Not running right after rejetting

I have an 01 883 that i recently pulled the carb and adjusted the idle screw along with changing the main jet. The main jet was originally a 160 and i put a 165 on the carb. I also put a washer on the needle per dealer recommendation. I put everything back together and bike started and idled fine, but when i tried to take off immediately lost all power and bike stalled out. I then tore everything back apart and removed the washer, but left the 165 main jet. Now that i have everything back together again bike starts and idles fine as before, but if i roll the throttle all the way on the bike stalls right out. The pilot jet is a 45. Thanks for all help.

If the main jet is clear, nothing blocking it, make sure you have not pinched the diaphragm and there are not any pin holes in it.

Main jet is fine. Diaphragm is the rubber boot attached to the piston correct?

I had a similar issue with my 96' Hugger. I would roll of the throttle and I would get a real bad hesitation and it would almost stall. I found that my acceleration pump was sticking. Just something to consider.

If the diaphragm is not installed correctly it a problem. I have a link where the guy says never mess with the top of the CV carb because it's really hard to get the diaphragm seated correctly again. I just replaced my slide needle and I'm having the same problem, my bike starts fine and just normal shifting is fine, but when I "get on it full throttle" the bike stalls out and I have to let off. This guy also recommends not replacing the slider needel or the original spring, so I'm going to reinstall the diaphragm and the original slider needel and the spring. I also read the to keep the diaphram in the groove apply a small amount of vaseline in the grove and that will help keep it in. I have a 1997 Harley Dyna Low Rider, but it has the same carb.

Let me just clarify what is going on...bike will start and idle fine. I can feather the throttle fine but as soon as i roll and hold it on 1/4 - 1/2 - full - the bike starts to stall out. I cant even attempt to ride the bike it stalls out in 1st gear. Just gonna wait for more posts before i attempt next fix.

I guess I have the question of this? Why did you pull the carb and rejet in the first place? Did you up grade your exhaust and air intake? Did you upgrade just one? Is the engine stock or have you done mods on the engine? These things all have a bearing on how you set your bike up? How do you ride your bike?

Just 1 ? - Do you have the HD manual for your bike? - Pull the carb and check out the acc. pump when you come off idle and crap out it sounds like you may be having a issue with the pump.
Look in the manual for a pic of the carb and make sure everything is in place.

Reason for rejetting was that i was experiencing the carb farts from the bike, after looking at some things online found that is most likely caused by the idle mixture, but since i was pulling the carb i figured i would check out the jets and see if they were what is recomended for my screamin eagle exhaust/intake setup and the main was 160 when the recomended setup was 165 so when i went to the dealer they gave me that and also told me about putting the washer on so i did that as well. Also i do have the manual and i will look into the acc pump issue, im guessing the best way to see if this is sticking is to pull the aircleaner off and roll the throttle on and see if the acc pump continues to shoot fuel?

I took everything apart and put the original 160 jet back on and still the same issue, so obviously some issue with something being messed up or not put together properly. I also reseated the diaphram(vacuum piston) with the tip of using vasoline and still the same thing, so then ran the bike with the cleaner cover off to make sure the acc pump was not sticking and no sticking, but i did notice that when i rolled the throttle full on the vacuum piston did not slide the whole way up it went about half way and that is when the engine started to stall out. Im guessing there may be an issue with this part?

After looking around on posts found one that said about putting the needle jet in backwards...checked that and that was the issue...thanks for all help

I'm having the same problem, how do you know you put the slide needle in backwards? What do I look for?

Thanks
Jack

How do I know if I put the slide in backwards?

The small hole on the bottom has to be on the inside or closest to the throttle plate.
#4 Vacuum port

When I look through the throttle plate I see a small dimple that looks like its been drilled very lightly with a drill bit.on the slider..does that mean the slider is installed ok??

You're a great dancer...LOL

Thanks for the help

I rejetted my 2005 Softail, everything ran great but sometime it would backfire through the carb. With a little fine tuning it runs great. Just have to find the right settings.

I've only had one CV carb that I ever worked on. That's because I just switched from fuel injection to carb. But I think there is a dimple on the outside of the slider, but I don't know if they are all like that. It would be best to go by the drilled hole and remember, don't make that hole any bigger. I learned from the smarter guys on this website that larger is not always better.

I'll keep dancing...... it's all I got left
