  • Fuel Injection Puke?

    I have a '12 FI bike and lately when i come back from a ride and park in the garage it smells like gas for a while and then the smell dissipates. I've heard the term "carb puke" on the carb bikes, is there an equivalent problem with the FI bikes?

    That big engine is very good at heating the gas tank. What you're smelling is fumes from the vents. Mine is in a carport and when the sun is just right I can see the shadow made by the fumes after a ride.

        So it's "normal" and nothing to worry about?

          Yeah. Smell down where the vent hoses exit and you'll get a snoot full. Not too close though, it can get pretty strong. On California bikes the fumes are captured by a charcoal canister and sucked back into the engine when running.

            in FL with a black(fastest color) bike , from yards away, i can see the fumes coming from the vent tube under the bike, diffracting/bending the light from the volume of fumage expelled , albeit carb-ed bike, same tank system

                Hey guys he said it is a FI bike. I never heard of any fume issue from a FI bike owner. I would get down to finding the issue. If it is from some sort of vent I would want to know why it started to smell when it didn't before now and no one else with FI has the issue.

                  Make sure you are only putting in four quarts of oil or it will push it out. Don’t rely on or use the dip stick.

                    How is that related to fuel smell?

                  The FI bikes have 2 rollover valves instead of the one on the carbureted bikes. They are placed somewhere on the front down tubes. I guess that was a more direct route than the one on the earlier bikes. And yes with warm fuel fumes will exit those vents.

                    Just a thought I'd throw out,
                    I believe the charcoal canister is supposed to absorb any fumes from the vents. If you overfill the tank, it can dump raw fuel into the canister causing fumes to escape to the atmosphere.
                    The charcoal canisters are very expensive at $500. bucks a pop.

                      Yes they are but they are only on the California bikes. I think they're a good idea but I've read of some removing them from their bikes. Don't know why though. They're on on all of our cars nowadays.
