Those o rings need changing frequently, They can throw the bike completely off and is not known about by most here.stillrolling wrote:float seat o rings. Take the float seat out where the screen is and there is an o ring around it. Took me months to find this solution. I experienced smoking, fuel under bike, back firing, and just running rich as hell. Some times it would run perfect though. That's why it took me so long to find it. My rear jug was the culprit also. Since then I have fixed several intruders with the same problems and when I flip intruders, I replace this o ring before selling them. Seems this is starting to be a common problem with intruders since a good many of them are starting to be 10 to 15 years old.
good luck..............
If my pump does not stop totally and still just clicks occasionally with eng NOT running prob got an o ring gone.
