I am going to try leaning the bike to the right side and work the penetrating oil down in there for a couple days and see if that makes a difference.

You can pick up an impact driver for cheap at Harbor freight but then go to Sears and get their bits.
Personally, I only half believe the "in-store" stock status notices at any of the major retailers web sites and will go physically look instead. However, that can of Berryman's that you spend $25 on at Advance or Auto Zone will typically have a basket in it to help dip the carbs and doesn't need to be discarded after the first run. You can save it for future use.
Needle nose vise grips or vise grips will also cracks those screws loose sometimes too. Then you can proceed with a screwdriver.
If you knew /had the tools to cut a slot in the screw head then it seems like you are pretty handy at wrenchin.
Get these screws out so we can see some bike building!
Watching post.
Thanks
x2 on the vise grips for those last two screws
The pilot fuel screw tip looks to be broken off in your photo. You better check the carb body to see if it's broken off in the body.
The foam seals are gone from the air filter frame and presumably the airbox end caps. Using high density urethane foam on the air filter frame works well, and a softer open cell foam on the airbox end caps is a popular solution.
Agree with the others that a can of carb dip is greatly preferable to those kitchen chemicals you are using. Hope you are not soaking the rubber parts and trust you are replacing all the carb O-rings during the rebuild.
Yeah, I am disappointed with the results. I didn't notice any breaks, but I will inspect closely. Thanks for that.
I read the airbox thread on BikeCliff's site that mentioned using weatherstripping to seal the caps... Is there any way to fix the or effectively seal the tear in the "snorkel" ? (I posted a pic of the tear in the boot)
Also, I am unclear on where you are suggesting I add the high density urethane foam... Could you be more detailed on that one? Thanks!
Okay, thanks for the info and pointing out the fuel screw. I clicked the link and I see where it would show up. I'll take a look when I can get back to the carbs.Hardware stores sell closed cell polyurethane foam strips that you can use to replace the deteriorated foam from the air filter frame. I think you will want the 1/2" or 3/4" wide stuff that's about 3/8" tall. You may be able to use similar on the air filter box end caps if you can't salvage the seal that's already provided.

Also, applying plenty of heat to that bottom screw, soak, heat, tap tap with a screwdriver and hammer, soak heat and hit it with vice grips should get it. I'd personally put some opposing screws back in to offset the tension as well. Might just be in my head but if you remove all but the last one (especially that bottom one) it doesn't want to come out nicely.




Hell yeah is right - nice work! Great photos too, lots of detail, nice and sharp too, thanks for that. Have you looked at the parts fiches online for your bike to see if the washer was doubled up? I don't recall there being 2 stacked washers, seems like Suzuki would've just used one thick one as opposed to 2, maybe someone else can ID it's location.
Is that waxy looking stuff inside the rotor hard or soft? Almost looks like it could be residue from the epoxy melting and recombining. Not sure on that.
Even though you don't have a battery right now, if you have a meter, you can at least use the resistance (ohms) setting to check to make sure none of the stator legs short (have continuity) to ground.
Also, if you do end up replacing it, I wouldn't try to remove the 3 stator JIS screws without a JIS screwdriver or an impact screwdriver. They are always in there super tight with locktite and will strip out easily. It's hard to get even heat or a drill down in there to remove stripped out screws. Put it in a vice if you can, and the impact screwdriver at Harbor Freight is only $8. The tips are pretty soft, but you can get a good set at Sears once you ruin the HF ones.
Good luck, hopefully someone can help with the washer and that strange substance.
