today i woke up my stella166 and p200s running after sitting for two months (i just got back from vacation in italy)
stella is a little smokey. i got some gas and added 3% oil to the mix, ran it around, but while it started up with little problems, it felt like it was going to die if i slowed down when I ran it around the block. i upped the idle and went for a gas run. after getting gas it seemed to have worked through any bogging concerns.
p200 was more difficult. the carb slide link somehow disconnected from the throttle control arm. (

TravisNJ had this problem a few years back with it disconnecting while he rode, but I'd imagine it was just neighborhood kids fucking around on my bike as it sat on the sidewalk. pumped up the tires on the p2 (i've had a slow leak in my front tubeless for... years now), so I give it some air every month or two anyway.
