TBH, I never let it run out of fuel, I just pit at those times and the tank was close to empty. Should I try a 6.0 or 5.5 restrictor next? Or leave it alone? Its still a whole lot of motor for a buggy. I want to get the hang of this 5pt, Its bad A. I dont want to have to invest in a different pipe though.
