Does anyone know what for what years a CB750 tank will fit a '78 CB550? There are loads on ebay and I've seen a couple of nice bikes that claim to use one. What measurements do I need to see if one would fit?
I saw a CB550 with a CB750 tank that I liked the look of and was just wondering what years would fit. Actually, it seems as though quite a few 750 parts will fit. I discovered that I need to rebuild the front master cylinder and in looking around found that the 550 shares the front brake assembly with several CB models. But you're right, a CB750 tank is definitely not manx inspired.
Glass or aluminum tanks are between 500 and 750 dollars so thats your ,price gauge any thing below that is a good deal if its big and steel and has looks you like.If its in steel its fabrication and welding to get it to fit ,If its glass its fiberglass resin and gel coat madness.
There are a few hondas on that page which tank exactly were you referring too.
the dunstall tank on the 400/4 is not the same as the dunstall or dresda tanks that fit the cb750 and 550 (I think that the tank pictured is actually an old dresda not a dunstall but it could be). A stock sohc tank can look good if massaged properly. I really like this tank and it is just a stock 69-76 tank with the emblem goles filled in and an old 60's honda motorcycle badge on the tank:
for reference the 1969-1974 tanks have a right side petcock, 1975 and 1976 have a left side petcock. see which will work better with your setup.
dresda still makes a universal manx style seat, same one they made back then and it looks like the one on that 400 four (because it has the cutout for the dresda over the tank mount).
anyway, omar's DTR has a cool manx fly screen that looks like it will work with a lot of bikes. see their yamaha xs650 conversion kit.
I've looked at Omar's flyscreen - very cool. I'll probably get one eventually: right now I'm concentrating on getting it going (slow dealer. 'nuff said). I'll check out the Dresda seat, it sounds about right.
The green #73 Honda is a cool looking bike, especially the tank emblem.
