Fuel smell after riding

[t38talontr]

After riding the bike long enough to get the engine hot my garage smell fuel terribly. I checked thorougly and there is no leakage sign. When it gets cooler odor goes away. This happens at all tank levels (full, half, near empty) never happened during winter. What might be the cause. After some search I realized that other brands also have the same problem and people say it may be beacause of fuel vapor or air cleaner.

Does the bike have an EFI programmer?

When the tank gets hot it will vent/drain out the tubes at the swing arm pivot bolt....its normal:thumbup:

the ecu does run the bike lean when its cold and switches to the normal map when the temp reaches NOT. which is richer.
Could be a leaky injector?
if you have done the CO mod try returning it to the stock numbers
the easiest thing that I would do would be to just reset the bike, pull the battery cable off overnight, then reset your clock, change it back to MPH and take it for a ride, see if anything has changed?

just spitballin ideas.... :BLAA:
im sure somebody else has another idea.....
