Nice find! No your not losing it... I had six of them parked at once in a garage here, although they weren't all mine since some of them were customer projects... LOL
The 200ES is still my favorite model, owned one when i was but a wee little trike myself, now i can't get enough of them when i am actually old enough to buy em and fix em.
Quick question... What model Yuasa battery are you putting in these? The battery in my 200ES daily driver is going weak again, really ticking me off actually. Some days it will start just fine, some days i have to use the decomp and listen to it slowly crank away. I know its the battery once again because i hook up my jump pack and everything is right as rain again. I'm about to mount a battery box on the rack and toss in a real battery. I swear all the brands of ATV batteries down here in the states are crap and made by the same company. The battery in there now is a AGM battery that i raved about for nearly a year, really good performer, then this spring it just started going to crap, takes a full charge with the motor running most of the day doing jobs with it, and the battery maintainer will say its fine after about 20 mins of plugging it in, but put a load tester on it and it falls flat on its arse... Ugh
