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??
