Carburetor replacement/ upgrade

[RanchStar]

Hey fellas/lady fellas. I have an 03 roadstar 1600 and have been dealing with non stop carb issues and none can figure out the issue. Bike runs on choke but not off it. And chokes out and tries to die past quarter throttle. Anyways looking for input for what would be a good replacement or upgrade carb for this bike. Dying to get it on the road in good running order.

What’s the bike history? When did it last run well? How long has it been sitting? Probably just needs a good cleaning or rebuild.

It's been rebuilt back to factory. Was running fine then previous owner had shop jet it for higher altitude riding and hasn't ran the same since. I have rebuilt to factory. Adjusted float hight to 4mm as per the tech bullitan. Replace choke assembly. And fuel mixture screw is 2.5 turns out per specs. Still runs bad

You’ve got this posted in the wrong place. Few will see it. Needs to be in technical forum.

Bingo! You had the shop rejet it. They rarely know what they are doing with these bikes. You need to repost in the Technical portion of this site with your current jetting, intake air filter and exhaust setup. Folks won’t see this since you posted it in the For Sale section. Carburator riders here will then tell you how to adjust and possibly rejet. I have a fuelie.
