25-30 BigOL3 ain't gonna be happy.
The Talon has an inner tube in the filler neck, it traps an air bubble, limiting the tank's capacity to 7.3 gallons (Honda's number, I never confirmed it). Removing that inlet tube lets you fill the tank right up to the top. There are some who experience a fuel smell when doing this but I've been syphoning gas most of my life so I was willing to put up with that for the extra rumored gallon. I've filled up 4 times since removing mine and haven't experienced this but you should be aware of the possibility. I bought the Talon for exploring the southwest desert, I need all the fuel I can get onboard.
What I did was to run mine completely out of gas (including the last little bit sitting on the trailer, so EMPTY). It took 8.612 gallons to fill, I gained 1.3 gallons - YAY.
This - (note that I terminally tweaked mine getting it out)
