    I have been playing around with a cheap chassis for about a year. Heavy kart and driver 440 lbs, low hp clone BSP. What works for the lighter karts does not apply for me on basic set up. Any direction would be appreciated.

    Hi John,

    At that weight and with the engine selection, the goal would be to just work on keeping your driving smooth. For me, there would not be much to change other than track width at the front and rear, along with tire pressure. Those are your basic changes to make, then from there start working on ride height and front end geometry.

    Thanks David.

    I have built in every adjustment possible and have found that 44″ in the front and 55″ in the back works well. The steering is set up with the most Ackerman available -zero toe and 1 degree positive camber. All the adjustments are done with 200 lbs in the seat to simulate the sumo driver. Making the kart free in the rear has never produced faster times just inconsistent laps. At our local track my lap times are .5 second per lap slower than the #1 qualifier but the 50 extra pounds has a little something to do with that.  Still I want to get the most out of what I have.

    I agree with David. Set the kart up completely neutral and focus on driving it smoothly. With such low power and such high weight, the kart is probably never going to work as it’s supposed to.

    My dad is probably about 410 suited up in the kart running LO206 and he’s finding that chassis adjustments don’t really do much for him.

    Thanks TJ

    Your dad’s kart less the extra 30 lbs. is where I am at. How does your dad qualify compared to the rest of the pack?

    He hasn’t raced yet, just practice days so far. But from what I hear, there’s a lot of guys pretty far overweight in the LO206 fields around here, who are just looking to have some fun and drive.

    I would like to offer what I have learned over the past year or so to see if it will help someone else. Basically to prove what I have changed will work for someone else and validate my results.
