Default 04 XL cutting out when warm

Howdy folks first attempt at posting here. I been a lurker since I joined and I have to say, the knowledge in this forum has helped me cure quite a few issues with my bikes, many thanks to all.
Ok first the bike and stats, then the issue. 2004 xl883 pretty much factory. Upgraded air filter, and put V&H short shots, louder the better, right haha. Removed and upjetted the cv carb one size on both jets. Replace ims with thumb screw as always. Accelerator pump diaphragm ripped, so replaced that. Cleaned the entire carb with air and cleaner when it was apart, as always. Put it back on the bike and tuned the ims. Found the sweet spot without touching the idle speed screw. Let it sit on the lift and idle for roughly 15 minutes.
Now heres were the kicker starts. Start to roll the throttle and it begins to loose power. Give it a little more and it wants to die. Let off the throttle and i get puffs of gas smoke out the pipes. Do it again, same thing. Use the gas torch trick and wd40 spray trick around, and no difference. Adjust the ims out to 4 turns and it makes a little difference at idle, but still wants to die when slowly rolling the throttle. Newest XL I've worked on was my 00 1200 xlc. 04 has a few more wires, but the cv carb is the same. Any direction pointed would be as appreciated as before.

If you haven't had a welcome before.Welcome!

Have a read here.........http://sportsterpedia.com/doku.php/techtalk:evo:carb02

You should hopefully find some answers.
Try removing the air filter and make sure your slide is working would be my first thought.
Good luck sorting your problem.

Did the jet sizes need to be increased? Do you have the needle jet the right way up? Exhaust leak?

I'd have to go with Folkie on the needle jet being in the wrong way. It's easy to put in the wrong way.

Thanks for the replies fellas. Yep big end of needle jet up as always, put big end down once and chased ghosts for a few weeks. When I go more air and open pipes I found going from factory 42 to 45 and 165 to 175 is a pretty good starting point. From there maybe go down to 44. I was just wondering about possible electrical issues. Maybe crank positioning sensor, or coil problems? Problem only happens when the bikes up to temp. And since my 2000 xlc has no cranks sensor. Electrical is definitely my week point.

Folkie, how would an exhaust leak make it act like it does when it gets warm? Thats one I haven't run into yet, but I'm always willing to learn new info.

Here's the Sportsterpedia secton on Testing Coils:
http://sportsterpedia.com/doku.php/t...n_coil_testing

and the Sensor page:
http://sportsterpedia.com/doku.php/t...k:evo:engctl03

You may want to remove & clean the CKP sensor before testing...

It's similar to having an intake leak. You need to adjust the mixture rich (choice of jet and/or adjusting the idle mixture needle) to get it tor run nicely at idle, but then when opening the throttle, it bogs down.

It's less of a problem when cold, because you need a richer mixture when cold (which is why you have the enrichener).

"Let off the throttle and i get puffs of gas smoke out the pipes.": could fit with the problem being an intake or exhaust leak and a fat mixture.

BTW, your original post itself doesn't mention it happening only when warm. You describe tuning the idle mixture; obviously you'd have the bike warm when doing that. What happens when the bike is cold?

Thanks IXL for that link, I added that to my home screen on the garage computer, that one looks like it could be my new "go to" link. I'm gonna clean it first thing.
Folkie, ok I'm following you so far, I never knew an exhaust leak would have the same effect as an intake leak. Now will the propane torch or wd40 trick work on that leak same as an intake leak? Or is there another way to find out? Yep it only puffs the smoke and starves for power when warm. Sorry I didn't mention that specifically before, it might have helped. Cold bike, I pull the choke and it fires right up and idles with choke all the way out. As it warms up I push the choke in and i can still roll the throttle and it's got the power. When it's up to temp, about 15 to 20 minutes and the chokes all the way in, that's when the issue starts. BTW, I did try to go back to original jets and it still has the same issue.

Put a teaspoonful of engine oil in each spark plug hole, start it up, and see where the smoke comes out.

It's so easy to do, that it's not worth not doing it, even if an exhaust leak seems unlikely.
Intake And Exhaust Leaks Tests
Mick says to put a ½ ounce of oil in each cylinder. I found that to be a bit too much (the smoke seems to go on forever); I think about a teaspoonful in each cylinder is enough.

It's not always where we think it is - So here's another Sportsterpedia section:

When you're having issues with the electrical system, use this Sportsterpedia section about
checking the battery cables, voltages and grounds - DO THIS BEFORE ANYTHING ELSE:
