I'm fixing to change over my impulse for my son and was wondering if anyone would help out with a good starting point as far as setup. He's been riding a 06 Tempest and been really comfortable on it but I know its time to move up to something a little newer. I like the Impulse but always had a little push that I could not get out and was wondering if he will have the same, I kinda learned how to change my line a little to help it out for me but he's still in the learning process and not sure if he could do it on his on. When I bought the kart new I got the seat bar also and didn't know if I should leave it on for him or take it off. Thanks for any help.
