i notice on some quick sweepers turning left mostly, that my front left wheel comes off the ground quite a bit, on my 125cc shifter, kart feels good, but i can only put down 80% throttle coming out of corners from a push..

32mm chassis no rear bar, do have side and front.
med axle med hubs, caster is aggresive.
415lbs with driver im 6 205lbs. 2 strut tight per side, seat is just under frame. 13psi yellow cold off track 15.5 all 4 corners.
stock moto set up with swedetech stock moto muffler.

Thanks

The only way the inside front tire can come off the ground during corner is because of big countersteer from oversteer. Or if your frame is massively bent.

Hard to diagnose over internet of course. Is the track gripping up? Wider front track width will give you less lateral load xfer, so you could try reducing widening the front and removing some caster to balance out the increased jacking effect from the front width increase.

Could be seating position as well, throw some towels behind your back and observe the changes, see if you like them. FI you do, move the seat forward.

front is set at 46" my seat is 25.xx rougly both side and top seat to axle was 10.2 wich i dropped now to 8.5 " seat is 1/4 under rail.

would removing side bar help chassis twist and keep it down. that track is grippy.

Reduce caster until you develop a bit of an under-steer, then back-up on the adjustment a tad.

I found positive caster gives you grip but to much will lift the wheel. Is it possible that your castor was increased for grip to over come another problem? I think I would try reducing castor and if you get to loose look to other changes to get the grip back.
