87sheestillkickin Posted April 25, 2016 Report Share Posted April 25, 2016 What type of riding you do? Billet bowls? Lots of factors there Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
J-Madd Posted April 26, 2016 Report Share Posted April 26, 2016 In 300 ft racing, billet bowls without pump is fine. Anything longer... yes. That being said, no downside to running a pump on that motor though as long as the carbs are set up for it AND the floats are set properly. On a tad bigger motor than that we run a pump and basically waste some fuel out of some barbs that are installed on the bowls. I had a hard time setting the floats where I felt it safe. It was either fuel level was shutting off too soon or would overflow through the vents (and into the motor). Many bog passes due to that. I'm not saying this is the correct way, but this motor is a rocket and I just don't want to change anything on it. 1 Quote Link to comment Share on other sites More sharing options...
JTmachining Posted April 26, 2016 Report Share Posted April 26, 2016 I use a pump on race mtrs. Also helps pull fuel from tank at all times Quote Link to comment Share on other sites More sharing options...
