Review: Extremely great value. - You can’t beat these copycat carb. Can’t tell the difference from the stock Harley CV 40 carb and the Harley carb has a plastic hose Nicole whereas this one has a brass one. I used it on my 04 Sportster and it runs great. Had to adjust the idle mixture screw and it is spot on and also put in a #48 pilot jet and runs great. No different than you would had to have done with the higher priced ones.
Review: For what you payed, can't beat it. - I was contemplating 3 stars or 5 stars, but settled with 5. I have a 2006 Harley Sportster 1200 Custom. This carb fit perfectly, no issues with that, the bike runs great and I'd certainly recommend buying the carburetor. That being said, I did need to cannibalize a few parts from the old carb, mainly around the throttle cable area. The plate for idle screw had to be bent so the screw would touch it. Had to swap out the new spring for the old spring and a plunger (?) which would be parts 31 and 33. Now, the diagram shows part 25 which I didn't see on the new carb because part 31 wasn't inserted where it should've been, so could've fallen out some point. Instead of using the old spring and plunger, I could've just used a small washer if available, I settled with swapping in the old parts. She fired up beautifully! You could spend $400 on a new carb from Harley, or wherever. Or you could spend less than $50 bucks on desertcart, spend a little time tweaking things into place, and have a great running bike. I'll save the old carb for parts, likely rebuild it later on. BTW, I didn't need to adjust the air/fuel screw. They've got it cranked 2.5 turns out which had the bike running beautifully. You will need to adjust the idle screw once you get the new carb in place... especially if you need to bend things into alignment. Happy customer here.

### ⭐⭐⭐⭐⭐ Works perfectly like the original carb used to on my 1992 Softail. Unbelievable value!!
*by S***R on July 21, 2025*

I bought this carburetor to replace my original carb on my 1992 Heritage Softail thai I bought new back in 1992. I was reluctant to replace my original Harley Carb with a Chinese knock-off, but I needed to get the bike running fast and I didn't feel like rebuilding my old carb again. I was totally amazed with the end result. After installing this carb, which fit perfectly, the bike started right up and ran as well as it ever has in my 33 years of ownership. While I was skeptical at first, because the slider didn't feel as smooth as the stock one, and past experiences with chinese parts has been lackluster, the bike fired into life and ran like new. What's more amazing to me is the price. An original harley carb is about $800. This one was $43, came with fuel filters, fuel line, cleaners and even two spark plugs. I don't know how they build and sell such a decent product at this crazy price point, but it was cheaper to replace the carb than for me to rebuild the old one. I've only run a single tank of gas through it so far, so i can't tell you about the long term reliability, but the first tank of gas has been flawless. While I was relucted to "taint" this 'American' bike with cheap, foreign parts, I have zero regrets. If this carb stays reliable over time, this will be a total win!
