perfect, thank you..
see now I know the tank is not to be looked at for reference.. it's one of those chinese tanks
that shipped with ebay 80cc bike-kits
it never belonged to any specific mini bike (not even any generic mini bike I can think of)
front wheel is puzzling me, rear wheel looks more familiar
it reminds me of those 49cc choppers that came with a fake V-Twin plastic engine
...
also chinese sold under different brands in several iterations (one name was vulcan, another Predator)
one of such:
http://www.minipocketrockets.com/predator-mini-choppers/
and another:
http://www.choppers.com/mini-choppers.asp
etc.pp.
here's a link to a road legal 110cc version of pretty much the same thing:

Anyways, that's the exact rear rim (and assuming from that .. the same rear wheel size)
sooo
since yours and that also share the rear frame geometry;
I'm fairly certain whatever fits the predator/vulcan/chopperIII up there
will fit yours.
And with that seat and rear fender are covered ...
front fender is much easier: "pick ANY based on wheel size and you'll be good!"
for parts you might get lucky on
scooterparts4less.com
the "FS517 49cc Super Chopper"
is again that thing from above.. a very close sibling of yours at least.
They do have the seat and the tank (actually two different ones *shrugs*)
and the front fender is at least listed (just not available)
try your luck on the internet searching for "49cc mini chopper"
followed by whatever part you are still looking for..
best of luck!
