Rated 4.5 out of 5 stars.
If you're rebuilding the top end on your '83 or '84 Honda XL600R, this Caltric valve set is what you need. You get two intake and two exhaust valves, all brand new. They're direct replacements for the OEM parts 14721-MG3-000 and 14711-MG3-000. They've got a nice chrome finish and are made from solid metal. Each valve measures about 104.2mm long. They come sealed and ready to install. Just a heads up, there's a Prop 65 warning for California folks. Get your dirt bike back on the trail with these.
