This winter I purchased a 2023 25/50 MGM out of Jacksonville Florida, it supposedly had a very neutral baseline setup on it. I took it out for our first practice recently and it was underivable, the brakes would instantly go to the floor and I would spin immediately. Then when I wouldn’t touch the brakes in an attempt to roll the corner it would step out. After that session I spoke with Paul Rice via email a few times and he advised me to add a torsion bar, new tires and up the pressure. I added the bar, new tires, bleed and shimmed the brakes, moved the rear tires in as far as the hub would allow me to and added weight over the rear axel (I’m hoping to run masters) and went back to the track Thursday. It was significantly better but still felt really loose, upon entry I would try to brake hard early and roll the corners. If I even barley turned the wheel while doing this it would lock up and spin, I then tried to trail break through the corners and when I would attempt to add throttle it would step out and spin. We race at New Castle and there was not one corner that I could take at full throttle without feeling like it was going to spin. I had to endure my 11 year old in his cadet kart (and he’s mid pack at best) making me look slow AF and he is NOT letting me live it down lol. I just want to be competitive mid pack and have fun and be safe for other drivers to be around.
I am 6ft 210 and I’m running a iMAF size 3 soft seat
I would be willing to pay for someone to help/teach me about this kart on a practice day. Does anyone have any advice to steer me (no pun intended) in the right direction?
You need to get ahold of Jamie Bradford or Eli Fox. Both are running your exact kart at NCMP and running well. Maybe they could take yours out for a session and see if there’s anything goofy going on.
Something is way out of whack. Your weights across front and rear should not be that far off.
Check through the following
Scales level
Spindles both same spacing up and down on each side
Axle is level in rear
Steering wheel was straight
If all are verified, you likely have something tweaked. Get it to a shop with a table and make sure you are started at a good point. Chasing a “neutral” set up and not have a straight chassis is only going to drive you mad. Not to mention allow the kid to talk smack
You’re a lot closer now. What did you change between the two scalings? Did you have 1 tire flat ?
Your kart is close enough now that it should be driveable. It is still set up to turn a little too well to the right. For NCMP, I would want cross at 49% and left at 51%. Where are your weights now?
With our MGM we could find a few lbs to move cross by simply loosening the LR cassette bolts and letting it move up in the hanger a touch.
Haven’t ran a 23 but we tried to have nose 43-44%. Try putting that 5 you need to add on back of seat and under front of seat and see what it does for the nose weight %. Easy change at track and if you know before hand what it does its nice.
In every configuration you do, the LF is light. I think you should get it on a chassis table and make sure you aren’t chasing an impossible set up due to a tweaked chassis.
