So, much less of an update than I would have hoped.  I've basically done more part cleanup, painting, and sourcing new stuff.  I do, however, have a few more questions...

  Given the condition of all of the aluminum parts on the bike (i.e., corroded but not pitted), I did some calling around to some different polishing shops in town, and the lowest quote was $600 (+/- $50) to have all the aluminum engine parts and the hubs done.  However, the polishers said it would be best for me to remove the bearings before giving them the parts, as they'd likely end up effed up, and having them replaced afterwards could mar the polishing.

  On the way home, since I had the parts with me, I stopped by a local bike shop who said it would be ~$25 to have the front and rear bearings removed, but that some of the parts (especially the front hub seal retainer) would end up a little mangled.  They asked why I wanted to remove them, and I told them that it was because I'd just been at a polishers', whereupon they asked me why I was going to have them polished (I believe the actual phrasing was "Why would you do that?  Do you have a friend who is a polisher?").  The mechanic also said that the bearings were in great shape, and it would be a waste of money and time to replace them.  They suggested covering them with duct tape to protect them, and not having those areas polished -if I go that route- as no one will see them anyway.

The long and the short of it is, since I'm going for as nice a bike with as low a budget as I can (done uni, no job as of yet), I'm torn between having the parts polished, then clear powdercoated, or clear anodized, (which can apparently be done with a home kit), or just having a go at them with a brass-bristled brush on a bench grinder, a Mothers' power ball, and polishing cream.  Unfortunately, for the moment, the bike will likely spend more time outside and I'm concerned about the upkeep of the aluminum, regardless of whether it's polished or not.

My goal is to have a bike that looks good/cared for, yet has (relatively) minimal upkeep.  I'm not against cleaning/polishing periodically with something like Never Dull, and even removing the aluminum bits to be stored inside at the end of the season.  I'm wondering what the best route to take is, as I want to keep costs down yet not have to redo work later down the road.  For instance, I certainly don't want to leave the hubs as is, and lace them into a new rim with new stainless spokes, knowing that I should've done something while I had the chance.

On another front, I also went through the parts list/diagrams I found on this site, and made a listing of all of the fastener sizes/types, and dropped it off at a shop that specializes in exactly that.  I'd like to go with stainless steel bolts everywhere I can, while treating the threads with an anti-seizing compound to avoid them binding in somewhat permanently.  Is this a bad idea in some areas?  Why?  I've read enough to realize that this is can-of-worms territory (as well as polishing - and oil, but I haven't got there yet!)  None of the bolts I've come across have had any strength markings, and I've read here that stainless steel has a lower strength/can be more brittle.

The shop was unable to get everything together for me by closing - apparently the guy who told me it would be no problem, and didn't realize how much time a list of my magnitude would take ;) - and are now closed for the long weekend.  I had hoped that I could at least get the engine mounting bolts so that I could the engine back in the frame and start installing all my painstakingly painted and cleaned parts.  No such luck... I'm starting to realize that maybe I set myself a bit of an unattainable goal for the time frame I've got over here, but I am glad that I got a lot more stuff done here than I would've been able to do at home!.

Finally, I'm thinking of trying to get my hands on a full gasket set, likely from Vesrah.  Has anyone used them?  Is it indeed a 'full' set, including stuff like the shifter seal, kick starter seal, etc. or is it just the major engine stuff?

Wow, a huge picture less post and a ton of questions!

Well, I've done some more working and (more importantly) thinking.  I realized that while it would be nice to have nicely polished aluminum parts on the bike, it really wouldn't be worth $600 to me.  They'd maybe even look out of place as nothing else on the bike would really be up to the same level.  Besides, it took ~30 years for that 'patina' to form, and every scratch, nick, and ding is part of the bikes' story/history. 
I don't want perfection, I want a bike that I'll have done mostly everything on and can enjoy.

I did some research, and decided to go with cleaning the parts on a bench grinder mounted brass bristle brush.  For the most part, this gave a finish that I really liked, and revealed that things weren't as bad as they seemed.

Next up, I used some polishing cream (Autosol), a powerball, and a dremel with felt wheels.  I finished off by wiping everything clean with a solvent and painting them with something I'd almost forgotten about - Penetrol.  Initially a paint additive to help improve the spread/flow of oil paints, minimizing the brush lines, it also works really well as a clearcoat/sealer.

Pics!:

Left side case, after wire brushing:


After cleaning/clearcoating:


Other parts:





Part of the rear hub, compared side-by-side by how it looked when I bought the bike:


The rest of the hub:



I found this pretty funny, and thought I'd throw it in.  The felt wheel on the dremel started life looking exactly like the bottom pad...  (admittedly, I had to narrow the top one with my leatherman to get it to fit the grooves of the hubs, but still).




I also decided to do some touch-ups on the engine paint, as the 'shoulders' had worn off a bit, and the top of the transmission was essentially bare aluminum.  Again, this was a brush-on product from, you guessed it, POR-15.  Actually, this is POR-20 high heat aluminum paint.  I like the finished look of it so much that the engine will definitely get repainted eventually, but I want to do it right by stripping & rebuilding while I'm at it.  For now, my immediate goal is to get to ride it over the summer.  Repainting can wait until the winter/spring off season, when I have the time and $$$ to do the job right.

