Alpha Rider Pro Carb Rebuild Kit Mixture Screw For Keihin CV CVK Carbs For Harley Big Twin 1990-1999, Twin Cam 1999-2006 & Sportster XL 883 1200 1988-2006

Impressed, used with my Constant velocity Carb..............adjustment is easy to do.

as described, good fit

Edit: sept 9th 2020.... still going strong. Was worth the money...Installed on a 1998 sportster 1200 Custom with the stock CV Heihin carb. Before installing I recommend cleaning the part with brake cleaner before installing as mine had a little chuck of brass and some small brass shavings in the threads from when it was manufactured, just to prevent anything thing foreign from entering and clogging your jets... no big deal you should always thoroughly check and/or clean any part prior to installing. Furthermore they do seem identical and the new one threaded in no problem. I did NOT have any issues with the spring provide as some other reviews said it didn’t fit. The only small thing I saw that could be an issue is the diameter of the very very tip is slightly bigger (like 1000ths?) which may or may not have sealing/seating issues but I’ll update once installed and tinkered with. So far I’d say it’s worth the money, will update if views change. Ride safe🤙

Did eagle Mike upgrades to carburetor working good 4 months on and off road little wiggle but no leaks. 4 stars for the money

Fit Perfectly and works great in a 1998 (Softail) and 2003 (Dyna) CV Carb. Make s adjusting idle mixture so much easier..

You're buying this for added adjustment convenience with the thumb screw head, but it doesn't have the same taper and point of the OEM screw so it won't function identically.In my photo I hold the original OEM adjustment screw, and this product. This product has a significantly duller point. I'm able to screw in the OEM one 13.5 times before it bottoms out, while this product only can go in about 5.5 times. It fundamentally will have different jetting characteristics as the needle point is not identical

Didn't fit properly on a 2005 Sportster XL1200 CV carb Be sure to double check fitment. Be very careful because it does come with small o ring and washer that can easily be dropped and lost.

Worked perfectly on my 2009 Buell Blast!
