    200s vavle specs.

    I recently bought an 85 200s for $150, the guy took the pull start apart, and wasn't too smuckin fart. I got it home, un-did what the previous owner did, cleaned the carb up, put some new rubber on it, fist pull, running like a maniac, but sat for awhile and the valves are a bit out of wack.

    i think the specs are .003 intake, and .005 exhaust, but im not sure.

    I called the local honda cycle/atv shop, THEY ASKED ME WHAT A 200S WAS, AND IF IT WAS HONDA!!!!!

    Then told me not to waste my time, they wont touch anything older than 1990. Jerks

    does anyone one know these specs for sure??
    If you can't fix it with a , its an electrical problem.

    85 ATC 200s--Ratted out and not running at the moment

    86 ATC 200x--All stock other than the handle bars

    85 ATC 250es Big Red -- Just got new rubbers and she wants to ride!!

    04 Suzuki LTZ250 quadsport - It was a decent price and I'm a raging idiot.

    well ive got plenty of time to do it now, i was doing a doughnut, and the tires found a hard spot, instant 12 oclock, well more like 10:30 wheelie lol, bent the stock handles a bit, so i got lucky at the local shop, they had one pair of MSR bars, for 20 bucks, i put them on, made a mixture adjustment on the carb, and the thing never ran so good, throttle cable snapped after a few hours, and i got towed home, the guy that was towing me got me half in a rut, and let the rope slack, then jerked it tight again, ass over teacup i went, dragged me upside down for a about 5 feet, and bent the new ones ever so slightly ON THE FIRST TIME I WENT RIDING WITH THEM ON!

    they arent bent badly though, just slightly, so now im waiting on ebay, so far im paying $1.50 for a new carb, cable and throttle assembly, but im sure that price will go up in the 4 days that are left, seeing as i cant ride might as well get those feeler gauges out, thanks again for the help, now i gotta go find what the hell i did with my motivation, lol
