Thanks guys, that’s the info I was looking for. I suspected it was running way rich on the bottom end and then once it got past the point where that circuit was having a large effect, in my case, about 3k rpm, it got back to a reasonable AFR and ran clean. Well, I bought the bike knowing it needed a carb rebuild so overall it’s not a huge deal but now the picture is much more clear as to why the bike was sitting. I understood, or they knowingly let me believe at least, that they just stopped riding it for personal reasons and it sat until they were moving to Chicago and didn’t want to take it with. They conveniently forgot the part about it running like crap prior to parking and not being able to fix it. My first inkling something was wonky was the idle air screws being turned nearly all the way in (like, 1/8 turn from bottomed out). Oh well, in the end not a huge deal. Thanks again for the info!
