Intake Boot Clamp Arrangement Diagram ?

[EMS]

Mike:
I think you are correct except for one thing - from '80-on Honda put the #2 carb side clamp in the 9 o'clock position for access and non-interference with the vacuum fuel valve line.

Dave

Dave: Are you saying 9 o'clock: The screw head points "up" or "down"

[daves79x]

Uh - up, unless you have a real stubby screwdriver and are a contortionist. That's the way every '80-'82 that I've worked on (that hadn't been messed with previously) had the #2 clamp and Pete Ruff's chart in the Xpress confirms that.

Dave, I don't know. Just out of curiosity, I stopped by Frank Coe's who has a 1980 still in the crate and tried to look at this. For one thing, the vacuum valve sits on the airbox side of the carbs. From what I could see, there is the vacuum hose runnning from there over the carbs to the front between the carbs and the head, but it clears both clamps of the carb-to- head manifold of cylinder No 2 and both clamps have the screws oriented at 12 o'clock. Now the airbox to carb clamp at the No 3 cylinder, I can't see a screw head and this is what you may think of. I didn't have a camera with me and it is difficult to get to, but I asked Frank to try to take a picture and send it to me.

Thanks Dave, for confiming that while I may be nuts, I wasn't imagining that there is a difference in some years.

Mike:
I had 2 different nearly out-of-the-crate '82s and they had the #2 carb side clamp in the 9 o'clock position. And I've seen many others like that. Also, one of the inboard two (#3 or 4) airbox clamps goes down - not sure which.

Really ? So you have to take the tank off to get to one screw ?
The way I found mine you can get to every screw head without removing anything.
I'm still looking for that diagram I keep remembering.....

[daves79x]

To remove the carbs or tilt the engine, yes, I usually remove the tank. I'm just telling you, that's the way they came from the factory - put them any way you want.

I wholeheartedly agree, Dave. That was my point all along. The whole thing is a non-issue anyway. If you go through the carb installation step by step, I see absolutely no problem arising. Anyone, even with no experience, will find out what to do: First, you install the manifolds and clamps to the cylinder head. Here you will already have a first indication what will work and what will not. Even if you overlook something, when you push carbs into the manifolds and tie everything up, and you can not, you pull the carbs out and relocate the clamps. Piece of cake. All that is done BEFORE you tilt the engine up. Nobody will try to tighten the clamps AFTER you tilt the engine back up, will you?
Here are two pics from my archive. First one shows all manifolds and clamps on the head. Everything oriented the way it works on a 79. Second one is a shot of a late model, especially No 2 location, with the vac line. Clamp points to 12 'o clock on this one. Supposedly the carbs have never been off. But who can vouch for this on a 30+ year old bike?? But this is how I saw it on the crated 80 yesterday.

...But this is how I saw it on the crated 80 yesterday...

Hrrrrm? "Crated 80 yesterday"?

What are you referring to here Mike?

You are not reading the forum very often, Nils, do you? There have been a couple of threads where I talked about my friend Frank Coe who has a 1980 CBX still in the crate.

Dave, I don't know. Just out of curiosity, I stopped by Frank Coe's who has a 1980 still in the crate and tried to look at this.

The bike is not for sale. Frank bought it for $12,500.- 5 or 6 years ago. He was going to put up a museum locally together with a few investors and enthusiasts, one of which is a dealer of exclusive cars. The recession in 2008 put a stop to the program. I am not sure, if they ever get going again, but the bikes they have are in their individual collections. Frank has 5 CBXes, including the crated one, a NR and an immaculate CB1100RD, among other things - which include a 1974 MV Agusta 750 Sport

It's funny what the omission of a single punctuation mark can do.

"...But this is how I saw it on the crated 80 yesterday."

"...But this is how I saw it on the crated 80, yesterday."

Life is in the details.

Also, one might tighten all the clamps before the motor is tilted back into position only to find the intake assembly needs some flexibility in order to get the air-boxes aligned and together. For this reason it's wise to leave the intake clamps a little loose so things can be 'massaged' into their proper positions.......then when all is located and positioned....... tighten all clamps securely.

Ok....sorry....... I was looking at the screw access too narrowly. The tank needs to come off to remove carbs or tilt the engine. Common sense.

I was thinking if one wanted to check if all the clamp screws were tight..... the way Mike Simon's photo shows..... all of the screws can be accessed without taking the tank off...... that's where my head was.

Also....the pic Mike has given us is excellent.......but the motor is black. Were there black motors in 1980 ??

Thanks.

Bingo!

These pics are from my 82, that as far as I know has never been "molested". The #2 carb side clamp is rotated and flipped, so you can access it from the top (first pic).

The #3 carb airbox clamp is on the bottom. On top there is no space for it due to the fuel shut off valve (second pic).

On a hi-jack note, pay attention to the freshly ceramic coated valve cover, the newly polished cam caps, and the nicely powder coated engine mount (long winter ).

Spring is Coming!!!!!!! Steve

[Mike Cecchini]

Looks good Steve.....and the 9 0'clock position of #3 is clearly shown. Thanks.

Watertown eh ?? I use to come through there all the time on my way to the great white north for track days at Mosport. Last stop to get familar food stock-up, beer and gas at reasonable prices. Canucks sure pay some steep taxes on on gas and brewski.

My best.
