Tuning or rebuilding the carb on your classic Honda CX500? This set includes two main jets – sizes #90 and #120 – perfect for the 1978-1982 CX500, CX500C, and CX500D models. The brand is Damineding, and these jets are made in Taiwan, known for decent aftermarket motorcycle parts. They come brand new in original packaging (might be a simple bag or box). The manufacturer part number is MJ90-120. The seller offers a warranty (check details), but there's no UPC. Main jets are crucial for getting your fuel mixture right, whether you're restoring a barn find, improving performance, or just keeping your vintage bike running smoothly. Easy to install if you're comfortable with carb work: just remove the old jets and screw these in. Great for DIY mechanics, CX500 enthusiasts, or anyone who loves tinkering with old Hondas. Always double-check jet sizes against your bike's specs. A small part that makes a big difference in how your motorcycle runs. Keep that classic twin purring!
