04 Vegas running rich

I cleaned the throttle body, and replaced plugs. I have been having some starting issues so I got new plugs again, and swapped them to eliminate that issue. The plugs were fairly black after about 5 days, so it seems the bike is running rich.

I have the stage 1 map, and ness swept exhaust, there are also holes drilled in the front of the airbox. (everything was done when I bought it). Everything I am reading these bikes run lean from the factory, so what could be causing the rich conditions?

first how long do you leave enrichener on or or some call it chock. You might be leaving it on to long.
go to dealer and have them reset you throttle body sensor

don't know where your buying your plugs from but auto parts stores sell them ask for NGK 3481 it will be cheaper then dealer

Depends how cold it is, but usually turn it off right away. If it's cold out, I turn it down and let it run until I hear it idle up. 30 sec to a min. I got ngk's from advance auto. Dealer wants me to leave it for 2 weeks until they can get to it. There's a couple others that aren't too fat I'm going to check with too

The bike doesn't have an enricher the lever on the handlebar it's a throttle bump that only raises idle speed for warm up. My 2004 Vegas was running pig rich and I had to take it to the dealer to use his Vic software to reset the TPS (throttle position sensor) The home brew TPS reset never did squat for my bike. After the TPS reset at the dealer it ran perfect.

I had the same problem and that was my only fix he charged me one hour shop rate.

2015 Cross Country I use corn fed gas, 89 octane and Rotella oil. How's this thing still running?

Yea I tried the reset sequence, no go. The dealer said they would charge for an hour as well. Just don't want to leave it there for 2 weeks.

I had the same problem with my old Kingpin. I had the same experience as Vindex1963.
Also, when I built the motor in my Kingpin up, I took it to a local tuner who Dyno tuned it and adjusted the TPS for the new configuration. The TPS is adjusted with resistance. Using an ohm meter I believe. You may be able to get the specs through a little research and adjust it yourself. I'm not sure though, I haven't done this myself.

Well, I think I fixed part of the problem. I found an old thread that recommended pulling the starter button apart, and cleaning that out. There was some corrosion on the connections. Seems to be starting a lot better now.

I have not yet, still seems like I may need to. My dealer is only open late 1 day a week so I haven't had a chance to get it up there yet.
