Who wants to buy my junker

So I build my vac sync.
Seems to work perfect on the table.
Do as Rick said in a post I found, clean the YICS port.
Plug the YICS port with a tshirt piece soaked in marvel mystery oil.
My first idiot mistake - not leaving a bit of the cloth outside the port.
So now THATS jammed in there. Will take a long socket extension and a hammer to get THAT out.

Vac sync. Nearly sucked the fluid right in. Lines were about 5 feet long.
Idle is still way the hell off, won't idle right.

The more I screw with the vac screws, it goes back and forth between idling better and idling worse, and when I get the idle good, I hit the gas and it nearly dies then it revs up and takes forever to slow down. Sometimes I get the revs to come down nice and quick, but it nearly dies at the bottom and the idle is off.

SO! Who wants to buy this thing right now, $1500. Otherwise I think I might just roll it out into the stream out back and piss on it.

People who don't have the right tools should just stop. Period.
No vac sync, made one. No YICS tool. Made one.
Truly an idiot, and the bike needs to DIE.

You probably can't tell, but I am a WEEEEEEEEEEEEEEEEEEEE
BIT

Frustrated.


Just a lil.

I actually SPANKED my bike with a ratchet.
I think it liked it. :evil:

Gonna sleep REAL crappy tonight!

 

Are you lettin her Idle long enough when she's idling good before you rev her? And when it takes forever to come down I think that means she's good and warmed up and you should let off the choke! Calm down buddy! Dont wanna pee on a peice of history now! Thats like Yamaha Blasphemy!

 

We all have days like that...be careful with that rag in the YICS port. It might be better to pull it out with a pair of those medical type pliers shown in the valve adjustment thread. If you try to force it through you might just pack it in tighter.

A couple of weeks ago, I was blowing hoses off the engine while trying to sync the carbs. Quit for the day and things sorted themselves out a couple of days later when I started over.

Hope things go better when you start fresh.

 

Here's an idea; someone tell me if it's worth anything or not.

For the initial sync, use a vacuum gauge and Rick's one-gauge-sync method. That should get you in the ballpark.

Then use the fluid-based gauge to fine tune the sync.

 

Get 2 pushrods, Ford or Chevy, and a hammer, and beat the wadding thru.
Now, did you make BAFFLES for your 4 tube Manometer??

Bafflels keep the levels from jumping around and if you were way off, all the fluid would suck into one carb really fast. Is that what happened???

Start over- - keep at it.
Did you read those 3 links I sent you ???

quote- - And FYI - I get the hint... there are a lot here.

 

alright man think about if you sell this bike do you really want to sell it or do you want to get it running and feel satisfied that you go it running. i know if i sold it before i was satisfied i would almost die over it. i would regret it for the rest of my life.

so take a breath and go watch some tv or something come back another day. does it absolutly have to be running NOW? im a pretty impatient guy but my bike is now in 400 plus pieces. build it slow DRIVE it fast. youll get it done i would just wank it out the way it went in.

hope you get it

 

ok had time to calm down.
I said to the bike 'jamaican me cray-z!' lol.

the cloth I put in the yics is in there good but will come out.

I built the basic 2 bottle setup.
2bottles, line between them... another line from each bottle going to vac port.
they did not jump, or even rush in. they just crept more and more up the lines before I had to kill it. even at a very rough choppy low idle.

and to top it all off- I got outbid on the colortune I was buying on ebay.

can I RENT a manometer from autozone or somewhere? I need the idle cleaned up before I can colortune anyway. I really don't want the hassle of doing a bench sync... 80 hr weeks at work don't allow time for that stuff.

 

Once the bike is hooked up to
the sync tubes, I don't think you want to rev it up. I think you need to adjust all four carbs at idle. Someone please jump in here if I'm wrong because I plan on doing this in the next month or so.

 

Sounds like your rig isn't air tight.

These engines typically pull a vacuum of about 9-10" mercury (more when you rev it then drop the throttle closed). 9" mercury = about 10 feet of water. Lighter fluids like atf or alcohol even more than 10 feet. Unless your system is closed it needs to be rather tall.

Instead of screwing with the bottles just get a long piece of clear tubing, form it into a U, put some fluid in the bottom, tack it to a wall or board and hook the ends up. That 2 bottle rig is essentially the same thing with 2 jars and a lot of extra pieces in it.

