Ok, so i was trading i mechanic i know tattoo work for doing my carbs. hes worked on it before with no problems. this time, when i get it back, next day the air cleaner box falls off. i fix it. next week, fuel pump is hanging under bike, mount gone. i zip-tie it back in place, but it seems to be missing a screw from the center of the end opposite the fuel lines... so bike begins to die after running about a block or 2, each time its started cold; after a few min, it would start again and run ok. then, it decided it wouldnt: it will start and idle fine, sometimes rev with the throttle, if in neutral. if its in gear (and sometimes if in neutral), the engine dies as soon as i give it any throttle. choke seems to make no difference. i checked the plugs, and 2 of em had been replaced with generic auto plugs- and one of those still had the little threaded sleeve on the back, so the plug-wire was just resting on the plug! changed em all, to no avail. can anyone help? i need my bike for work!
