    Anyone find a set of compatible aftermarket air intake boots (rubber tube between carburetor and airbox) that fits either a CM400A and/or CM450A with stock carbs and airbox? Honda sold 'em with the airbox on these bikes, which means no separate part number for me to search. Apologies if this...

    Anyone find aftermarket mufflers for their CM450 that look like OEM/stock, and aren't much louder? I know this is the opposite of what most people are doing to their CM450s... switching up muffler styles and going with something louder. I laid the bike down in an accident and scraped up/bent...

    I purchased my 1982 450 Nighthawk fifteen years ago from the original owner. It came with two sets of luggage rack support brackets. One set fit my Nighthawk perfectly and the other set did not. The bracket would hit the side cover but the bolt holes lined up. I was cleaning up my shop and...
