grrrrr... where to find new 'carb sync screw'

[shinjef]

I'm not sure if I'm even calling this the right thing, but the carbs I have are missing one of those little screws that you have to adjust to sync the carbs (the one that's got VERY fine thread).

Does anyone know where to get another one? Or the proper name for it?

Thanks

Hi Mr. shinjef,





I'm not sure if you need the "idle mixture" screw (on top/front of each carb) or if you need the "lever" assembly that's used to adjust the vacuum sync (#'s 15, 20, and 24).

There's a list of our favorite online vendors in the "mega-welcome" below. Many of these vendors have online parts fiches with exploded views making it easy to find the part you need. I like to use the Suzuki fiche at www.alpha-sports.com to find part numbers but go to other, less expensive places to purchase ( www.partshark.com is usually the cheapest ). Here's my "welcome thang". Note: All the blue type below is click-able.

Are you missing just the screw or are you also missing the spring, washer and o-ring?
I have an 80 GS550 and I couldn't find the part number on any Fische I came across, nor could any of the bike shops in town. The best they could figure was that it could only be ordered from Suzuki by getting an entire carb body.
I'd check your local salvage yard since they might be willing to part with one if they have a body that's scrap.
I did end up ordering one (a complete screw, spring etc.) through a local shop but they didn't make the one specifically for my bike and after recieving it, it wasn't exactly identical so I wound up fixing my screw and keeping the new one as a spare. I can't recall the name of the company, but it was one of the major suppliers of parts here in Canada. I think it was $7 and I got it in a few days.
So either check your local shop for an aftermarket one, or your local salvage yard.

Correct. Since the mixture screw was factory set and sealed under a cap, they are not listed in the regular parts fiches.

Mr. shinjef, if you put a post in the "Parts Wanted" section, I'm sure there are lots of these part hanging around in members' garages. Or you could call one of our favorite vendors on the telephone and ask questions. Perhaps start by picking the one close to you, like http://crc2onlinecatalog.com/ .

It's the "lever" assembly. I'll check out those sites and see if I can snag something. Thanks a lot guys!
