I am reposting this cuase I'm not sure if everyone reads the Wanted section . . .

Does anyone know if a 1978 CB750 Rear Caliper will fit on a 1976 CB750F? The caliper looks different and I think the issue will be fitting the length of the hose. The brake hose goes to the front of the caliper on the 76 and it looks like the rear of the caliper on the 78?

Also, I found a guy in Florida with a CB750F tank that looks to be in good condition along with a working caliper. He wants $125 including shipping to PA for the both of them. Am I crazy for even considering this?

the answer is.....no

77-78 cb750F bikes use comstar rims and completely different brakes.

the 77-78 tanks are almost the same as the earlier tanks except for the petcock, so if you get the tank get the petcock. I paid $90 for a really nice F tank (for a dual cam) over the weekend so offer him that for the tanks and see where it goes from there.

that tank is definatly not from a 75, it is a 77-78 tank. Since they are interchangible it is not uncommon for a later tank to end up on an earlier bike but that tank did not leave the factory in '75. It will work on your bike but you need the proper petcock.

Just out of curiosity (I'm not doubting), how do you know it's not a '75?

Paint is the 77-78 black paint scheme right of the bat. Sure it could have been repainted with the decals but based on the "patina" I am guessing it is the original paint scheme. Even if it was repainted I doubt someone would go through the effort of putting the decal on the gas door too. If it were a 75 tank, with original paint it would be either candy saphire blue or Flake sunrise orange.

Also the emblems have the word supersport molded into them. the 75-76 emblems just say honda and the words super sport are decals below them.

also the shape of the tank tunnel inside the tank looks more square, 75-76 insides are more rounded. It is a bad pic though

the only 100% sure way to know is to figure out the thread of the petcock bung on the underside.

That doesn't mean someone didn't put that later tank on an earlier 75, they are interchangible.

So I found this tank on ebay: http://cgi.ebay.com/ebaymotors/ws/e...STRK:MEWA:IT&viewitem=&item=280137783850&rd=1

It says it's from a CB750K model but it looks like the F model to me. What do you think? I'm trying to get my hands on a stock 75-76 F tank. As I've mentioned, my tank is all messed up. I tried mounting it today and it is definitely too long for my stock mounts. It is zip-tied on there until I can find a cheap stock replacement.

Bump! Anybody? This auction is almost ending.

that tank is the stock 1976 cb750F tank in the stock Candy Anteries Red. Looks good to me, espically if it comes with petcock and is clean inside.

What tank do you have on there now? cb750 tanks are all interchangible (except for seat issues) so if you have to zip tie it on it is not a cb750 tank.

BTW, make sure you are pushing the mounting cups all the way on to the rubbers, otherwise the tank will appear too long.

I have no idea what tank this is:



I'm pretty sure it's pushed all the way forward but I'll double check.

It doesn't matter though because I lost the tank at the last second by $1. That's the second time that's happened to me and it's really pissing me off.

underneath the tank toward the back (you can see it in the pics) is a tab that is supposed to slip into a rubber mount. it looks like the rear rubber is not there otherwise the tab would be sitting on it.

How much do you have to spend on a tank and such? I can look around to see if I have a good 75-76 tank. I know I have one I need to blast and put a liner in, it is for a friend and he is moving so he told me I could keep it, I was going to prep it and put it on ebay, but if you really need it we can work something out. I need to check if it is a true 76 tank though.

that 77-78 tank for $1 was a bargain, even if you paid $50 for a pingle petcock you would still be ahead.

That's the guy that told me $125 for both the tank and the caliper but the caliper was wrong. Last I heard from him was that he found one for my bike and was going to send me a picture but never followed through with it. That's what I really need, a rear caliper. A new tank wasn't really in the budget unless I can get a good deal on it and I'd hate to short-change anyone on here.

The bleeder screw is broken off and frozen inside the caliper. And I've added a broken extractor in there to boot. <img src=icon_smile_sad.gif border=0 align=middle>

Speaking of the devil . . . I sent the guy with the tank another email and he responded with a picture:


He found the 1976 rear caliper that he had and said it's pretty beat up. Supposedly the guy he got it from beat the hell out of it. But he'll include the brake hose with it.

And this is the tank: http://cgi.ebay.com/ebaymotors/ws/e...STRK:MEWA:IT&viewitem=&item=330149214917&rd=1

What do you think? Worth $95?

hard to say. Offer him $70 and see what he says, you can always negotiate up. Right off the bat you are going to need to clean up the pad slider rods (don't know their real name) since they have rust on them. Plus that sucker looks like she needs a rebuild - badly, and you have no idea about the piston (if corroded you will need a new one and last time I checked the stainless steel ones are about $35+).

figure the tank is worth anywhere from $50-100 depending on how bad someone needed it, and that caliper is worth $20 (if that). I have a hard time believing that that nasty caliper is better than the one you already have on your bike.
