  • finally figured it out...I think

    So I was having the occasional hesitation in throttle response and she was not running as well as I thought that she should...Then today she wouldnt get any fuel at all. Took apart the fuel tank and pump and what do I find? A bunch of black jelly in the bottom of the tank that was once adhesive...So today I ordered new filter and gasket(after spending nearly an hour cleaning all this crap off) and am anxiously awaiting the new parts. I am hopeful I gain a few ponies out of this and a smoother ride. Who in their right mind would use this crap?

    Did someone use silicon sealer on the pump gasket?

      I know...Maybe he had a good reason but the flange looks good after a proper cleaning. With a new gasket and proper torque sequence...she should be good to go. I hope!

        Y'all might want to change the filter while you're in there too or do the external filter mod.

              Sounds just like what I found in my bike! As mentioned in help section. Hopefully it didn't ruin your injectors like mine!!!!

                  Not for me....Personally I dont like the idea of running my fuel through a hot piece of metal before entering the throttle bodies.

                      Why would that be?

                        Boiling point of gasoline
                        The boiling point of gasoline varies. At atmospheric pressure, it's between 100 and 400 oF. A primary cause of this variance is the various additives in the gasoline from different refiners designed to meet different octane requirements.

                        Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines. It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult. The fuel can vaporise due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude." Straight from a wiki page. As I live in an area that is really not conducive to any living organism....let alone a fire breathing vtwin, I need to keep my fuel as cool as I can. Inside a gas tank covered by gas seems like a better place for a filter than snuggled up against the motor.

                          Never thought about that stuff. But would the cheap fuel boil more easy? And at 100 degrees F it would boil in the tank on hot days?

                          I pressume once it's all liquid into the pump there's no problem because the higher pressure will up the boiling point a lot..!?

                            Go with the internal filter..........AND BY NOOOO MEANS, USE ANYTHING LESS THAN 93 OCTANE! Makes the bike run like crap.