Compare the level in the 2 sides of the hose. When both sides are the same height you are done.

 

Do you know for sure that your valve clearances are in spec? See Fitz's picture post in the FAQ.

Did you take pictures of your home-made synch contraption? If not please put pics in your gallery.

My intake manifold clamps were very stretched out when I removed my carbs. I replaced the clamps on both front and back of the carbs. chacal stocks them and they work very nicely.

You have an air leak somewhere. Find it.

Buy the $40 YICS tool from chacal. You have $1500 into your bike. Buy the tool.

 

+1 on valve clearances; carb tuning can and will drive you crazy if you have a tight valve or two.

Trying to jump right to vac sync without "the hassle of a bench sync" is another reason for THIS hassle. If you're not "mechanically" close to begin with it will take a lot more doing. By going right to the vac synch you're "fine tuning" without doing the "coarse tuning" first.

And I agree it sounds like you have an air/vacuum leak somewhere or your slides aren't truly free. Do your carbs pass the "clunk" test?

 

The fastest way I have found to pickout a vacuum leak is to use propane. I take my old Burnz-o Matic and open the valve and let the raw propane flood the area I think where the leak is. The idle will change or speed up. now you know where to look. I had that happen when I took the carb manifolds off. I didn't get #4 gasket in the right place and what a deal that was. I could not get that bike to run right at all. Once I found the leak and repaired it. Thats all it took to get it so I could tune it up right. Keep looking you'll find it. Sometimes its just better to go over all that was done and think if something is out of place or??????

 

sounds like you didn't make your sync tool right. the tubes going to the engine should never touch the fluid. the tube going between the bottles should go all the way to the bottom but the tubes going to the engine should stop right at the lid.
also, to measure how much fluid to put in the rig only fill one bottle to about an inch or two below the vac tubes and then pour half that into the other bottle that way even if it all gets sucked to one side it still won't go into the engine.
for a basic concept look up an aspirator.

 

As far as getting that piece of cloth out ... what about taking a small fishhook, bending the 'J' out, and using the barb to get the cloth out?

 

I was farrting around for days with a homemade sync gauge buth then discovered that you can get a really nice tool on flea bay.

This company seems to focus on these tools

Ebay Company selling Carb tune tools

 

You guys are really THE BEST.

Seriously.

First off - I think I am going to bite the bullet and garage the bike for a few weeks. Get my valve job done, pull the carbs (I am not breaking them, just basic cleaning and bench sync...) Check and clean all manifold and carb boots, check for leaks around exhaust... etc.

I will have to deal w/o riding for a few weeks. Only really have about 5 hours on each Saturday to work every week. So it may take a while.

On two other notes...
Fish hook into rag in YICS port, awesome idea. I would rather PULL on it than RAM it in harder and make it worse. So I will try that first.

ON ANOTHER NOTE... Carb sync tool. I am a DAMN fool. BRAIN FART!
The tubes going INTO the carbs... were DOWN in the liquid. I let my friend put them in the bottles. And because he got home so late from work, it was dark and I never noticed! Such a fool! But that is a GREAT thing to find out! Thank you very much for pointing that out.

I am much more excited about the bike sitting there for a few weeks now.
In all honestly, I really just vented a bit here, obviously not selling the bike or trashing it, or peeing on it lol.
Just needed to vent a bit, was pretty sarcastic (nobody laughed about me spanking the bike and saying she liked it?) lol.

Anyhow, I will post pics of my sync rig if I can convince my friend to take them and email them to me. It really is a decent little setup.
(PS, it's the two bottle rig, not the 4)

So, Once I get that rag out, I'll redo the rag (without stuffing it ALL in there so I can get the damn thing out!) And then resync with the setup made correctly! lol.

I am actually at the point that I'd rather let it sit and get it done right.
It's so hard to get around the 'I just wanna ride, and it's running ok.'

But I am there. I need to get it done and done right.
Valves, Carbs, tuned, and rear brake.
Speaking of the rear end of the deal, I got 80w90 hypoid oil @ autzone, one quart. That is the right stuff, and enough to do the job, correct?

Thank you all again for your help and keepin me 'chill' lol.
Good times!
Can't wait to see my baby fire up nice and clean. This will give me time to get that Mother's polish rubbed in real good... O_O
