V Star 1100 problems

I just installed a kuryakyn pro r hypercharger and rejetted the carbs on my 2001 v star 1100, I put a 125 main jet in the front carb and a 122.5 main in the back, according to the instructions I was supposed to lightly set the air to fuel mixture screw all the way down and then back it off two full turns, well I followed to instructions and I got a whole lot of popping and backfiring when I rode it. I took it all apart again and back out the atf screws another 3/4 of a turn and it got rid of the popping and backfiring, the only problem I have now is that it feels like it wants to die out at high rpms now. it does it in all gears at the higher rpms

I wanted to see if anyone here has had the same problem or if anyone here has a hypercharger?

do yall think I might need to back out the atf screws a little more? maybe its not getting enough fuel at the higher rpms?? I don't know, im a decent mechanic but not great, any tips?

I suggest that you check the couplers. I had similar problems when I installed mine and found that one of the couplers was blocked due to a casting defect. When reemed it out it immediately ran fine. As an aside: Periodically check the vacuum line to ensure that it remains attached as it has a tendency to come off in time. Also, I had to replace the diaphram at less than 30,000 miles. I initially thought that the butterflies were merely cosmetic, but after some reflection and discussion with others I concluded that if they were always completely open the bike would run too lean at all but full throttle. Hope this helps.

I installed the hypercharger-pro. Had the same issues. Re-jetted to 150 front and rear, removed the air box and installed the pods. I have the Cobra exhaust full system and the bike runs like a raped ape.

Do you think I could just put in 150s with the charger and air box or do you think the pods are a must for the setup your talking about?

Not with that Hyper Charger on there....150's are way too big. You need to follow the jetting instructions that came with it exactly....

Exactly what throttle position is it that you have the issue with. Have you tried turning the choke on slightly when it happens to see if the issue gets better or worse? That'll tell you if your rich or lean.

Man I don't know anymore, I just went out and rode and it feels like it's just the rev limiter, but it just doesn't seem right to me, it doesn't do it at any particular throttle position, just at high rpms. I ran it wide open today and the rev limits kicked in at 1st 30mph, 2nd 40mph, and 3rd 65mph I didnt get a chance to do 4th or 5th because I was in a 55mph speed zone, but the other day it seemed like the rev limiter was kicking in at about 80-85 in 5th when I was trying to pass a truck ( not a good feeling to have your bike feel like it's losing power when your trying to pass someone) i never had that problem before the hypercharger/rejet and 80-85 seems extremely slow for the rev limiter to be kicking in, any thoughts??

I don't go by what people think. I go with what works. My bike did exactly what yours did. I went to bike shops, the V-star forum and experimented. I've been running with 150's for several years and no problem. I probably did something wrong.
