Hello everybody. I have been lurking around these forums for the last couple months, contemplating the purchase of a cycle. An '82 popped up on craigslist, and i am taking a shot on it.
I have owned a few cycles in the past, including a 1999 honda shadow. Its been about 6 years, a wife and 2 kids since i have been on a motorcycle. Looking forward to hopping back in the sadle.
Enough blather. I'm sure you want to see a few pics of the bike.
This was how I bought her. The PO was a mechanic, both as a (previous to retierment) proffesion and as a hobby. We got into some good conversation, but unfortunatly the bike would not start (my wife would kill me for buying a bike that didnt run). He offered to get her going again, if i would agree to purchase her when he did. We agreed, and the next day, i helped him pull the carbs. He was going to set himself up for tearing them apart, and i asked if i could do it. I left with them, and over the course of the next week, i cleaned them up.
I brought them back, reinstaled them and now she runs. I am the proud new owner of a 1982 cb750!

Here is a little look around her. Everyone likes bike pron.
Little rusty in the frame and chrome exhaust
First little issue. The gromet inside the eye of the rear right shock is crushed out the side a bit from where the hondaline rear bracket attached. Not sure if i have to replace the gromet or if i can get away with snugging another bolt on there, with a thick washer on either side. These will get replaced in the summer, but if i can get away with them for a few months, i will.
My carbs before i cleaned them. Is that the "Son of Satan" in the bottom right corner?

I would like to add one thing as well, thanks to all who post here. Shinyribs, Sgtslag, Slonugly, Seestheday, TOOLS, Piute, and anyone i may have missed. I have read for many hours, looking at builds, reading advice, and just generaly getting a feel for this place. Its seems like a wealth of knowledge laced with humour and general well being.
Cheers!
This is how she looks at the moment. Just a few things to do to get her legal again!

Hey, thanks for the call out What you pictured there is the spawn of Satan. Easy to take off, just make sure you add a fuel filter if one isn't there already.
Quick question for you, while tearing down the carbs did you split the bank, and if so, did you see any felt washers?
Regarding the shocks, you might want to use this opportunity to put better shocks on. It is fairly well accepted that the stock shocks are pretty bad, especially after 31 years, and anything new will be a big upgrade in ride quality.

If you do decide to remove the SoS, you will need to use the fuel petcock religiously. The SoS was there to prevent fuel from flowing if the engine were turned off, in case of a crash or some other malady. If you ride the bike every day, you shouldn't have a problem leaving the SoS on there. I had one on my '79, and it was only a problem if I didn't ride it for a few days: I'm guessing the gas in the carb bowls would dissipate, and I'd have to crank the engine a bunch to deliver enough vacuum to open the valve to get fuel to the carbs.
The bike looks very nice, and I'd say you got a good deal. I like a nice friendly transaction like that.
+1 on the new rear shocks. ANYthing would be better than 30 year old stock dampers. Might as well do the fronts while you're at it. Simple procedure, and well documented on our forum.

Looks like it came with the Hondaline luggage, and fairing. Those are pretty rare -- especially on 750's! If you don't care for it, be sure to offer it up to those who might (not me, but you could get a decent price for them, if shipping can be overcome).
Nice looking bike. Appears to need some minor TLC, but not bad. Be sure to check the age on those tires... Even if they look good, they should still be replaced if more than 3-4 years old.
You mentioned replacing the shocks, in the Spring. I would highly recommend Progressive Shocks, and Fork Springs: it will ride, and handle, like a modern bike. The improvement is quite amazing -- I did that on my '79, and I couldn't believe it was the same bike. Welcome to the forum, and the world of CB750's! Cheers!

