Thanks Rich, I did not know that was a tuning item. A post on the Easykart board also suggested running with the rear bumper loose.
As a followup to the bearing question above, does that mean the bumper or the straight cross-piece? Does one just loosen those nuts (and they won’t fall out?) holding the cross piece?
As a sidenote: I have installed my decals (they look great), the motor is off so i could clean everything, I tried installing my seat tonight by following the easykart chassis setup guide, no dice. I have to come back and reevaluate my approach. Luckily I didn’t drill any holes yet.
