My toasty winter project

Thanks, I'm waiting to hear back from a friend who has a friend that might be able to do it. But if I don't hear back from him I'll give you a shout.

Oh and what's "nine o eight- 4910"?

 

Perhaps it's a telephone number?

 

ahh, that makes sense. He's in my area and that's not a prefix I would recognize for around here so a phone number didn't click in my head. But with cells phones getting all sorts of number now it's hard to keep straight anymore.

 

Another good parts day. Got the carbs, wiring harness, battery box, and rectifier/regulator in. Fixed a few rough spots in the harness, and the carbs are amazingly clean. Or maybe I'm just biased against the ones I had.

Now as far as the carbs go. This set is from a 750 J. What all would I need to change over to make this set work on my bike?

No actual bike work though, too much rain.


Eatatjoz: I'm sending a PM regarding the tank and TCI.

 

I believe your going to have to swap the jets...

 

Fuel jets should be #110 mains and #40 pilots for a 650 Max.

Air jets should be #195 pilot and #50 main for 650 Max.

Jet needles should be Y-10 for a 650 Max.

Those are the changes needed to convert a set of 750 carbs to a set for a 650 Maxim. The 750 carbs should already have the #40 pilot fuel jets in them; all of the other items (jets and needles) would be different.

 

Okay, just a minor update. Working on getting the new carbs cleaned up and out. Started cleaning up the top hats a little. First step was wet sanding with 400 wet/dry. Gonna work up through 1200 then start polishing.

Before:


After:


Sorry for the grainy pics, I'm still using my cellphone since my wife got me a blue tooth dongle for my laptop for christmas. I'll get a proper camera when my excess aid comes in though.

 

Get them Clear Coated ASAP. I did that to mine and just waxed then and after a couple of months the Oxidation cane back and I'll have to pull them and redo them to get them shining again.

I may abandon the idea of doing them that way if I can find an Industrial Coating that will look good and take being washed and left outside for dew to form on them without deteriorating again.

 

Oh yeah, they'll definately get clear coated. I'm just getting them all cleaned up and nice looking first. I may even paint them, I don't know yet.

 

Ok, I've got the carbs all torn down and ready to be cleaned. I had little trouble at all getting the mixture screws out and they looked like they'd never been touched. The No.1 carb hat was kind of a pain to get off because the screw were ate up quite a bit. I'll have to find some good ones.

One of the bowl gasket came apart, but the others are still intact. And you can see one of the hats that I'm trying to get the chrome off of.


If I understood Rick's guide, there's supposed to be a spring, o-ring, and washer in the mixture screw hole, but all I got out was the washer and spring. Did I just miss the o-rings?

Edit: nevermind I got em out. They were just WAY down in there.

 

your definitely going to have to post pics when this project is all said and done.....

 

Here's the above carb hat hit up with 800 then 2000. Looks pretty good I think. Just need to work on it some more though, then polsih it out and coat it.

 

I made a tool out of a Very Large Safety Pin ... heating-up the end and putting a slight right-angle at the end to reach down in there and extract that O-ring.

Its a SMALL O-ring ... actually about the size of this font [ O ] .

You need to hook it and bring it up and out. Keep an eye on it ... if it gets away on you ... wave Bye-bye!

 

Yeah, I got them out. There safe and sound in a little zip lock bag with the other too small to see on the floor parts. Carbs and bowls and innards are soaking in carb cleaner now.

I did find out that I'm going to need a pilot fuel jet, the air jet that goes in the middle hole (not the one that closer to the motor), and a needle. The ones in the 2nd original carb were trashed.

 

Ryan, I should have all those item, let me all the items you need and we can put together a care package for you!

 

Thanks, I got your last email about the brushes and what not. I'm just trying to see what else I'm gonna need so I can make as few orders as possible.

 

Don't soak the Body's in a harsh Carb Cleaner that might do damage to the Throttle Shaft Seals. It won't take long for those Seals to swell-up and become useless in there if the Carb Cleaner isn't rated safe to rubber parts.

 

They're not, I just sprayed them down real good. Got in all the passages and holes. It got dark on me, but I'll go more into depth on it tomorrow.

 

I see you've unbolted the carbs from the mounting rails ("breaking the rack" I think they call it). I seem to remember reading that it was something to avoid, if possible, as getting the carbs back together with the same spacing was difficult.

Is that the case, or is there little to no play in the mounting holes, making it easier for the carb bodies to line back up? I've got mine off the bike and disassembled (polishing up the piston bores), and if it's not too difficult, I'd consider breaking mine apart. That way, it'd be easier to check all my throttle shaft seals, or at least clean up the outside of the carb bodies.

 

Over the years I've tried a few things to prevent losing a C-clip or a Sync Screw Spring.

My latest and possibly my best idea yet is to use a Kitchen, white, plastic garbage pail liner.

Slip the Carbs in the bag and undo the Clips and Springs.
If they get away on you ... you ain't got far to look.

"It's in the bag!"
