00-02 YZ 426, 250f FCR O-ring mod WHEN IT DOESNT WORK...the problem and fix

This is a video describing how I found out my accelerator pump was delivering too much fuel to the engine after the O-ring mod to the accelerator pump. There is a mechanical fix to shut off the accelerator pump after it's been actuated it's called the BK mod. Once I've gathered the supplies and made the necessary repair I will post a video showing how to do it and what you'll need.
