ok i have a 86 honda trx 200sx and i bought it a month ago and i rode it for a lil then i replaced the head gaskets and it didnt seem to run as well as before but it wus still good and strong smoked alot and then one day i washed it and it hasnt worked right sence its making me really mad i have spark air fuel and compression ive cleaned the carb also i think the idle screw is messed up a lil but it smoked a good deal wen it ran but the kid i bought it from said he just rebuilt the head but didnt replace the gaskets so im thinking that its ethier the carb or the valves are not sealing right does anyone have any ideas at all im not a big mechanic but i know alotta my stuff and i know these old quads are hard to beat and ussaly run like a chanp
