Welcome back to our channel, gearheads and adventure lovers!
In today's episode, we are embarking on a mechanical journey to restore the heart of a classic, the fuel system of a 1978 Honda CB400A Hondamatic. This iconic machine may be over four decades old, but we're proving that it still has a lot of life left in it!
We start off in the garage, where we take you step-by-step through the entire process of overhauling the fuel system of this vintage beauty. We'll cover everything from the basics such as fuel tank and carburetor removal, to more advanced topics like cleaning, inspecting, and repairing components. For those of you who like to get your hands dirty, this is a perfect DIY guide to bring your old Honda back to life.
Once we've given the CB400A the TLC it deserves, we hit the road for a scenic ride through the beautiful Big Branch National Wildlife Refuge. Get ready for some breathtaking views and the pure, unfiltered sound of a revitalized '78 Hondamatic roaring through the wilderness. We'll show you how this timeless motorcycle takes on the open road, and why it's still a charmer after all these years.

FSM recommends removal of the fuel tank. I spent the effort to remove the air box and carbs to replace the old "manifolds". I also replaced the JIS screws with 8mm head bolts. Now I can just remove one of the intake boots to make space.

[@motorcyclerewind]

That probably would have made it easier.

[@DogMania]

Love your Hondamatic Content, along with all the other bikes! Keep up the great work!

[@motorcyclerewind]

Thanks so much really appreciate you watching.

I have quad carbs on my 2003 Suzuki Bandit 600. Getting them back on is such a chore. I find a little silicone grease on the inlet rubbers helps them slide on much easier. That little 400 is such a great looking bike.

[@motorcyclerewind]

The silicone grease is a great idea. The heat fun helped alit. Thanks for watching.

[@willeel3750]

Your helper gave me a chuckle. I have one too . He is a little younger than your helper. I'm looking at a 400 right now with a manual transmission. Loved the "herding cats" comment. I use it often. Hang in there and great work. I subscribed.

[@motorcyclerewind]

Thanks for the subscribe. My helper is Jackson, our grandson. We are fortunate to get lots of time with him and his little sister. Thanks for watching.

[@truckstotractorsrepair]

I just picked one of these up, same color. Im gonna swap a 5 speed engine into it though. Dont really like not shifting that much😂

[@motorcyclerewind]

I can see it being a love/hate relationship. The swap sounds fun! Thanks for watching

[@peterturnbull9133]

Good Video - the bike still looks great in my view - I had a couple of CB250N Superdreams with a very similar engine as my first bikes. I still have an affection for this engine. Also got to ride CB250T model (think it was the Hawk in the US), Very similar to the Hondamatic in terms of style - it was a lot of fun and I my lasting memory is thinking the seat was really comfortable. The CB250T / CB400T models were only available for about 1 year before being replaced with the Superdreams in Europe. PS - I still really love the Comstar wheels on the 70's / 80's Honda bikes.

[@motorcyclerewind]

This bike is so comfortable to ride. Thanks for watching.

[@user-jp7vj2ky4r]

What battery would u recommend..I just got bike..no battery though

[@kennethwinter5665]

I have the same engine.. It runs GREAT after carb clean... BUT it will not return to idle. What would cause this?

[@motorcyclerewind]

By not returning to idle you mean staying at higher than idle RPM.

[@ThatOldHonda]

Once you have the carbs loose - remove the boots connected to the head - gives you loads more room, careful of the o'rings behind them

[@motorcyclerewind]

That would be way easier than wrestling with the air box rubbers.

[@ThatOldHonda]

@@motorcyclerewind me removing carbs from my CM250T - basically the same bike kzbin.info/www/bejne/jWGwoHdmmZ1ojZY

[@yomommaahotoo264]

A whole different kind of riding with that auto for sure. How does anyone get a cleaned gas tank dry fast?

[@motorcyclerewind]

To dry a tank after cleaning. I use my shop vac to blow air into it for about 30 minutes.

[@baylorharding4499]

Curious on if you set the idle speed or synchronized the carbs after putting them on? I have a 78 Honda cb400a I'm working on right now and have loads of questions lol

[@motorcyclerewind]

Send me an email with your contact info and we can talk about it.

[@baylorharding4499]

@@motorcyclerewind sent you an email havent heard anything yet

[@64fairlane305]

Sounds like a one-speed automat

[@motorcyclerewind]

Loads of fun. So smooth. Thanks for watching.

[@ThatOldHonda]

by the way, you can change the floats without taking the carbs off the bike :)

[@motorcyclerewind]

Now you tell me😂 Hope all is well with your V65

[@ThatOldHonda]

@@motorcyclerewind V65 needs a timing chain (I think) it rattles like a can of marbles - hear it for yourself, quieter after setting the tappets but still rattling kzbin.info/www/bejne/rpWwlnafp7mKpqc

[@chrisstokley7687]

now days : always convert it to single bigger jet carb= less plug ups-easier maint

[@motorcyclerewind]

Thanks for the tip.

[@chrisstokley7687]

2024=$tree slie plumbers jell = acid= cleans rust really welll.. 24 hr wait..

[@motorcyclerewind]

Thanks for the tip! Will have to look for some. Thanks for watching

[@grabread]

It looks like the exhaust shields are on the wrong sides

[@motorcyclerewind]

The little shields that cover where the muffler connects to the header? I will look into it.Thanks
