first. You'll need to arm yourself with the lab results and info I've provided and make sure you give them a solid argument. Your Busa is waaaaaay too new to be doing this!!!!. Problems like this should not start to occur until around the 40k mark. If I was in your position I wouldn't take No for an answer, give them a copy of the lab test data and then if they still say No....i'd be asking for the reason why IN WRITING.

See how you go, and no harm in trying.
