Ok normally I would do a search but with the mods not trusting what I may find and don't really want to chase my tail. So here's the story:

I have a 2000 V92sc and she is acting up. When she was built she ran a little rough so she paid a visit to the local Vic dealer. Only engine mods were to the exhaust and that was a different set of Vic pipes (Slip ons see pic below). The mechanic attempted to dial her in and smoothed her out some but still not quite right. Comment was two options one a new computer or get a Wiseco Fuel controller. Wiseco controller was the direction taken. Flash forward 3 years and I decide to pull the air box and punch out the 1st set of baffles. At first all ran great with no issues but lately I have had 3 issues as follows:

Pulling out of a driveway and jumped on it, went thru the gears real fast. Made it to 4th or 5th and she bucked a few times then died. Pulled over and she restarted fine and all went great for the rest of the ride.

Few month later was cruising home and downshifted to pass a slow moving car. Missed a gear and all of a sudden she is bucking, farting and loosing power. Made it around the car pulled in the clutch and she snapped out of it.

Few more miles down the road passed another slow mover and same thing but this time she died. Guy in truck pulling a trailer pulled over to see if he could help. He got to me and asked if I ran out of fuel (Nope) I hit the starter and she fired up. This was somewhat embarrassing as the truck/trailer was from the local Harley shop and he was delivering a bike. :(

Took her to work today and ride in was fine. Ride back however wasn't. Crossing a bridge she just died. I wasn't jumping on it, didn't miss a shift was only rolling along at maybe 10 or 15 mph max. This time she wouldn't start. Had to push her across the bridge to the center island all the way trying to restart her. She would turn over but not catch. Waited a few more minutes (A good ten has now passed) then tried again. She finally caught after turning quite a few times and the rest of the ride home was fine.

My initial thinking is I need to adjust the controller to dump in more fuel because of the latest changes during cruising and full throttle. What do you guys think?

I think that probably the fastest way to figure it out is to find a local guy with a dyno and pay him to run it and check to see if your air fuel ratios are far enough off to cause a problem. Then go from there. Chances are you are lean.
Most places will run a bike and give you a print out of the air fuel ratios for a rather minimal fee. It is when they begin to change things that it gets more expensive. However you need to leave with a printout of your air fuel ratios or you won't know what to change in your fuel controller.

It could also be that the bike originally had a sensor that wasn't right or something intermittent. That was the reason for needing the Wiseco fuel adder and it has finally gotten bad enough to be contributing to the problem in addition to your being lean after doing the intake mods. It could be something like a coil that goes open when hot. Something not properly plugged in that gets hot and goes open etc. It would be faster and probably cheaper to get the Afr right or close enough that it isn't a contributing factor and see if you still have a problem. Then go from there.

Actually Joe_ that's a good idea. Now the trick if finding one. I think the local Harley shop is the only place around me.

can you post your fuel setting
Stock was:
G 4.5, Y 1.5, R 6.5, B-G 5.5, BY 4 and B-R 4

Setting after bike was built was:
G 5.5, Y 2.5, R 6.5, B-G 5.5, BY 4 and B-R 4

I figured it needed more fuel so I just changed it up to:
G 5.5, Y 3, R 7, B-G 5.5, BY 4 and B-R 4

But have not taken it out for a test ride yet

G is for Idle/Cruise

Y is for normal acceleration

R is for wide open throttle

Not stupid. Sometimes the simple things are the answer. I'll check it out.

And thanks for the compliment.

Swap your fuel pump relay with your headlight relay. It has nothing to do with tune, but your relays are getting old
And this is why we join forums. I'll give it a shot.

Something simple to try....

Take the 2 fuel filters from the "snorkel" pipes at the rear of the tank. Clean them. Run a little gas through some tubing from them into a bucket to flush solids.

Also, look between the "V" on the right side of bike. Rubber plug/cap on vacuum line. It'll be cracked. Take it off and go by auto parts store and pick up assortment blister pack of rubber caps. Find one that fits. Rub a little hi-temp silicone on the nipple and slide it on.

Between what Kevin suggested and these, it'll probably fix it.
