Carb it's self is great. However, J&P needs to note in their "Direct fit" look up, though this will "fit" a Ultra, there is no option for connecting cruise control. That is a major problem. Primo is no longer producing an adapter either. Mikuni would be wise to address this too.

By far the easiest carburetor to tune and get running perfect right out of the box. Huge upgrade from the Harley CV carb. Great throttle response! Definitely would buy again.

Awesome carb. Runs perfect right out of the box. My bike never ran this good. The stock fuel line (1/4”) did not fit over the mikuni inlet. Had to buy new fuel line (5/16”) but it was good to replace the old line anyway.

This is the carb I put on my 2006 Harley Sportster 1200 Low. I really like it! The carb looked great and came with 2 helpful manuals plus 2 different sizes of main jets out of the box. The bad thing was there was a few missing parts I needed and I had to get them from the dealership. Anyway, with the missing parts bought, I was able to put the carb on the bike in one afternoon. I was able to use the stock chrome throttle cables and made sure all of the cables didn't bind up. The instructions were confusing about the vacuum hose fittings but when I figured that out, the bike fired right up on the first try. I made some minor tweaks with the mixture screw and I put in the larger main jet to be sure the carb wouldn't run lean. I took it for a test ride & it sure pulled like a freight train! Later on I pulled off the stock air cleaner and mounted on an Arlen Ness Big Sucker. It mounts easy on the Mikuni carb using the same adapter ring. Don't settle for the stock CV Carburetor that can overheat & ruin the engine like mine.

Solved my recent chugging problem with my old CV carb. Seems to have more zip too.
