Helix 150cc
Hello All,
Recently purchased Helix 150cc. Great kart. Only 1 problem took it in the sand trails and it didn't want to get up in go with 2 people in it. Had to get out and push it up hills and bogged around. Regular trails was better but still seemed like it had lack of power. 1 person was fast and power. Everything is stock. That normal for this kart with 2 people? If so, what type of mods should I do?