Top of transmission before:


Top of transmission after:


'Shoulder' touch-up, also a good comparison shot as the light is funny in the two pics above:


I'm glad I thought to compare the pics of when I brought the bike home to today's polishing pictures, as at times it felt like the polishing wasn't doing a whole lot.  I think the results are pretty damn good, if I do say so myself.

Frankly, I can't wait until all the parts are repainted and dry, so I can start what I really love: putting everything back together again!

Well, everything important dried, and after maybe the fastest/easiest engine install ever (roughly 10 min start to finish using the on-its'-side method), this is the end result!:





Now, I'm hoping that the rest will be very much downhill!  I just have to put all my shiny parts back in, and wait for new parts to show up - which will be the most difficult part, I think.

Waiting on parts is the hardest part of any build. I'm still waiting on at least 2 parts to come in to finish off my bike and be roadworthy again.

Heh, I see you had no trouble finding the thread, Maxacceleration.  It was good to meet up with you, and I've already put the parts I got from you in a safe place until they're needed.  However, I couldn't resist putting some of them in place to see what the final product will look like  ;D

For those wondering, I met up with Maxacceleration yesterday, as I saw his build thread and asked if he'd mind parting with some of his stock bits.  This included the stock 4-1 system, seat, chain guard, rear fender, and headlight ears/signals, which are in much better shape than mine.

I also did some important running around today, and picked up all of these:

What's this jumbled mess?


Ahh, that's better...


That is (almost) every fastener needed on the bike, as well as a torque wrench to make sure that everything is done to spec.  I went through the parts fiche page-by-page, making note of all the sizes/types.  While most of it is stainless, I went with regular old zinc plated stuff for all the engine mounting bolts/footpegs on several recommendations that stainless is too brittle for any application requiring strength.

Now I can truly start putting everything back together!  However, I looked in the shop manual available in the FAQ, and it recommends putting the center stand back on first, followed by the electrics, rear fender, swingarm, etc.  I seem to have, err, lost misplaced the centerstand pivot pin.  While I look for it, or hunt down a "new" one, is it fine to put all of the rest of the bike together, and then put it on later, or will I hate myself for doing so?

 Thanks.

Well, as I've been making my way through reconnecting all the electronics, I thought it wouldn't be a bad idea to test the coils while I'm at it.

I followed the procedure as outlined in the FAQ:

1) With a multimeter set to measure continuity, the two “gazinta” wires should have continuity between the center conductor of the wires.  CHECK

2) With a multimeter set to measure continuity, the two “gozouta” wires should have continuity between the center conductor of the wires.
Mine don't.  I took the plug boots off, and clipped about 1/4" of wire off to get a 'fresh' connection.  Still nothing.

3) With a multimeter set to measure continuity, any “gazinta” wire should NOT have continuity to any “gozouta” wire. CHECK

4) With a multimeter set to measure OHMs, the two “gazinta” wires should have about 5 ohms resistance between them, give or take an OHM.CHECK

Ideally, the “gozouta” wires should have the plug caps unscrewed and removed from the ends for the above tests.CHECK


So, are my coils shot?  Is it time to justify getting a set of 5 ohm from Dynatek?

The number two check ought to have about 15000 ohms resistance.  If you truly have infinity resistance between the output wires, then it is no good.

Maybe a bit high.  But, not really eyebrow raising.  Are they the original coils?  Does the reading change when you move the wires around?

Great, I'll just re-use them then.  As far as I can tell, they are the original coils.  Moving the wires around didn't really seem to do much.

I realized that I've spent two solid days working on the bike, and hadn't taken pictures or updated this thread!

 Here are the results of todays' adventures in swearing at tools:

The first day, I got the wiring harness back in and largely routed properly.  The rear swingarm, brake linkage, center stand, inner fender, and battery box all found their way back into the bike.



Today saw the return of the front forks, headlight ears, indicator lights, ignition switch, and handlebars/switches.  I found a pair of CB400F bars, which I think look amazing as well as offer what will hopefully be a really comfy riding position (I'm 6'1" ish).  After standing back to admire my work, I actually did jump for joy at how good it looks so far (if I do say so myself!).


However, I'm stuck here:



In my haste to get the frame in to be sandblasted, I didn't take any -good- pictures of the cable and wire routing.  I've posted another thread (http://forums.sohc4.net/index.php?topic=52558.0) asking for info on what goes where.  I've got the right wiring diagram (I think the heat caused me to think that a 500 diagram would work  ;)) so it's not a matter of what connects to what, but how to make the big bunches of wire fit well with enough slack for steering, while keeping out of the way.

