72 CB750: Dolores... 5 years later, I'm back to work!

Re: Alex's 72 CB750... as cheaply as possible

Oh I suck at bondo too! I'm just sucking less and less each time I do it! ;D
So I got bored and then I got tired of looking at all that red... Then I decided to go ahead and at least spray the sidecovers. So I did, I got the black layed on... I'm going to come back with some flat silver around the edges in a few days. Looks like the tank will move in front of the wheels now... Although, that'll be more involved and include me not riding for at least a day... Anyway here's some pics of the sidecovers sprayed and on... sorry 'bout the quality but the sun was headin down fast.

I guess I need to give the motor a good scrubbing again too... damned oil leak!
 
Re: Alex's 72 CB750... as cheaply as possible

I took my tail down to bare metal, then I tried a paint scheme on my tail... It's okay, but I'm going to sand back down and do something else. Anyways, here's a couple of pics of the paint I did that I'm redoing this week with something totally different. The silver is bare metal with clear over it, and I was going to put some red pinstripes along the lines...

And this afternoon I taped and painted one of my shocks. All the original showa decals were taped off. These $22.00 shocks are starting to shape up! The other one gets it tomorrow:

It's not much, but things are (hopefully) gonna start moving a little faster. Up next is(in no particular order): Paint wheels, paint tins, disassemble and paint front end, also I'd like to sink my speedo into my headlight bezel like in the $50 mod thread. Also maybe about to start making a new seat (I have an idea that I'm working on in my head)
 
Re: Alex's 72 CB750... as cheaply as possible

More of the same stuff today. I painted the other shock and I tried out another idea for my paint on the tail. I'm liking this one maybe with a charcoal pinstripe around the border... If I end up liking it I'll do the tank in the same scheme.

Re: Alex's 72 CB750... as cheaply as possible

I like this. It's a work in progress. Ride and go! Can't wait till I start putting my bike back together!
 
Re: Alex's 72 CB750... as cheaply as possible

This is a great project. I really like what you have done with the exhaust and the shocks.
 
Re: Alex's 72 CB750... So much for being cheap!

Okay, I've been collecting parts for a while now, and the build has become a bit larger than I originally thought. First of all, my sweet drag pipes have gotta go. They look great and they sound fantastic, but they've gotta go. See, Drag Pipes are built to go in a straight line, therefore they're not built with cornering clearance at all. I've scraped the pipes on both sides during deep leans, scraping holes in my pipe wrap. I've got a 4-into-1 header and I'm going to build an exhaust tight to the bike so it won't impede cornering at all. I've got new taillights in, and I'm working on a mount for them. It's two 2.5 inch round l.e.d. taillights with a flange around the lights for mounting (pics later).
Also I've decided to bring a little bit of brat style into this bike. I'm currently bidding on a 16 X 4 40 spoke Harley rim on ebay. Two days left! I'm going to lace that rim to the rear hub with stainless spokes from Buchanan's ($$$) then lace the old rear rim to the front hub. That'll get me a little bit lower and it will also give me the big front tire look that I like. I've got the paint for the wheels (Rust-O-Leum Appliance Epoxy paint, thanks Joe!), but since I've decided to do all this work on the wheels, they won't be painted until they are laced, trued, and have tires mounted. Instead I'm going to paint the fork lowers with the paint soon.
I found a large (3 feet by 4 feet) sheet of some pretty thick aluminum, and I'm going to try my hand at hammering a bump stop out of it. We'll see how that works out.
Also I've got two oil leaks to see about fixing... I believe that they can both be handled without removing the engine. More time and more money though.
I'll try to post up some pics and progress on some of the above items in a few days. Later,
Alex

Brilliant build, I really like the schemes you've come up with for the rear cowl, amongst other things.

I'd highly recommend getting a dolly for the aluminium work, they've served me well when I've had to take dents out of my car and I can only suggest that they'd be good for forming something too. Should be a few bucks from your local automotive store and it'll save you a lot of time with a ball-pein.

Good stuff man - boingk
 
Re: Alex's 72 CB750... So much for being cheap!

