[SIZE="a"]I have an 04 Vl800X that has really given me very little trouble since it was new. This Spring it needed tires and hadn't had a once over by anyone qualified in a while, so I got the Spring tune-up special at my local (non-Suzuki) dealership. It ran fine getting it there, but ran like crap afterwards, with all of the bogging symptoms described, plus getting it to go over 50 was nearly impossible. It's a long story, but the short of it is that the aftermarket air filter they used was too porous, so the air flow into the carb wasn't drawing enough fuel. The OEM filter fixed most of the problems.
The bike was rideable, but still having some bogging problems at idle, and when gently throttling from idle, occasionally stalling at a stop. Pulling out the choke made it run OK, but of course at higher RPM, and that's no way to run a bike. Adjusted the Pilot jet top to bottom by ¼ turns, which didn't fix the problem. Finally decided to return it to the shop, and locked the choke out about 1½ clicks, figuring I'd just live with it to get where I was going. Hated how fast it was idling, so I tried reducing the idle speed with the adjustment knob, bringing it down to the lub-dub I'm used to. Bike now runs exactly as I'm used to it running.
I'm not sure if I've actually fixed anything, and plan to follow up with my mechanic, but I'm thinking that perhaps in all of the messing around done by both shops, somewhere along the way the choke got messed up.
I'll follow up here when I know what the scoop is.[/SIZE]
