Man, they really do look alike, don't they?

Wow...

[Steve White]

they are certainly similar although I much prefer the Moto Guzzi appearance wise. Perhaps both firms farmed the design work out to the same design house or maybe the designers for the two companies attended the same school or worked together or something. Definitely next generation stuff.

That is EPIC!!!!!! WOW!

Shameless plug: My new '02 1200 sportster, traded my '51 chevy for it. S&S carb and intake, straight streetsweeper pipes, runs freakin awesome! for sale $4400/OBO

Some more goodies:




Broke the f'n tap off in the other side. Going to see if they have any tap extractors at school.

You'll see more of these later. I'm going to put my rear sets in place of the passenger footpegs. I still need to figure out which bearings I'm going to use, then I can wrap up the design.


Started her up for the first time since she's been home. I need to go through the carbs. Guess this might be the reason:


All's well with the #1 carb; everything else is stuck. I have no idea how it started.

[V8Transporter]

Nice work! And the whole 'Orgainic' thing you're doing with the carbs is just facinating.

[Turbo Punk]

Damn fine work Fungus!!!

IIRC, J T Nesbitt did the design work on the Confederate.

[fungus]

Cleaned out all the little ports and orifices, freed up the needle valve springs, gave the bowls a good cleaning and replaced some hardware and the lines.

P.S. 3/32 brazing wire works perfect for carb float pins.

[JiI]

I'd want this!

Oh, one of those old things? I think I have one sitting in the corner of my shop. It's the Deluxe Red one and has twin turbos, I think.

Congrats on getting it running, also congrats with hippie in the video not stealing your bike.

Make sure you turn down the idle as it seems way too high. Aim for 900-1000rpm. Sounds like a winner though!

Is that clear tubing for fuel? Please tell me it's not. If it is, the fuel will harden the tubing and cause it to crack with vibration... believe me, I know. Kragen sells metric fuel line in little clear boxes by the hose clamps. Use it if you can find it.

Now get that damn murder-on-wheels going already!!!!

[V8Transporter]

Nice! Makes me want to run out to my Seca, pull the carbs for the unteenth time and find out what the **** is up with #1's low speed jet. Did you say you put in carb kits? Where did you get them and what did they come with?

That usually happens to me as the bike sits on it's kickstand, which tilts the bike to the left, and any particles floating around will end up in that carb. Anytime my bike would run like crap during a ride, I'd pull the idle jet from carb #1, clean it, and the bike would run like normal - perfect.

Hippy??? Where???
I'll be tuning the carbs and such once I finish extending all the wiring (soldering it, I really don't feel safe with a bunch of crimp connectors) and pick up a battery. Unfortunately I'm having trouble figuring out the battery bypass capacitors... I'll play with it more some time down the road.

Yep! That most certainly is clear tubing for fuel! It's the only thing I could find that would clear between the carburetors; conventional lines have walls that are too thick. It's meant for fuel line on lawnmowers, so it's rated for gas. I'd love to get some metric line though! Even BikeBandit.com doesn't carry metric lines. The SAE lines just don't fit right. I don't like the idea of cinching the clamps that tight. We don't have Kragen down here, but I'm on the hunt for some. This will work for now.

Side note: asked a local import motorcycle shop if they carried metric fuel lines. They said no, that they used SAE vacuum line.

No, unfortunately Honda changed something in their carburetors in '77; the carb kit for a '73-'76 is somewhere around $17. For the '77? $80. Plus shipping. I went through and cleaned everything extremely well, and reused the parts. The bike only had 4k miles on it, so even though everything was frozen up, it's not worn much.

I plan to buy a set of '73-'76 carbs some time and build them correctly over time, then throw 'em on later.

Right now I have an issue with carb #3 overflowing randomly... acts almost like something is sticking...

Side note #2: Cutting out lower brake caliper brackets on the CNC machine at school right now. It's going to be a 3 bracket system for each caliper.

[V8Transporter]

On the carb front....I found Z1 Enterprises in my latest copy of Motorcycle Classics and gave them a try. Kit with new needle and seat, float gasket, and a couple of o-rings was about twenty bucks, so I ordered four... Needle and seat only at a couple of other places were about the same price. Could be the difference between OEM and aftermarket...but the photos looked good.

[fungus]

Yeah, if I could get a decent set for a decent price, I'd be all over it. Nothin' doin' though. They're pretty proud of their '77 kits.

Battery dilemma... as I mentioned before, I removed all of the starting system, and now I'm trying to figure out which battery to use. Considering that I no longer have to turn a starter motor over, I would think that I didn't need much of a battery at all... However, some guy on another forum said that he wouldn't use anything less than 9Ah on a starterless CB550???

Stock battery was 12V 12Ah. According to the other guy,

I don't remember amp draw of coils, probably 2~3mps each?
with lights and generator 5a/hr isn't leaving any reserve.
It's electromagnetic not permanent magnet
Charging doesn't really start until over 2,000rpm.
You don't try and use electric starter?
It's going to draw about 40amps when turning, probably closer to 60amps initially.
For kickstart only you probably want at least 9a/hr

I'm trying to fit a maintenance free battery in the void left by the starter, and I've found three that will "fit". The one that fits the best is 2.5 Ah. Then there's a 3Ah and a 4Ah. Anything bigger and it won't fit in this spot. Ideas?

[fungus]

A few of you guys with SOHC4 Hondas may find this helpful. Once you remove the starter you have a big hole in the middle of the case. Plus, the starter cover bolts to the starter.



I made this to plug up the hole, and the little hole in the top could be tapped to bolt a new cover to.



I say "could" because I'm probably going to machine part of it off so that I can fit the battery in this slot. I was originally planning to leave this spot open so that I could store some small tools in there.

As for a battery bypass, if you haven't been in the battery thread, no bypass system can be used (sparx, mighty max, etc) on the SOHC4's because they need a power source to excite the magnet in the alternator. I'll be working later on making a permanent magnet stator. I just need to get her on the road right now.

Repaired the headlight ear that the tap broke off in. Ground out the tap, milled a slot, milled a steel insert, drilled/tapped a couple holes and voila, good as new.

After a shitload of measuring, brainstorming, calculating, designing and finally babysitting the CNC machine, I came up with these little guys:




Now to design the top bracket.

If anyone wants measurements or patterns, just let me know. Blazing the trail on this one.

[Turbo Punk]

Awesome work Fungus!!

[V8Transporter]

Very nice, or 'tasty' as the Brits might say.

[Unkl Ian]

Pretty sure I saw the second on at Kreater Cycles a couple months ago.

[V8Transporter]

Apehangers have never been my 'thang,' but the bikes look like fun. Is that a chopped snowmoble in the background? You guys chop and bob 'em up there, don't you?