I've been working on my new tail light setup today. I got a cheap set of l.e.d.s off ebay. They're 2.5 inches.

I decided I wanted to mount them like the old set, which were 2 inchers. I made a cardboard template for my mount.

Then I drew it onto a street sign. The sign proved a bit thick for my snips, so I took it to work to see what I could get done. Today I learned how to use a plasma cutter! Wow that thing is neat. The cut was very rough though, so I spent a while with a bench grinder and some files. The triangular hole in the template was not going to work with the plasma cutter, so I just drilled a hole in the middle with a good sized bit. Then I painted it and mounted the lights in it.

I mocked it up on the bike... I dunno... They may be a bit big for my taste. But safety first. The old ones were too small and not bright enough. Overall I'm happy with it. Tomorrow I'm going to get it all installed and wired. Turn signals aren't required in the state of Alabama, so they might be next to go!

By the time this bike is done, it'll probably be 40% old street signs!
 
Re: Alex's 72 CB750... So much for being cheap!

I am not so sure I like it. It looks a little odd with the two round shapes hanging out from under the tail. If you like it thats cool, but you may want to consider rivets instead of screws to hold the lights in. I think that would give it a smoother look, also try to line the holes up to be in the same orientation. Good luck!
 
Re: Alex's 72 CB750... So much for being cheap!

If you're going to have two round taillights, why not make them double as rear signal lights? I also agree with lining up the mounting screws/rivets.

Looks great though. I like how every time you post a pic of the seat, the cowl has changed!
 
Re: Alex's 72 CB750... So much for being cheap!

great work man, but it does look a bit out of place... how does it look lit up?
 
Re: Alex's 72 CB750... So much for being cheap!

Getting back the exhaust wrap for a minute, You see this a lot but I have never done it. I assume that hose clamps aren' t the only way to secure that stuff, correct? It seems like you should be able to wrap the end that you start with so that you don't need a clamo there. Who has ideas of other ways to finish that job.

I never heard of painting it but what a great idea! I do like the look of the white wrap once it has "seasoned" though, that dirty race bike look.

My two cents on your tail light is that I agree that it doesn't look quite right. What about mounting them in a rectangular frame to follow the lines of the back of the seat?
 
Re: Alex's 72 CB750... So much for being cheap!

diesel, there are some clamps that are designed for the wrap application. I used them on the wrap on my nissan 240 header. Got them from a speed shop. They work much like a stainless steal zip tie and they sit flat and flush. Very slick finish. As far as the paint goes it is accually recemended to protect the wrap. The wrap can cause rusting issues under it if it is not painted, due to it absorbing moisture and holding it there until evaporated by exhaust heat!
 
Re: Alex's 72 CB750... So much for being cheap!

Yeah the lights look a little funny. I'm still thinking on what to do about this. The lights are a bit latger than I thought they would be. As far as rivets go, the flanges on the lights are plastic and I was worried that rivets would break the flanges more easily. I'm going to paint the screws black as well and see what that does for it. I'm gonna wire the lights up tonight and see how they look lit up.
You can also get the stainless zip ties from West Marine, usually cheaper there. When I wrap the upcoming 4into1 exhaust I'm going to use those. Also someone over at the sohc4 forum gave me a lead on some cheaper spokes. More on this as I find out... The bidding is almost over on my harley rim. Found out I can run a 150 on that rim and still clear (most)everything in the back.
As a side note I'm thinking of doing a different paint scheme on the tail. ;D
 
Re: Alex's 72 CB750... So much for being cheap!

Ditch those stainless steel zip ties. Maybe there's a special technique I don't know of, but I found them to be a pain in the ass. I took them off and replaced them with stainless steel safety wire.

This stuff is great. You can use it for all sorts of stuff. Guys that race use it to lock down any piece that might potential come off during a race.

I just picked up the twist tool yesterday. Can't wait to use it.
 
Re: Alex's 72 CB750... So much for being cheap!

Here's a quick instructional video on safety wiring bolts.

Re: Alex's 72 CB750... So much for being cheap!

I think the lights would look cleaner if they were smaller.

I have a quick question about LED taillights. Would I need to modify anything to the wiring or is it just plug and play?
