ChewedFood's slightly skewed rebuild

[cowboyup3371]

Unfortunately you made your pictures so small I can't see them. Sizing at 800x600 is about the best thing and then putting them on Photobucket allows for us to click on them and view them separately if needed. Can you say what the labeling reads? If they are what I think they are, they'll go on the t's between the carbs.

EDIT: After going to look at your profile and albums, yes they are for the fuel tees

[Steve]

thank you, I did not even know you had to pull the choKes!

Evidently you have not yet read the carb rebuild guide.

Click HERE for your own copy.

You make a good point so I pulled them up and sprayed the holes with canned air. You can see right through the holes. There wasn't really an appreciable amount of gunk on them, either.

I believe your stock main jets are 117.5. Even just a little bit of gunk on them will reduce their size to 115, 112.5, 110, who knows what. You can NOT go by looks.

Just keep in mind that for every shortcut step you take, you may have to remove the carbs one more time. Just how much do you enjoy that task?

After I put the float bowls back on, I realized I should have taken them out and really scrubbed them. It's been eating away at me so I will do it. Also, I'm gonna break them apart and clean in between really well. No point in going through all this to not do it 100% right.

If you are going to do it "right", be sure to follow the guide that is linked just a few lines above this. "Scrubbing" the bowls is not enough, you need to SOAK them to make sure the "choke" pickup well is clear, then spray some carb cleaner through it (wear your safety glasses), followed by some compressed air. As with most things in the carb rebuild, the problems are not in places you can see or reach, they carbs need to be soaked in a proper cleaner (not a floor detergent) to dissolve all the built-up gunk.

Aaaand this is where I need help:


I do not know where these go lol what is the inlet valve? Petcock?

Don't feel bad, we need help, too. What happened to the nice-sized pictures?

Can't see the pictures very well, but I can answer your question: the inlet valve is the one that is opened and closed by the float. It is the "fuel inlet" to the carb.

I don't have any fuel T's lol

[Steve]

I don't have any fuel T's lol

Do you have your carbs separated yet?

OK, there is only one actual "fuel T", but the o-rings go on the transfer tubes between carbs 1&2 and 3&4, as well as the vent Ts between the same carb pairs.

I'm telling you, there are no T's

There are just tubes.

What is wrong with the ones I have posted? Are the too small? I was posting them with that method then I went back and changed them all to the size they are now because I thought they were too big.

[cowboyup3371]

Ok so looking on the fiche shows they are just hose so I apologize for misspeaking when saying they were tubes. Did you get the orings from Robert Barr at cycleorings.com? If so, what we were telling us true for most other sets of BS carbs.

And yes the last set of pictures are too small

Yes, I got the rings from Robert Barr. So helpful!

And yeah, I thought they were bigger. I posted them the same way as all the other pictures, I don't know why those ones came up smaller.

I got up super early to go buy some stuff and ended up buying a whole lot of stuff!



And now my storage unit is getting too crowded!




But I also got these done. Almost. One of the pieces on the choke bar is backwards so I need to fix that.

Protip: When you buy SS screws from a box, make sure they all look the same. I ended up with a few that have smooth sided heads instead of textured.

also, an interesting note: The fuel hose that connects the carbs doesn't do anything. The holes are solid. I put new hose in there anyway to make it look nice but I'm curious about their function.

Hmm? Post a up a pic of what you're referring to exactly. The silver tubes connecting the carbs are not solid. They distribute fuel to the carb bowls from the single fuel line tap.

The rubber hoses, they go onto what look like tubes built into the body of the carbs but the tubes end at the edge of the carb body that they protrude from.

[cowboyup3371]

How about posting pictures that specifically show what you are referring to?

[SVSooke]

The brass tubes on #1 and #3 carbs are the vents.

[ChewedFood]

Sorry, I have been on deployment on a submarine for a while. The tubes I am talking about are the tubes that have rubber hose on them connecting carbs 1&2 and 3&4 in the picture posted by SVSooke and you can see the actual tubes built into the body of the carbs between 2&3 because those don't have a rubber tube connecting them.

I have finally got a shop sorted out and finished my YZ project so now I can dedicate time to the GS. Unfortunately I still don't know exactly what the end product is supposed to be. That won't prevent me from rebuilding the engine though.


So here's the filthy motor that has been sitting for ten+ years. Probably a mess on the inside, right?


Considering that the oil all looked like that milkshake oil on the camshaft journal bearing , this engine looks great!


I dropped some dirt into the bottom end when removing the head gasket. Good thing it's going to get thoroughly cleaned anyway. The cylinders are smooth as silk, no corrosion. All that muck is from outside the motor.


Again, could be worse IMHO.


And just to give y'all an idea of my shop that I am so proud of! There's my YZ 450 in the background that I just got back together and took to the MX track next to my favorite dirt bike ever: KTM 530. Such a great machine.

I'm looking into options on the swing arm and front end. I can't make the old ones work. I hate them too much.

I thought I would be painting the motor but the paint on it looks really good still after you wipe away the grime. So it looks like a crank bearing inspection/possible replacement, rings, valve job, and a lot of cleaning for the engine for now.
