Well that doesn't narrow things down very much! It's a 125.. is it a bike some-one has converted to a super-moto? Is it some obscure make that's badged the model as a super-moto? Help us help you a bit here!!! A BIT more precicely, WHAT is t, Make, Model, Year!.. does it have a umber-plate? Log book should gve the details needed!

Well, THERE is a good place to start. Do you have a workshop manual for the thing? When you started taking the most intricate and senstive bit of the bke to bits? When you put it back together, did you use new gaskets and seals? Did you set the needle, float, mixture screws to the settings in the book? Or just twiddle randomly?
If you disturbed gaskets, didn't clean faces or use new gaskets seals, then Y-e-r-s... GOOD change it's sucking too much air through the gaps! If you randomly twiddled mixture settngs, stuck the needle back in on whatever slot you guessed at, YUP, some very very good reasons the thing might misbehave.

Begging suggestion you didn't take the battery OFF the bike to charge it off the car.... therfore good change that the HUGE amps banged out by the car generator, at maybe 50% more volts, gave the bike's regulator a heart attack, and fried it....
[quote="supermotogreener125"]I took it for a ride and literally 300 yards down the road it did the exact same thing it did to begin with. I sat with it for around half an hour and it rough idled and didn't want to move. if I touch the throttle the slightest it will just die out./quote]
SO, whatever you have done... probably wasn't the real problem.....
Start from scratch; get the book; base line the issues; eliminate the obvious first by doing a FULL basic service; change the plug, check the plug cap/lead, if 4T check tappet clearances; if OHC check cam-chain tension; change the oil; check & clean air-filter; check the exghaust for holes, lost gasgets etc; REVISIT the carburettor! Undo whatever you hav done; put twiddle screws back to book settings, re-assemble with nice new seals and gaskets!!! Check the fuel hose; check the fuel tap; has the tap got an integral strainer on the inside? Is it clean and clear? Does the tap 'flow' fuel? Is it a vacuum operated tap? Check vac hose from manifold.... if fiddling with carb have you yanked the vac hose off, or split it shoving it back on, stopping it turn the petrol 'on'?!
Possibilities are legion;so start at the top, and start working logically rather than randomly; BY (and possibly BUY) the book; and work through the list.
