Re: Engine stalls at low rpm if fuel topped off
You have already been given the answer, I just want to add my comment that you should NEVER fill it above the guide ring that the nozzle goes through. That is to insure the proper airspace above the fuel in the tank to prevent overfilling, which can force raw fuel into the charcoal cannister, which is meant to only see fuel vapor. Raw fuel in the cannister causes very rich running until it is purged by the engine vacuum pulling air back through the cannister and into the intake to clear the charcoal of it's liquid. The cannister is meant to absorb fuel vapors for emmissions control when the bike is not running, and when the purge valve opens when the engine is running the vacuum draws air back through it to pull the vapor out and burn it in the engine. Raw fuel destroys the mixture control until cleared.
Also, if enough fuel gets into the cannister it can cause it to clog up, then nasty things happen, like vacuum collapsing the tank, running the engine very lean, and bending the fuel level sender float tube.
