frankly,
all I can think about is the yoshimura brabble and if that's a K4 or not..
kart... uhm why is the rear bumper the wrong way around?
that way the inrushing kart would be deflected right into your neck...
which is generally not considered a bright idea in a kart crash
you rather get lifted onto the steering column of the incoming kart
..just saying
Also: kawasaki-green ... you should know better *giggle*
Well dang.. where was I?
right kart... now the issue with modern style race kart chassis is simple:
"they all look very much alike" there is little to no distinct differences that make one kart stand out from all the others.
So identification will be terrible.
unless you need a FIA document to make it racing legal
I don't see a reason for asking tbh.
it's some -more or less- generic racing kart
if you find the chassis homologation number that's always stamped onto the frame
you might be able to find it in the FIA publications.
Other than by a number there is little chance to positively id a kart like that
you'd need a stripped chassis
(no seat, no engine, no steering just bare chassis..) and a top shot pic
to compare that to known karts.
that for example is a fairly recent tony kart (401R IIAC far from yours I know.. just to get an idea of the pic you would need)
its sometimes as little difference as the location of mounting tabs,
a design pattern on the lower steering mount, the length and shape of the third rail..
And worse: there are not many such pics freely available.. fia documents is again the only known constant source.
(mfgs like their kart pics for "public access" taken fully equipped and with all the fairings and bumpers.. every bit of the chassis is obscured)
Now..
is that a TRS slip on yoshi? how does it sound (I liked the RS-3 myself alot... to bad it's not road legal around here)
you still have the yoshi plug in the back of your K4?
have you tried messing with it, does it do anything with the TRS installed?
