GENUINE OEM HONDA ENGINE CARBURETOR INTAKE REED CAGE or REED Block. Should fit 2003 to 2007 Honda CR 250's and this stock OEM CR 250 Reed Block was off of my 2003 CR 250 and I believe have new Boyesen reed replacements in them. You can tell they were taken off when new and never used. I do not have the Rubber Intake Boot flange, but have seen them here and on Ebay if needed. I have a stock CR 500 Reed Block as well if you need that. Thanks for looking and Happy Holidays!!!
