    Hello everyone, I was hoping somebody might be able to chime in on where to start on this issue. I recently rebuilt the carburetors on my 1984 cm450e, when taking it for a test drive i found the acceleration would quickly get sluggish as my rpm's go up. I thought this may be a firing problem so...

    Hi! My name is Ian, I live in Seattle. I've been riding since I was 16, and I had a Suzuki GS500 for about 10 years. I sold it when I moved to China for 2 years, and since I've been back in the US (about 5 years), I have been bike-less đŸ˜­. Well now I've finally filled the motorcycle-shaped...

    Hi all. I'm a husband and father and have waited until Corona World to get my first bike. Not because I haven't wanted one, but because the wife finally gave me the green light (...in case of the apocalypse)! I bought a 1982 Honda cm450c with only 5400 miles. It needs a few things and a tune-up...

    Hello, I have been a long time lurker of project bikes and last year I bought one! It’s a Honda cm450c here is my progress so far!

    Hey guys, so a few months back I purchased a 1982 Honda CM450C..Seller said it had 8000 miles on it, and he put 200 hundred on in the last two years. The bike ran like **** and looked like it as well. In fact I crashed it during the test ride, as I was going to pump air up in the tires...
  11. Fuel Supply and Carburation
    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...

    In this thread I hope to save the life of a truly dear friend. My trusty steed... my faithful companion. "Thumper," the 1981/'84 CM400/450 hybrid that I learned to ride my first miles on. That went down with me in a tangled mess time and time again as I pushed the envelope of what we - together...

    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...
