Hi and welcome..
Posting a kart ID?
simple just upload the images, ideally the mfg straight ons (like in the FIA documents) too
together with the info you got
detailed description on how to post pics
Asking for an ID is the exact same,
but you should post some good detailed pics of your kart chassis instead
(not the mfgs chassis images) and chassis, so with as little bodywork and fairing as possible.
best shots are indeed taken without any plastic part and straight from above
(no side pods, no nassau panel, no tank, no seat, no front bumper)
OR which is far less complicated:
just get a few overall shots of the chassis (still the plastic is the least interesting for ID'ing),
post the homologation number and all details you have;
and when in doubt we might ask for more images of a specific region.
No there's no simplified version for smartphones;
we have a tapatalk plugin installed however,
so if you use the tapatalk app,
the forum will be differently rendered for you within.
Upload then is a pain however (tapatalk is no longer as good as it was a few years ago IMHO)
