Couldn't find your 10 mm washers huh? Weren't you the one behind the "where's my 10mm" wrench story too? If i were you and I ever got to Vegas, I don't think I would put any money on number 10. LOL

Stopped by the shop today to see the progress. The guy was almost done! ANother day or two (they're closed SUN, MON) and it will be done! Some interesting finds so far too.

1.The bike has a dyna ignition and dyna coils already installed (will be offering up my brand new points/condenser tune up kit to members here who are low on funds.....FOR FREE)
2. I bought all 5 control cables new, but the throttle cables were made wrong, with the nuts on the wrong side of the fitting? (what the mechanic said) so I will try tracking down a different brand for them, meanwhile, there was nothing wrong with the originals, I was just replacing them because, they're OLD.
3. Rectifier installed, the old one was bad and the plug no longer gets hot when running. (did I mention it was running on the bench, yeah, running SMOOTH and sounding sweet!)
3. POV had used green nitrile A/C o-rings in previous carb rebuild, that explains the drip!
4. remember to order connector tube o-rings when you order carb kits, they don't come with them!
5. headlight housing wiring was "customized" and is now back to normal.
6. New fuel tank petcock installed. I have rebuild kit and new screen too, so I'll clean up the old one and have a spare for the cafe project.
7. I had Iridium plugs and Mobil 1 synthetic motorcycle oil installed, with new air filter, oil and filter change.
8. I had him check the tires and rims, spokes were fine, tires nearly new, tubes and liners he said looked new too.
9. new brake pads and shoes, brake fluid flush and replacement....not done yet, guess that's what they needed Tues for.
10. Carbs rebuilt. they NEEDED it, he showed me the insides last week, GUMMY in there! One float was chipped, but not compromised yet.

He said the shocks on this seem to be newer progressive type shocks, VERY clean, but they look kinda like the originals to me (after checking the manual, the original shows three points of adjustment, the ones on my bike have at least 6). It looks like I may get to ride as early as next weekend!
Now I have to keep looking for that cafe project frame (and title)!

Awesome! It won't be long now!   "Customized" ha ha

Got the bike back today. Disappointed. The guy who worked on it actually is an old timer who works at the Honda dealer and picks up extra money at this shop (bonus!) but when riding it home, it just wouldn't idle....and every time I downshifted coming up to a light, it would die. Engine seems to stumble a little when running (it did before) so maybe he didn't quite get the carb parts thoroughly cleaned out enough. I also had a drip from the petcock lines, but there were no clamps on them, so that's an easy fix. Anyway, I knew it would go down like this, as the former owner of many old cars, I know once you fix the big stuff, other little things show their weakness. We'll get it sorted out soon enough. The shop was afraid I'd be mad, but no, I expected other problems. Thats part of owning a very old vehicle. The most important part is it is most of the way done now, and it won't be long until I can trust it on long(er) rides. :)

[TOOLS1]

I would be upset. Are they going to fix it?

[slownugly007]

Whered you end up taking it?

[MarkPBG]

Yes, they are going to make it right. He worked on it for two days and admits he may have missed something. :)

[MarkPBG]

I brought it to Powersports of Palm Beach. The old bike tech is a 55 year old guy who works at Honda during the day, and he's been a motorcycle tech for over 25 years. He picks up extra income at this place on the side....mostly the older bikes the dealership won't touch (i.e. anything older than 10 years).

[shinyribs]

I'm sure they'll get it sorted out. Probably something very minor. Old timers rock!

[MarkPBG]

Yeah, that's what I told 'em. He worked on it all day for two days, Hell, I would miss something if I looked at something that closely for that long. You need to step back sometimes.

I hope they do sort it out and it's simple and quick, I'm on a week long vacation starting Monday! (I was going to install my kitchen, but with all the overtime I've been slammed with, I was not able to meet with the cabinet builder often enough to pick out stuff and make design choices. It will have to wait until the October vacation. )  :(

Well, the mechanic rode it for about a half hour today, and it runs great, but he cannot get the idle to smooth out. Sometimes it dies on him too, unless he holds the throttle just enough to take up the very tiny bit of slack in the cable. Not enough to open the throttle, but just enough to stop that play you sometimes feel in the grip. He did disassemble the carbs completely during the rebuild and clean out all the orifices, he knew about the problems with cleaning these carbs, because he's had two CB's in the past himself. (gotta love getting a good mechanic that knows a thing or two about your bike).
The shop did make me a good offer...he's going to adjust the cable so there's no slack (even though there's a tiny bit usually) and if he can't get it to idle right even then, they offered to get me a set of new carbs and sell them to me at cost (saving me almost $250). That's something I wanted to do anyway, but on the cafe project. Looks like this bike may end up as a cafe after all, can't afford new carbs for two bikes! I may just take him up on that offer. New carbs sounds like a good thing. I can always sell the old ones too.
Hoping to get it sorted out by tomorrow. Either I'll be taking it home, or ordering carbs. :)

Book calls for 1/8th of an inch play.  I suggest you turn the air screws (on all four at a time )out a quarter turn at a time until you find the sweet spot.  Mine are two turns on a 73 and it idle's fine.  There is also an idle screw that should be used to keep the idle steady.  Of course I love bliping the throttle at stops.:)

I heard that! It sounds like your getting closer,Mark. You must be a patient man. I wouldn't dare fuss at the shop,but I know I would be whining if i were in your shoes. I'm terribly impatient when it comes to things like this. But older machines are good for trying your patience.

[MarkPBG]

I may try that when I get it back, just to see what happens. :) Thanks.

[MarkPBG]

I've learned that patience gets me big discounts. He's not charging me for trying to fine tune a set of carbs that may be too old and worn to fine tune at all. Plus, he's only had it a couple of weeks, and the shop was fairly full up when I brought it in, so the fact that he even made time to work on it is good for me.  I have a car, and plan on getting a new bike too, so it's not like I NEED this one running, but I WANT it running. :)

[shinyribs]

It's funny how the WANTS can out weigh the NEEDS on the patience scale.

Patience no longer needed. I picked it up today, and while it still has a slight miss (carb adjustment?) and idles low when cold and high when warm, it runs GREAT and doesn't die at every light or when downshifting!
Power comes on STRONG and SMOOTH with just a touch of a miss. At idle when cold the tach reads 1500 but it sounds more like 750, it's lopey. When warmed up the tach reads 4500, but it sounds more like the engine is between 2000 and 2500. I know the tach is shot, or the drive gear, either way I have a new one of each after I get this idle thing done. (I may just put some new CR's on it, or the shop has a brand called (sudco?) available). I know the CR brand, never heard of the other.
Had it up to around 110 and it was solid. Pulled 3 wheelies without any trouble at all.
The only major problem now is I had the brake system flushed, new stainless lines installed, and new front pads and shoes installed. The front brake now squeals like there's a bit of pressure on it. I may have to find a spare caliper, do a tear down and complete clean and rebuild, and replace mine. It may be piston sticking time for the original caliper. :( (It's a very minor squeak, the brakes are not locking up and I can push it easily when in neutral, and the squeak goes away as long as you keep a finger on the lever.)
ANyway, to me, it's 95% done as a cruiser, but not even halfway to a cafe. :)
I rode it about a half hour today, and now I'm charging the battery as it was down to 11.51V earlier today after all the starting and stopping.
I just noticed something while it's sitting here parked. The rubber boots between the carbs and the head have nothing more than regular automotive type wormscrew hose clamps on them, they are not the correct clamps that can put a lot more pressure on the boot....maybe my idle problem is just due to an air leak!?
I'm ordering a set of the correct clamps now and will try that first. Couldn't hurt, need them anyway.
