I've been thinking about/talking about/trying to find a way to get this sonuvabeesting home for about the last 3 or 4 years, and finally got the opportunity this weekend. It's been sitting in a concrete closet inside a steel barn in east Texas, so on the surface it really isn't too bad considering it's been sitting about 10 years. Unforutnately, when we left it there 10 years ago it had about a half tank and a carb full of gas. All in all, not too bad for free! Free never lasts long though, I'm already compiling a list of things that need to be replaced, or at least cleaned up. If anybody has any leads on parts or wants to chime in with pointers or advice, I'd be happy to hear it! Anyways, everyone likes pics, so here ya go..... 1971 CB100, in all its glory!

Quick question: as I know these dinky little old carbs can be had cheap (knock offs mostly), does anyone know of any model carbs that will bolt straight up? For the price of a rebuild kit, carb cleaner, and a new set of floats, I may as well just pick up a new unit right?

Flying J · « **Reply #2 on:** July 12, 2011, 04:35:16 PM »

Here is my take on the carbs. I dont know of anybody who has done a swap or what carb is a direct fit. Even if you found a carb that fit would it have the correct jetting for your bike? No. Will anybody have any idea? No. But you do know that the stock carbs worked, and you do know the exact jetting required for said carb. So it may be tempting to buy a $30 carb but in the end you will likely be buying the parts to fix your stock carb. END RANT.

now i have purchased a carb kit for these bikes and the only things that i really needed was the bowl gasket, and maybe the idle adj. screw. The main jet is the wrong size, the needle is the wrong size. So my suggestion is buy just a bowl gasket and clean everything else. At least that was my experience with the 125s. Once you have the carbs clean, adjust the valves, points and do the timing. Then they usually fire up.

looks better then the parts bike i had picked up.

Gotta love those baby CB's!

+1 on cleaning/using stock carb.

Good Luck........

Haha thanks guys. And FF, I wasn't disregarding the info you supplied me yesterday, just reaching out to see if anyone had a quick/easy/cheap remedy (I know, I know, you get to pick one or two, not all three!)

Flying J · « **Reply #5 on:** July 13, 2011, 08:20:57 AM »

No worries, if you find a different/cheaper way im all ears. If you want to be the guinea pig on one of the new cheap carbs I say go for it. I would love to have an alternative to the $$ honda stuff

Coyote13 · « **Reply #6 on:** July 13, 2011, 01:19:28 PM »

Anyone have any insight into the batteries on these little dudes? I'm going to keep the 6v system, as this is going to just be a little 'round-town-putter. However, I would like to switch over to a solid state unit to gain a little flexibility in mounting. Thoughts?

A bit over the top.

Ahhhh just a bit! Man that is pretty sweet though, thanks for the link. I'll see if I can find something a little less spendy with similar specs. On a related note, I ordered up some gaskets for the carb and am looking for some fork seals, should have those ordered tomorrow. Also have a POR 15 three stage kit coming in, should get around to that this weekend. Truckin' right along!

Flying J · « **Reply #9 on:** July 13, 2011, 11:07:07 PM »

Fork seals from honda are 8.91 each. Is there a honda dealer near you? The after market ones are cheaper. Do you know how to take the forks apart? Do NOT take the bolt out of the bottom like you do on a 550 or 750. I believe all you have to do is take the top cap off, remove the clip that holds in the fork seal and then you yank on the fork lower like a slide hammer and drive the seal out.

Coyote13 · « **Reply #10 on:** July 14, 2011, 06:52:59 AM »

That sounds entirely too easy. My local dealer doesn't have the fork seals listed, I'll have to go back and look again, or maybe give them a call. I'd imagine they were unintentionally left off the site and no one ever ordered any or noticed

Coyote13 · « **Reply #11 on:** July 14, 2011, 07:29:20 AM »

Ok so I took a look at the dealer's parts fische again. Part #28 should be the seal, unless I'm loosing my mind, and the parts listing at the bottom goes straight from 27 to 29. I checked CMSNL and it's the same case there. What gives? I really don't mind paying 9 bucks for NOS fork seals, but I can't find the part number in any of the fische listings. FF, do you mind telling me where you found them?

Flying J · « **Reply #12 on:** July 14, 2011, 07:57:16 AM »

71 & 72 are basically the same bike. I just used the part number for the 72. Make your dealer look it up on the 71 parts fiche just to make them crazy. Then tell them to try the 72.

Coyote13 · « **Reply #13 on:** July 14, 2011, 08:03:55 AM »

Hahahaha never waste a perfectly good opportunity huh? I think I'll give them a call right now!

Coyote13 · « **Reply #14 on:** July 22, 2011, 09:24:51 AM »

Hey FF, I'm having some trouble getting the slide pulled out of my carb. Tried spray cleaner and a little PB Blaster and the thing won't budge. Do I need to pull the needle set and clip out first or should it all come out as a unit? The throttle cable has been completely snapped off, so that's no use. Any suggestions?

MoMo · « **Reply #15 on:** July 22, 2011, 11:31:56 AM »

Use a heat gun to warm the body, you should then be able to work the slide up and out. There is probably a bunch of gunk between the slide and body, the gun will loosen it...Larry

Coyote13 · « **Reply #16 on:** July 22, 2011, 11:44:34 AM »

Thanks Larry, I figured heat would be the next suggestion. I don't have a gun, but I've got access to one so I'll see if I can get a hold of it.

Flying J · « **Reply #17 on:** July 22, 2011, 12:54:21 PM »

He is right. Heat is what does the trick. You could try a hair drier if you have one. I have no hair so i bought a heat gun at harborfreight.

Coyote13 · « **Reply #18 on:** July 22, 2011, 02:10:15 PM »

Yeah I shave my head regularly, never really needed a hairdryer. Got a buddy with a heat gun though. Happy Friday guys, stay tuned, should be more coming this weekend

MoMo · « **Reply #19 on:** July 22, 2011, 02:33:33 PM »

Makes 3 of us, no hair either but not by choice

Coyote13 · « **Reply #20 on:** July 23, 2011, 10:13:53 AM »

Hell, I figure I'm gonna lose it eventually anyways, might as well get comfortable with it!

Coyote13 · « **Reply #21 on:** August 03, 2011, 08:56:11 AM »

Ok guys, the carb is clean, unstuck, and almost ready to put back together. This brings me to my next hurdle: electrical. I need a new battery, the old one is toast for sure. I'm going to be running no side covers and instead am going to make an electrical box to fit between the frame rails, probably 2.5-3 inches deep. In doing so, I's like to use some type of sealed battery so that I can lay it on its side inside the tray. I found this little guy while searching the net for anything that isn't 200 bones (this is supposed to be a super-low budget build). I realize I would have to change the connectors on the bike, but do you guys see any problems I might run into with this battery?

The link is broken. Im going to guess that its a safety light battery back up. I was told by a guy at "the Battery Store" that it would not work well because its not designed to discharge and charge the way a motorcycle uses a battery. I went with the $140 shoria battery. Not cheap but boy is it small and light.

Coyote13 · « **Reply #23 on:** August 03, 2011, 09:08:09 AM »

Mr. Moore you are out to destroy my budget aren't you? What is it that I need to be looking for in terms of charging/discharging? I mean, how is that rated?

Flying J · « **Reply #24 on:** August 03, 2011, 09:41:20 AM »

I wish i could tell you. That was all the info i got from the guy. I was looking for a small sealed for my 125 but i was looking for 12v. I went with this one. The expensive battery is for my 550.

took on the task and came up with this....TaDAAAA
