Not me, the bike. It's a V-Star 650 Custom, 2001, with a V&H Cruzer exhaust (plus Smart Partz baffles wrapped in stove rope) and I've disconnected the AIS. Otherwise, there aren't any other mods. Until earlier this week, nary a puff came from the pipes. At idle I get a wisp of smoke from the front pipe, the same under power, and blows a large but faintly-colored blue cloud from both pipes when I roll off. It also pops once or twice almost like a backfire every now and then. The smoke shows up regardless of engine temp, and smells a little like gas. The bike starts on full choke, which I quickly reduce down to about half. I can ride at that choke setting until it warms up (a few minutes), then shut the choke and she'll go like a rabbit. There's about a gallon of two month old gas in the tank with a half can of Seafoam in it. I pulled the plugs and compared them to an online chart (here). They've got a little oil fouling, but nothing else. The plugs have less than 50 miles on 'em. So what have I done? In the past three weeks I've done some parking lot wobbling, shot Dri-Slide on the throttle cables, and today I cleaned the jets in both carbs. The pilot jets were just a touch gunked, while the mains were clear. Gas is a pale yellow, and has the usual reek of ethanol mix. The AIS has been disabled for quite a while, because it sounded like a popcorn machine every time I rolled off the throttle. Dri-Slide did drip from the carb face on to the front intake tappet cover. The intake boots are tight with no cracks, and the tappet O-rings are new. Either the Dri-Slide got inside the carb by running down the throttle shaft, or something else is going on... ... I just wish I knew what.
