OK, I know how bad Motorcycles can "burn" one for cutting corners, that saif tho, I need one ride to beget another....

Be gettin' the parts to get the damn other rigs fixed or ANYTHING. Living a full two miles from a country bus line that runs 7am to 7pm sometimes (if they feel like it), sure does suck!

The other option is my rage-a-holic neighbors and landlord, who all drink 24/7 or are apt to. Being the ace scoot jockey I am, I prefer my chances I spose....

Maybe I waited too long this year, IDK, but when the motorcycle went down I have spent days gettinga b bicycle back up, for NEED be rif=ding, but it's too hot during day now.

I will add my living situation is rustic, I must haul all my own water.....

OK so long story short, I have an '85 (CA model I think, charcoal can inside air box)?

Anyway this is an old, "twice gifted" machine that I assumed had been worked on, it has not. IDK if the carbs have ever been off. The vacuum lines had been butchered to bypass the charcosl can, and in the heat on second ever oil change, I rather severely overfilled (1/2 quart) Didn't seize it but got fluid locked till I got that right, overflowing the bowls and almost catching bike on fire.


Turns out the PCV vacuum and one of the two on the intake side of the carb also lost it's plug's seal was sucking wind, casing fuel issues. I worry about the PCV, not sure what it was connected to if anything (at work now can't look).

Anyway I got the carbs off and normally I'd tell anyone to just go through it. Thing is, I know it runs as it, and I NEED a runner.

I'm guessing just plug the two top lines again and the bottom to the PCV will be fine. I will drop the bowls and check the floats since they're accessible, but I think if I need to not lose transpo and have it asap for temporary that this should work fine (till I can make a manometer and fully clean everything).

I worry if that PCV might be plugged. I see I can get one for like $25 that I don't have. Is there a generic that can be made to work there or can I do a temporary work around?

Thanks in advance.

Is English youe second or third language? Not a lot of what you typed makes any sense (to me at least.)
You need a manual or at minimum the Honda carb manual (generic for all thier carbs, should be able to find a free download) California model almost certainly has 3 jet carbs, PITA to work with on anything other than a stock air system

Yeah, just as I figured, not much help here.

I NEED it to run even if it blows the motor, it's worth it. I'd just assume it not seize or catch fire is all or rocket a bolt from the case

Now if anyone wishes to be of help, I'd appreciate it. Thanks.

Sometimes doing more than skimming, sneering at what ya think ya read and then telling me exactly what I said I don't have the time or abilility to deal with might get a better reaction you'd think anyway right? Sorry if it breaks someone's heart I destroy a machine. I'd prefer not to die of thirst or inability to get groceries and to a pharmacy.

Thnaks for the non help tho.

My life is INCREDIBLY complicated, boring and not your biz, I just need a runner now, IDC if it dies sooner than it should otherwise. Sorry if that doesn't jive with some folks opinion of what motorcycles are. They are both things of beauty and real LIFE OR DEATH trans[po in some parts of third world America and the rest of the world.

Sorry, just really going through it on all fronts.

The problem is that we can't answer a question we can't decipher or understand....Therefore we need to ask questions back....

While I am unfamiliar with the California model, (never saw or had to work on one), there is a breather separator assembly in the air box shown in the fiche...Is that what you mean by "charcoal canister"?...

A PCV valve is basically a (one directional) check valve...You MAY be able to clean and reuse, I don't know.......

What "bowls" did you overfill with oil?...Only way I can see "fluid locking" the engine would be to fill either the cylinders or the sump with liquid.....

I get what you mean about getting it on all fronts, lots of us have been there to one degree or another. I don't know what you've got to work with other than a 450 Nighthawk. Be careful, take a few extra minutes here and there to prevent little mistakes like overfilling the oil. Better to be 1/8 inch low on the dipstick than 1/8 inch too high, plus oil left in the bottle will get used eventually right?

So what shape is the bike in, is it complete? Just needs some key areas cleaned up like your carbs?

There are corners that can be cut, you can run with scissors and not worry too much. PCV valve? What the heck for? It'll run without it, just vent it to the atmosphere like previous generations of Hondas do.

You may not need to rebuild your carbs. They probably just need certain areas and passages to be clean. If you can spare the cash for a cheap can of carb cleaner, it may be enough if you use it sparingly. Cotton swabs help but a stiff bristle of hay will work well for free.

Please go through your bike one system at a time, let good enough be good enough and move on to the next system. If you can post pictures please do so. But try to focus on one area, system or even one part at a time. If you've got only a matter of days to get it running we can help but it may take a lot of words.

Look at it this way, when I drive across town here I take the short route through some not so nice neighborhoods. There's an old dude with an 1100 goldwing, I pass his house every couple of days and when he brought his bike out this spring the windshield was broken, he said some snow had slid off the roof onto his covered bike, ouch. I drove by it for weeks like that until today I was going through a bunch of parts I'd bought last fall and there were 2 windshields that looked right. I was never gonna use them, and they were pretty scratched up, but you should have seen his face when I brought them over and said the word Free... That made it all worthwhile. Us Honda guys have to stick together.

So when you're not sure what to reply or how to answer someone, just take a minute more before getting grumped up and read again, not all things we'll reply with are meant to get your grumpy up.

You can get that bike running, we can help. Sometimes members here have shared parts with other members, you never know who's gonna come through for you.

So pick an area of the bike to start on, and don't be like me... Keep it short and to the point. :D

Its gonna be ok.

