I got everything for the BK mod last night and going to talkle it tonight. I do have one question. When the gas continues to spray after the throttle is let go, what happens to that gas? I've taken carbs apart many times and started to think about it. What I came up with is that the gas still makes it to the cylinder put isnt used efficental and thats what causes the boggieness (sp?). I wonder what kind of fuel gains are made? Has anyone tried seeing how long a tank lasts? I'd be interested to know. ------------------ 01 WR426 Uncorked.