If you're as fastidious as I am about keeping the carbs clean then turning off the fuel petcock is really personal preference IMO.
If I have a small fuel leak after leaving the fuel petcock on while it's not running then I know I need to pull and clean the carbs.
I haven't yet walked in a large puddle. I'll see how this goes, but for now I'm assuming I'll see a small small leak rather than a large one. I do have faith that large chunks aren't going to come out of my gas tank liner and get through my fuel filter though as I've been running the bike for 2 years now.
For what it's worth I ran a full year turning off that fuel petcock when I stopped before I got this confident (I've also rebuilt the carbs twice in that time, the first was just to generally clean then, and the second time I was really thorough).

Thanks for the compliment myTunes. That bypass information is great. If I start having troubles with it,I know what to do!
Seestheday-I did not break the carbs apart. No ideas if there is felt washers in there. As for the shocks,I knew I would have to replace them,I was hoping I could make it till late spring to do them. I may have to spring the $400.00 and replace them now however...
Luke-missed you in the shout out. Thanks for the advice on the SOS. Yeah, the purchase was great, made a friend (and someone who has a lot of tools and advice), and picked up the bike for $900.00. Win/win.
Sgtslag- it is original hondaline luggage/rack and fairing. It would be a hard thing to let go, but I might find I am not using it, and will offer it up to other forum members should this be the case.
Lucky-good catch on the name. I just wanted to give my thread a little difference in the title. Yeah, that seat is gonna get recovered in the summer (or earlier). There is lots of reasonable priced covers on Ebay.
Piute-thanks! If I do any touring the bagger will be back in action. As for now, most of my action will be around town, to work and such. The engine is so much easier to get at without the fairing in the way!

There is supposed to be a snap-on backrest pad for the passenger. It attaches to the bottom/back of the trunk bag. Do you have that? Just curious. If not, try trolling e-Bay with an automatic search, or perhaps an upholstery shop could fabricate one for you. That is the only thing I see missing.
A friend had a 1981 Wing, with Hondaline luggage. It was quite nice: hard, quick detach, luggage; the trunk is nearly identical to the side bags; lockable. It was a nice set, but it does not appear to have sold well, as I have only seen a few of them, even with e-Bay. Modern touring luggage has mostly converted to soft, removable, liners inside of hard bags/trunks, rather than detachable/lug-able hard bags. I had soft bags, that we unhooked, using carbiners, from our Honda. They worked, but they were a lot of hassle, compared to the removable liners we have now, on our Voyager. Still, I kind of envied my friend with his hard bags, as they unhooked quick, and they looked easy to carry.
I'm a died-in-the-wool tourer. We exist six months out of the year, waiting for the riding season, so we can hit the road. It is like a drug to us, but the side effects are also the benefits! Here's to wishing you get bitten by the touring bug -- you have the bike gear, now you just need some vacation time, a map, and some beautiful scenery to drink in. The freedom is intoxicating... Cheers!

Thanks for the info Sgt, t don't own that piece, must have gotten lost by one of the previous owners. I will keep my eyes open!
This weekend i got down to changing the oil, air and oil filters, and started the wiring for the headlight and turn signals. I was warming it up and noticed it was only running on 3 of the 4 cylinders. It idles pretty smoothly (even on 3) but the idle sits pretty high (at 2.5 or so). I'm thinkin' i will be able to turn it down once i am firing on all 4.
This friday i will be testing for spark on the #2, and then probably pulling the carbs again to have another going over. I seem to remember the vacume slide sticking on that carb, maybe i will polish the slide and see if it cures the problem. Any advice on what lubrication i should use on the inside of the slide?
Next up will be going to go to a fastener store and see if i can find some mounts for my turn signals and some stainless allen key hardware. If i have any time left, i will retension the cam chain and push grease in all the fittings.
I will take some pics and upload them on the weekend!