Everyone's life is incredibly complicated, your not that special. I got laid off 16 days after arm surgery then found I had fractured spinal disc, both from work accidents - so what? 8 yrs later, still no money or chance of it. You don't know me or need to care. All you said was bike isn't working, it may have been working sometime but your not sure? You have internet access, download service and carb manuals, probably free here or DTT?, You will need them to work on that bike even if you intend to destroy it in next week or so (although it is a pretty reliable engine if you just keep oil in it reasonably clean and change filter sometime). If it's your only transport you don't **** with a running vehicle unless you know you can fix it or make other arrangements for a day or two, been there, learned that the hard way. Do you have tools and resources other than duct tape and JB weld?

And thats not just sarcasm, i looked in his previous posts and he's got plenty of years turning wrenches at dealerships, and not just for Honda.

So dont take it the wrong way, it just could be an uphill struggle.

markjs,

If you're still looking at this thread and not totally disgusted, PLEASE allow me to try an explanation. There are some incredibly knowledgeable and talented guys here. More importantly, they are knowledgeable about OLD HONDAS in particular! Don't give up too fast. My first suggestion is to stop using text message-style abbreviations. It overly complicates the issue. I'll assume you're using a phone and I'm sympathetic to the space issues in that as opposed to a computer keyboard & screen, but it really hurts how your question comes across to those who really do want to help.

Bike problems can be incredibly frustrating! That frustration is multiplied when the bike is needed. Please try again. Re read what AlanF posted above. Whatever the problem with your bike, you are unlikely to find a more talented pool of help than you have available here. That help however is totally dependent on you. You must provide information they can get a mental picture from to suggest solutions. That may entail repeated back and forth questions and suggestions! It's a process of elimination basically, starting with the most likely, or easily addressed cause and working backward until solved.

Best of luck.

I guess that explains a lot. I've never sent a text and don't have a cell phone (being on call 24-7-365 kinda makes you hate cell availability, when it was no longer a work requirement II dumped it)

I'm waiting for that day myself, I've been on call going on 15 years, 5 months, 15 days, and just a hair under 19 hours.

Edit: For those who've never been on call, watch the first several minutes of Apocalypse Now where Martin Sheen can't unplug from the job and it makes him just a wee bit edgy.

It took me at least two years to begin sleeping without being conscious of everything going on around me - while I was sleeping. Those nights (or days!) I'd lay in bed for an hour then finally give up on trying to go to sleep only to realize I was asleep the whole time were spooky.

Weird as that sounds to those unaccustomed, I get the impression you understand. I still get in that mode now and then and waking up and realizing I wasn't already wake, is even more discerning today. And yet, when I wake up after being totally soundly asleep, completely unplugged and unaware, somehow it's even more bothersome. :-?

While that does sound weird (and my wife often says she hears things as if she's not asleep despite my hearing her lightly snoring), it would be even weirder at this point to see the OP actually post in his own thread now... intelligibly, of course

LOL, that really is hilarious.He's probably so pissed he won't be back for a while? For anyone who hasn't been on call 24/7, if your not a doctor/medical, police or firefighter it's never(?) a matter of life or death, usually just money involved. I was repairing construction equipment (although one site was paying about £50,000 / $80,000 an hour renting a machine)

While I don’t have much to add, I appreciate this background. This could be in a novel.

I hope we hear about it if it is. Would love to read the chapter about the arrogant vintage Honda fanatics!

OK well I'm sorry I had to step back there.

First off, I do know what I am doing to a large degree. I have quite a bit of general 80s Honda MC experience, even including previously owning this same model.

The carb is in functional state other than the floats, all plastic and non adjustable are warped and uneven by long sitting and then being run like that and later with a vacuum leak making it really bad.

The only ideas I have are replacement (not maybe economically viable ATM), lucking out at the wreckers (a very real possibility), or heat gun manipulations?

Anyone have any ideas? No apparent holes in the floats, just they were forced into a state of wrong over time, one, I think it was the high side is darker in color.

I've always just used parts floats, being as the 80s CV carbs from 900s and 750s were abundant enough and interchangeable in the past.

I want this going, but I am not willing to wreck the floats if a little care could save them.

Welcome back Mark! We thought we'd lost you. Hope you don't mind some of the innocent fun had in that regard. :-?

Anyway, I'm not much help. Not familiar with your particular model or it's specifics. Once others realize this thread is a live request for help again, I'm confident someone knowledgeable of your problem will step up. In the meantime, is it possible for you to post a photo? THAT would go a long, long way in giving us a better idea of what you're up against!

Once again, welcome back. Glad you reconsidered.

As far as plastic goes, the heat gun may work wonders. Just keep a cool bowl of water next to work, so you can cool parts quickly. I just did this repair to my sons CM400C. The front upward bracket on the dreaded right hand cover.

I've never worked on all plastic Honda/Kei-Hin floats. Every set I've worked on has a stainless steel strip joining the plastic parts. Suzuki used all plastic/nylon from early/mid 80's, what a PITA. Distorted floats won't be a problem if someone can come up with the fuel level you need, Honda never gave a spec though so it would have to be a direct measurement. You need to remove the vacuum piston tops and check under the removable piece/slide piston guide to make sure that doesn't have dead bugs in it (or live ones, very common in my experience) The pilot jets are pressed in, you have to be very careful with a pliers or vice grip and pull them out. holes are only about 0.012" diameter (35~38 jet) You already know carbs are very similar to those on CB750/900DOHC, what works for those works for 400?450. You will probably have to sign up at a 750/900 forum as they have a much better following/modification due to Superbike and Endurance racing in the 80's. You can disconnect all the EPA/CARB stuff and plug the holes. Being a Cal.) means you will have leaner jetting than the 47 state bikes If someone doesn't come up with Euro or Canada jetting I'll see if I can find it. It will probably be worth drilling pilot jet to about a 40, either a 0.40mm or number 78/79 micro drill (works on all the 400/450/750/900 carbs) Doing that will give some adjustment on fuel screw rather than the 4+ turns they usually need