I'm waiting on stainless spokes & nipples from Buchanans' - I decided if I'm going to spend the money, I might as well make sure it lasts as long as possible.  I've gotten my hands on an NOS gasket set, so as I replace all the covers etc. I can fit new ones as I go.  I still need to figure out which rubber parts are still available, and place an order for them.  I also need a battery, chain and sprockets, brake pads, etc (all the usual 'wear' items).  I love how easy reassembly is when everything is cleaned, painted, and ready to go with new nuts & bolts...it's an absolute breeze!.

to make it easier you should separate the main trunk cable from the handlebar switches.  I know on 80+CBF they had a common green ground wire that ran the length of the bike.  Wish I was near you...we could definitely figure it out.  First thing to do is find you a wiring diagram.

Yeah, even with the diagram I've got that 'Bill Vaughn' provided a link to in the other thread, it's still a bit confusing.  I've got the majority of the wires in the right places, but there are parts and features of the frame that I don't have.  I'll cross post the pictures, and the same area of my bike, for reference later.

There are also two major splits (factory, not PO hack jobs) in the harness, one with about 20+ connectors, and one with about 10, but there are duplicate coloured wires in both.  I tried hooking up just the horn to see if I could get it working, but it didn't work and I don't think I've properly grounded everything out.  I'm sanding everything down right now and then applying dielectric grease (i.e Vaseline) to the connection, to make sure that it's good.

Now that I'm done this post and have had a big glass of water, it's back outside and back at it again!

razor:  it is a shame that you're so far away.  I'd love to compare to another bike, or have someone in-person to bounce suggestions off of!

Your right and left handlebar switches have their own harness still?  take it 1 function at a time.  Do you have a multimeter?  If not this is a good time to invest in one.  You first need to get it running then lights, horn, dash, etc.

To be honest, I hadn't really thought of it that way.  Once I got the etc. in place, I realised that that's exactly what it looked like.  Two 'branches' of the wiring harness.  So, I started plugging like coloured wires together.

End result?

 ;D ;D ;D

I've already mostly re-assembled the carbs in the hopes that tomorrow I can see if I can't get her to actually fire up!  This might be a little ambitious, because I need to replace the spark plugs (with only an 18mm deep socket, not a plug wrench or the much coveted special tool).  I also need to put the all of the various covers back on with new gaskets, replace the carb bowl gaskets, replace the oil cooler lines and refill the oil.

Fingers crossed!

I know it's been a week since the last update, but a lot has happened!

 In no particular order:
  - I landed a fulltime job (with crazy hours - 7am to 3pm),
  - The brake calipers on my truck seized, the replacement 'rebuilt' ones had a few issues and it took a few days for new ones to come in,
  - My spokes from Buchanans' showed up, allowing me to lace the back wheel
  - A grab rail in way better shape than mine showed up from another member here
  - A buddy in town brought in the tubes, rim strips, and Duro tires I'll be putting on the bike.   Once I've laced both wheels, he'll true them for me as I lack the proper equipment, and throw the tires on.

  Most importantly, however?

  I got the gaskets all replaced, the cases back on, oil in the bike, the carbs back on and connected to a small supply of gas, and:
  [img width= height=]http://www.imageshack.us/thumbnail.png[/img]

  IT RUNS, for the first time in nearly 30 years!  When I was playing with it trying to get it to run and giving it a bit of throttle, flames would 'pop' out the exhaust ports, and I'm sure my neighbours must have wondered what the snarling noise was...

Cool! Great find! I am a huge FAN of the CB550, as it was my very first bike! This is what I have now, a 1976 CB550F!

BTW, I have a spare set of carbs for your bike if you need them.

*Thread Necromancy/Resurrection*

  Wow, where the hell does time go?

Since posting my last reply (about 8 months ago!), the bike remains in much the same state...  This has been due to: finding a full-time job, going through a breakup, getting promoted at said job, adapting to the schedule of a working man - as opposed to that of a student - saving $$$ for parts and buying what I can, when I can.

However, I am now at a position in life where I can once again give this bike the time & attention it deserves, and am gearing up to get the bike done for this years' riding season...

Unfortunately, using Penetrol as a clearcoat on the aluminum parts has not had a really lasting effect...looking at the bike the other day, the fork lowers have begun to corrode again, ever so slightly, which now has me wondering about all the other aluminum parts on the bike, specifically the hubs.

I don't have the time, resources, or patience to lace/build the wheels myself, and so I was going to have a local shop do it.  If I leave the hubs bare, how hard will it be to polish them and try to keep corrosion from starting?  I had thought of clear powdercoating the hubs, but would have to pay a setup fee at the place I've found (they don't do clear that often), and I'd have to have the bearings pulled, powdercoating done, then new ones put in.  It also occurred to me to have the hubs powdercoated in an aluminum colour (no setup fee), but am concerned that any kind of powdercoating my chip/crack, taking me right back to square one.

At this point, I just want to get the bike back on the road for the least amount of $$$ possible, use the lowest maintenance option, while trying to get it right the first time...is this possible, or is it the classic bike version of the car buying adage: cheap, fast, reliable - pick two. ?

Once the wheels are built, I can have my Duro tires mounted, and at least be able to wheel the bike around while making 'vroom-vroom' noises! After that, it's finishing the wiring, reinstalling the brakes (waiting on a braided SS line setup), and putting all the purty decorative pieces back on.  Oh, and then riding the hell out of it  ;D.
