i had good spark and had it running. my throttle cable was sticking open. so i pulled out the end at the carb with the slide and cleaned it real good.(took the seat off to do this). the throttle cable was still sticking so i took off the throttle grip which required loosening and wedging apart the upper and lower halves of the kill/switch and headlight switch assembly.i cleaned the throttle twist assembly and greased it so it moves properly. put it back together and i have no spark. is it likely i disturbed something under the tank, thereby losing a ground? the headlight switch assembly is attached to a wire that runs through the handlebars. that wire is barely long enough to make it to the switch, so it was stretched a little as i wedged it open. since the kill switch is in there,too, maybe i lost a connection in there? any help is much appreciated, thanks.
