Off Idle Bog...Not TORS

I rode my first 100 miles on Saturday and noticed a little idle hang when pulling up to intersections, so I decided to pull the carbs and give them a cleaning. (last time was mid season last year). The sled was running perfect except for the slight hang.

Everything looked real good with no restrictions, but I cleaned everything anyway. First time to pull the floats and clean the little screen on the needle and seat assembly, did find a little crap on it. Set the fuel screws to 2 turns to see if it would help the hang, re-assembled everything and fired it up.

Serious bog off idle to WOT. So I tried it a couple of times and decided to pull the carbs again and reset the fuel screws back to 1 7/8 turns. Re-assembled and the bog is still there. Called it a night and researched today.

Looks like the TORS, for real? I know it's an easy test, which I tried tonight. Not it. Is there anything else I should check? What about fuel in the vent lines? I know when I had the rack upside down, the lines filled with fuel. I am going to see if they drained back into the bowls, if not maybe a little air to push it there.

I would like to get it straightend out, cleaning the carbs isn't bad, just the after math! Thanks in advance for the advice!

Hey Guys,
Not sure about the answer to the questions unless float level off?? but I am interested in the whole fuel in the vent lines thing. My Viper seems to run good. Fuel screws are 2 turns out but like axapowell, I have fuel in my lines as well. Normal? I'll do a search right now, probably find an answer there. BTW, this site rocks and rather addicting to say the least. All you guys are awesome and the knowledge you guys bring to the table is very educational.
 
Why are your fuel screws turned out so much guys? It would cure idle hang but would be fouling plugs will idleing/warming up. Mine I think are at 1-1/8.
 
Viper...1 7/8 turns. Just went out to the garage. There was still fuel in the vent lines. With the engine off, I cracked the throttle 1/4 open and lightly blew into the lines to clear them. Tried to start after and it was flooded. Cleared the flood, and the bog seems better, but until I ride again, I won't know. Just afraid that I screwed something up during the cleaning. Don't really want a melt down.

I do have a second rack of carbs that I could bolt on and try with the exact same stock set-up that I have. Just am looking for an answer why this happened...

My best guess is a pilot jet still has some blockage in it. You have to look through them and see a nice, round hole to ensure they are clean. If you're an old hand at cleaning carbs, then I apologize, lol...
Also, make sure the boots are all on correctly and one didn't fold under on the bottom. I doubt it though, since it was bogging before you cleaned them.

It was running perfect before I cleaned them. No bog, just a slight hang. Pilots are perfect. No blockage. I've done this before with NO issues, so just looking for a reason.
 
I think you need to figure out if it is a lean bog or a fat bog. If you blip the choke then hit the gas does it hang? Do you have an air leak somehow after putting everything back together?
