The project is dead! (see last post for details)

This is going to be my version of JustinL's Scout thread(I now love scouts).

Checklist

• Clean it
• Drain sludge from gas tank
• Change the oil
• Rebuild and clean the carb
• New cables, their all bad
• Clutch Lever
• Bend the shifter so it can actually shift
• New tubes
• Rewire the whole thing(I think rats got to it)
• Bondo
• Primer
• Register
• Insure

I'd love to have one of those and I lived in town. Just take it to school real quick and not worry about parking.

[Jishory]

yeah cause you can ride those in the classroom and shit like the fonz

[super_Chris]

In between classes I pulled the seat/gastank and cleaned the thing up with some simple green, almost no grease anywhere on it. The electrical on this is ridiculous, I'm gonna have fun pulling the ignition out and making it keyless(I know that no one is even going to bother stealing it). Tomorrow night comes the carb.

I bet the cool factor the the 100 is the same as when the fonz jumped those trashcans and ate shit too.

[super_Chris]

Rebuilt the carb. The back tire still holds air for some reason, and the front can hold for almost 5 or 10 minutes, so I'm set till it's at least running. I also changed the oil and am now waiting on a clutch lever and cables.

Dirty carb.


Clean carb installed.


Overview of the slightly stripped bike.

Are you just leaving the wires in as little place holders for now?

Pretty much. I'm not even messing around with the wiring until the bike is running.

Damn it, I need a clutch lever and a cable, if I had that the bike would be running!

[Justin3]

Thats the same carb that was on my 87 dirtbike and it was hell tryin to clean it out because the dude left the fuel in it for 4 years I I let it soak in chemtool for 3 days and replaced the float, then it worked like new.

[shrugs*]

I have a lever for a pre-85 cb750/cb1100-- ordered the wrong one after I dropped my CB750S.. think it'll work? Hard to tell from the photos.

Love the bike, btw.. Daddy wants one.

[super_Chris]

We attempted to push start it today, and nearly positive that it's not getting spark. We tied it to a truck and kept forcing it into gear driving up and down the street. It gets great compression, and the gas is making it all the way to the carb, and that is sparking clean on the inside.

Restatement, the electrical is pooped, and I'm somewhat lost. Anybody have a wiring diagram for this bike(or similar honda)? Anybody have any experience finding faults in bike's electrical systems?

Look at the fucking rats nest going on here.

[Scooby]

I would get some tape, and run each wires length separately, noting what it does on a piece of tape around the wire.

Pick out essential vs non essential wires that way and work from there.

That whole ball of wires goes into the headlight, and appears to be later routed from there. It looks as if Honda made it more complex than it needed to be, probable on purpose.

Still looking for a diagram, you bastards better help me find one!

EDIT: I forgot how to spell.

[Scooby]

I don't think diagrams existed back then. :P


Good luck.

[ninefivezero]

Cool project man, keep us updated.

[BrentN]

The only rewiring of a vehicle thats doable without professional education under your belt is a bike, thats the good news. The bad is that without a wiring diagram you're gonna take forever.

I would NOT be surprized if haynes has made a manual for this bike. Search through google, you may find something.

This looks like a totall kick ass little project, I would love to do the same thing heh.. Wow, I actually want to go look in the paper and see if there are any junk bikes like that that I could fix up. Find a p.o.s. for like 50$ and put some quality time into it.
Those older bikes are built so well, I'm not surprized whatsoever that you still have good compression. As long as you have that, its worth fixing.

good luck my man.

[super_Chris]

I just got a hold on a wiring diagram for a similar Honda CB100. I found it via a completely unrelated post on another Honda forum. The site has diagrams for a bunch of different bikes, if you guys need help on your bikes.

The site is very low brow as far as design. Obviously someone with little fancy HTML design, but it works. Old Man Honda, wiring diagram section.

Hopefully I'll be posting in the next couple of days about this.

EDIT:Where the hell does the black wire going into the ignition coil originate?


EDIT2: Scooby, I was looking at your bike, and the wiring looks perfect. You might get lucky and only need to clean the tank, petcock(how is that fucking spelled?), and carb, and have a running bike.

[Scooby]

Fuck, that would be awesome. I mean, i'd love to get it running then re-run the wires if theyre all working.

Im sure it could probably use a new battery too. Have you checked yours?

The battery in the bike I'm working on now is definately dead.

Also, if I were you, I wouldn't even bother re running the wires on the 400, they're perfect. Your bike doesn't even have a battery.

EDIT:I was hoping to be able to get away without having to rewire the entire bike, but whoever worked on this thing prior to me didn't know what they hell they were doing. They made solder joints everywhere! Also made sure to use a liberal amount of the wrong color wires. Yup, I'm gonna have fun with it.

[super_Chris]

I rewired the bike(minus the lights) and it still can't get spark. So that means that it's either the generator/points/coil pack or something around there. I refuse to spend any more money on this bike, which thus far was only wiring.

The project is dead! Who wants a 100? Free for pickup.

[hans5849]

i'll take it, how long would you hold it for because i have no where to work on it right now.
