Review on Enhance Your Harley's Performance with the Alpha Rider Pro Carb Rebuild Kit and Mixture Screw: Compatible with Keihin CV CVK Carbs for Harley Big Twin 1990-1999, Twin Cam 1999-2006 & Sportster XL 883 1200 1988-2006 by Calvin Reynolds

Edit: September 9, 2020. Well worth the money. Equipped with a 1998 Sportster 1200 Custom with a stock CV Heihin carburetor. Before installing I recommend cleaning the part with brake cleaner prior to installation as I have had a small brass cartridge and some brass shavings in the threads since manufacture just to keep debris from getting in and clogging your injectors. No big deal, you should always inspect and/or clean each part thoroughly before installation. Also, they appear to be identical and the new one screws in with no problem. I had NO issues with the nib as some of the other reviews said it didn't fit. The only small thing I've seen that might be an issue is the diameter of the tip itself, which is slightly larger (like a 1000?) which may or may not have sealing/fitting issues, but I'll fix that after that Update installation and work. While I'd say it's worth the money, I'll update if opinion changes. Drive safe🤙
