i have a 96 b6 it has just over 9k on it. it has new plugs and wires. when you first start to ride it after i let it warm up for a while it has this killer dead spot between 1k to 2k rpm it spits and wants to die. its stock except a scorpion pipe . the pipe tie is turning black meaning its rich and you can smell gas when you first stat it. but the plugs look great they have 1k on them i dont know where to start looking . thanks

Mines been like that for 12 years now. Funny thing I was just thinking about fixing that too. I just sync'ed my carbs and noted that there was no way to make it run between 1500 and 2000rpm . It just jumps from 1500 to 2000rpm. It really seams bad when going real slow and making a turn between those rpm. I was thinking maybe the pilot jets may be clugged or maybe my starter circuit is stuck open just a tiny bit. I'm planning to clean my carbs real good and see if that helps. Right now I don't have time and don't know when I'll get to it. I'm going to get some seafoam and see if I can hold off on the real cleaning. I was looking at my starter cable and it looks like its a hair to short, I remember it being like that when I bought it and put it on years ago. I needed a cable and just went with it. I was looking at the parts fiche today and it has three starter cables and I'm bumb founded. Don't know what part # to order.

96 B6
HoleShot 17" can
K&N air filter
V&H 5 deg. advance
#100 main jets in all four carbs
2 Radio Shack shims on the needles
air/fuel screws 4 turns out right now

Make sure the starting enricher (choke) is completely closing. Then adjust the air screws. Sounds like you could be rich at idle. Maybe turn the air screws IN 1/4-1/2 turn.

Do you have a clean air filter?

Hmmmmm? I put a D&D pipe on, holeshot jet kit and the ignition advancer. It had a dead spot just above idle. I got used to it eventually. Then, this spring I cut about 6" off the D&D can and it actually runs much better now. I don't know why but it looks cooler too. I guess it was rich and this leaned it out a bit maybe. It could be too rich. Carbs can be frustrating sometimes.
