Rebuilding a 1970 CB750

[clawdaddy13]

Hello everyone new member here. I have recently inherited a 1970 cb750 with less than 10,000 miles on it. It has sat in my grandfather's garage for over 10 years. The engine is not frozen up and seems to have good compression. I am not real mechanical so I was going to have most of the major stuff done at a shop. Then try and do minor things here and there myself. Any ball park estimates on what I can expect to spend? Looking for any advice, websites , etc....Thanks in advance. I have attached a couple quick pics of the bike.

With shops you have 3 options: good, fast, cheap. you can pick one of the 2. First off, if you have a shop do it, it will cost $$$. Not only in parts but they will rape you sideways with barbwire.
Judging by the photos, you will need a LOT of time to clean things up and a lot of parts. Your best bet is to get a manual, preferably a honda manual, for the bike. Get some brillo, steel wool, or scotchbrite pads and some chrome cleaner. Clean your forks and exhaust. See if you can save those. You WILL want to take them all off completely. If you can save those, that will save you some serious dough.
At this time, I will estimate $1000 in parts but that could change after a good washing.
Ultimately you will need to go through the whole bike probably. You might not have to pull the engine apart but be ready for some time spent.

Great that is the kind of information I am looking for. Anything to make the process a little easier. I have a shop around here that gave me a quick estimate of around 1000-1500. I just dont want to get in over my head spend the initial money to get it going and then have things going wrong here and there that I can't ride it.

Nice find! And under 10K miles. Re-run is right, watch out for shops unless you know them they can and will screw you. I had one fu*k up a new paint job and try to deny it. You will need to replace all rubber, tires, cables, chain. The seat looks good. Take a good look at the inside of the tank. I'll bet it is rusted, and will need to be acid etched and recoated. The carbs will need to be cleaned and rebuilt. Gas left in a bike turns to varnish and will gunk up everything. Check the oil, if it is really dirty you should tear down the motor or at least flush out that old oil. Don't forget to drain the oil tank also. You can pick up a Clymer or Haynes manual for that bike alot cheaper than a Honda factory book. Mine even has a color wiring diagram. About $30. That should be the first thing you buy.

If you know where to look, you can get the honda manual for free. I did and it was for a K8.

Yup, you just need a printer and alot of time. Preferably a color one. The internet is a great resource for old manuals, but the Honda ones are only $30.00. The Glenns for Kawasaki triples are $300!

Part it out and buy a bike already restored, you will save your sanity!

[Re-run]

But you will spend a lot more and not learn the bike. then if you have problems, you will still not know how to fix them.

He is planning on having the work done at some shop. He could probably buy an Sandcast from Vic World for what he will have if someone else does all the work!!!!!

[Re-run]

Maybe but the point it to encourage him to do it himself. Regardless of whether or not her gets it on the road, it will be a great learning experience. If he does get it on the road, we will also have the tremendous pride of being able to say he did it himself.

Well I plan to do what I can, I just wanted to have the major stuff done at a shop to make sure I dont ruin anything and to get it up and running. Then I could try and do little things here and there as I have time and get more familiar with the bike.

got a pic after a little bath..

Sure looks a lot better after a wash. If you could do a close up, that would be great. Have you taken off the fork covers yet to see their shape or started any other work?