Quick update. Pulled the carbs today and checked all the jets. Seems I missed the idle jet in my #2 carb. Cleaned that, then assembled the bike again (all in under1.5 hours). She stared on the first turn, all four running smooth.
I wish that was the end. I had removed the drain hoses from the carbs to make them easier to replace. I did not replace them before I started her up. She started puking gas out her #2 and #4 carb drain, even when I tightened up the drain valve.
So my question is this. Could this be caused by the SOS? Lack of hoses on the drain nipples? Or is it obviously my float needle? The reason I ask is because they worked just fine before I removed the carbs today, and now 2 of them are overflowing.
As a side note,I will be fabricating my turn signal mounts out of some aluminum bar stock I bought. Being as this is my first time doing it,I will take a few pics along the way and share with you all.

It could be a stuck float valve or a cracked needle; if the gas is coming out of the nipple. Usually it doesn’t overflow out of the drain. Check for cracks in your bowls. You can try tapping the bowls with a screw driver to release the floats or you might have to take the carburetors back off and polish the inside of the float valve seats, also you might want to check to see if your floats are holding gas. Shake them to see if they are. If you do take them off go ahead and do a good cleaning on them. Just follow the directions on this link. I like to ride it to see if it clears up first. Mine would leak a little after I did my carburetor cleaning, but it stopped after a long ride. Don’t go far from the house if it’s not running right though, and you might want to take it easy until you condition the seals. Just putt around the neighborhood and get some air to her.

I had a leaky carb one time that was giving me fits. I fiddled with needles,seats,float level....til I was about to pull my hair it. Turns out the overflow tube itself was cracked and leaking. I smeared JB Weld on it.Fixed!

OK, went in today, and even with the petcock turned off,I found a little gas puddle under it. The petcock is an aftermarket job, I will be replacing it for sure. Its always a trick fitting these petcocks (from what I have read ),I will have to do some measurements to make sure I get the right one. I wonder if this has anything to do with my "leaky carbs". Time will tell,I will be ordering float needles for them at the same time, and see if I can fix it all at once.
Anyways, I decided to move on another project while I look for parts. I pulled the front of the bike apart, so I could replace the atf fluid in there, and install my gaiters ( I like the looks of them) and my new headlight ears. This was a little intimidating as she has air assist forks, and I have never done work on them before. All went smoothly however, and I learned a few tricks along the way (make sure the Speedo cable housing is facing the right way before installing the wheel for example). Forks, wheel, and brake are back on her, and the gauges and cable reroute will happen next weekend (unless I can get out of the house tomorrow).
Again,I didn't get any glamour shots of my bike, but some will be incoming soon.

Well I went out to the garage last night after the kids had gone to bed. Not much I could do in the dark, but I certainly gave it my best shot. Cleaned the speedo, tach, and throttle cable. Rerouted some cables I mislaid in my haste to replace the forks. Brought the bars and controls into better position. Cracked another beer. Installed my bar end mirrors. Played with my ignition (might need to get another one). Found out that my $3.00 turn signals need to have 3 wires for the front (i bought some that only had 2, they work in the back). Hit the crome up with some 0000 steel wool. 1000 grit sandpaper to remove some of the corrosion on the outer engine case.
So now the list is shortening on things I have to do. New petcock, look through my carbs (again, might take off the SoS and replace with fuel filter), lighting (find some 3 wire units), Make some brakets for my turn signals, and a few misc bolts and washer replacements and she should be steet legal. Looking forward to putting some K on the bike, And being able to get to some cosmetic upgrades (polishing!!!!).

Tried to start her up today. It was cold, so gave a few turns on the starter. Carbs started leaking gas out the overflow tubes again. Out came the battery box. Our came the airbox. Out came the carbs.
Covered up the intake Ports. Scrubbed the engine a bit to remove grease and road grime. Dove into the carbs to find a couple of stuck float needles. Freed them up, gave them a few twists and hit them with a bit of oil. Put them back together, and decided to perform a carburetor exorcism. Begone, Spawn of Satan!!!!
POOF!
Heh, its magic!!
Got a new fuel line, and a small filter I will attach. Gonna pop over to the hardware store and get a little cover for the second carb. Hopefully, I can get them reinstalled in the next week or so.
