It would help if you could get some pictures with a little more detail. Especially, the front end, wheels, steering wheel, seat area, and the rear where the axle is attached to the frame.
looks like a new breed sidewinder.
'a very desirable kart.
better pix would help.
from pix i can tell something was done to mount the garbage four stroke,
rims look wrong at least in back and swing arm may be missing.
still a kart worth getting at first look.
if you pass send me info as i always can use margay parts.
