restoration

I have a CB750E, it has been in storage for 30+ years (Not locked up) Need advice on what to do first?? Change oil, clean carbs ? or just put fuel in and try to crank?

Trying to determine the value of this exhaust system taken from a 1978 CB750K with 3K miles on it, pipes are in excellent condition... numbers on the pipes are HMCB750K HM405 SANKEI 2025, have done some research but can't get an accurate idea of what they are worth.... thanks for the help...

I've been searching on-line and hard to find answer, sorry if this has been covered. Looking to replace the gas tank on my new 82 CB750SC. Hard to find anything without dents and/or tons of rust. Was hoping to open up my search. What other tanks will fit WITHOUT welding? Thanks all!

Will serve as base for my first project. I'm going to pick her up after New Years Eve. Lots to be done on this, and hopefully get her in shape by summer. Will certainly be back with a zillion questions along the way... :D BTW, I made a very simple ramp from a ladder and some board cut to the...

I've searched but couldn't find exactly what I was looking for. I have two tanks for my 73 CB750. Both have rust in them. I eventually want to hand shape the knee pockets. Should I de-rust the tanks first or shape them first? I know that by shaping them I'll knock some rust free and...

Hi, I wonder if anyone on the forum can help on this one. The main cam chain tensioner for the crank to cam chain on my 1980 DOHC CB750 F has broken, reading the work shop manual it seems to say you can remove the tensioner without taking the head annd barrels off, can anyone help, how much of...

I've got a leak in the front left corner of my gas tank. I need to take it to a shop to have it patched but first I need to completely drain the tank. I've already drained most of the gas from the tank from the petcock. There still remains a small amount of gas/water in the tank. When I roll it...

I everybody this is my first post and comment on this site. Hi for Bend Oregon land of lots of sunshine. I just bought ,last night,a beauty 1975 CB 750 for what I call cheap($790.00). It's in great shape and all there but the engine has seized FROM SITTING. Has anyone had any experience in...

There were at least a couple of setbacks that had me wanting to chuck this old bike. Now that it's finally done people walk up and ask questions more than 1/2 the time that I stop somewhere. Yesterday I stopped at a convenience store and when I came out 3 guys were standing around the bike...

hi all I bought my old mans 1982 cb750 off him last year as a project bike with the plans of doing a complete rebuild on it. I have ran into some problems when it comes to the engine. I have removed the rocker cyclinder head cam chain tensioner and the one bolt that holds the bore to the...

Hey all! Glad to be here! Ive had this bike longer than any vehicle I've ever owned... I got it when I was 16 (29 now) and spent almost all summer (back then) trying to get it to run. It was miserable and frustrating and I had no money to rebuild the carbs, and the guy I bought it from...

Hello Everyone! I am new here but I have been following along for a little while now. I have been debating whether to completely restore my 1976 cb750 or to just customize it into a cafe looking bike. Not sure I am going to keep this one so it would be more for resale. So i guess my question is...

Anyone have experience rebuilding left control unit? My original quit providing power to the running lights. Bought a used and new unit and neither of them work to the wiring diagram. Diagram I am using shows power coming into the switch on a brown with a red tracer. It provides power to...

Dear users of cb750.com, I am a 16 year old boy who loves his bikes. A couple of years ago my dad bought me this beautiful 1997 Honda CB750F2 for £50 and was rusting away. I told myself that i will restore this bike however I never really had enough time until now. I have been looking online now...

Greetings all! I purchased my dream bike this past November ('78 CB750K) in decent shape. With the help of my friend (,neighbor & go to mechanic), it is running and looking pretty good minus a few cosmetic things. One of them being the reason for this email. What have any of you found and...

Hi guys, New member here & newbie to old bike restorations. I have a 78 CB750 & I'm trying to take it back to a similar look. The guy I bought it from switched the seat out to a king & queen. I want one like it's supposed to have. Do restoration guys just search until they find an old one &...

Ex Aircraft mechanic with bum back problems, just picked up 80 CB750F for my son 22k miles, plenty of spares including extra engine. Turns over smooth, oil clean cams look new great spark but no compression, should i check timing before valves any advice would be great. Thanks Ken

Hoping someone can help. To save money I cleaned and reassembled my rear master cylinder rather than rebuild it. But I do have a very, very slow leak. As owners of the F1 know the rebuild kit for the rear master cylinder is almost unobtanium and expensive when found. Almost $90 on ebay. Does...

Hello, I'm new to this forum and am looking to get my CB750C in working order. The bike was given to my dad in 1997 in perfect physical and running condition. I'm sad to say that after a few months he never rode it again and said it would be mine when I was old enough to ride. It was never...

I have a couple of extra side covers that I am going to restore. I have checked all my links and can't find a color code or best match for the grey they are painted. Any help would be greatly appreciated. Thanks Jeff

Ok so here's the problem: I bought a wreck of a cb750 (1981) as a project café bike. cylinder block has 900cc on the casting near the base where the gasket to the crank case is. The guy I bought it off said that the 750cc crank case was interchangeable with the original 750cc cylinder block...

Japenese parts supply for the 750K's, see it here.

Not sure if this is the correct spot to post this. I currently own an 82 CB750K, that needs some work, but I was contemplating on getting an 84 CB700 nighthawk S too. For the guys that know most about these, is the 750 ultimately the better choice to restore? Keep in mind, the 700 is in better...

Hello all, I have started a build project of cb750k 1981 DOHC. I'm trying to build a Cafe Racer for me. So I enjoy much in doing so. Mostly ... I have a bit of a problem and I hope that some of you good people can help me. I have started with rebuilding the carbs first. And as you can see in...
