Hey all, I am new here. I am trying to get my wife's bike 1981 GS550 to run. I have been doing some work on it, but now I have a question on where to find a particular part. I think the bike has a leak in the o-rings/gaskets that are between the intake boot and the cylinder. I had a great page bookmarked on my old computer and I can't find it again. Does anyone know where I can find such a part?

Thanks in advance!

Cory
 
Hey howdy hey!

Hey howdy hey!

Mr. KRISTI'SGS550 (Cory),

First of all, let me congratulate you for finding such a fun-loving, hard working, beautiful partner to share your life with. Oh, and you're wife's not bad either. :-D

But all kidding aside, let me give you the full "official" unofficial welcome...

Let it be known that on this day you are cordially and formally welcomed to the GSR Forum as a Junior Member in good standing with all the rights and privileges thereof. Further let it be known that your good standing can be improved with pictures (not you, your bike)! :grin:

Perhaps you've already seen these, but I like to remind all the new members. In addition to the carb rebuild series, I recommend visiting the garage section via the GSR Hompage and check out the Stator Papers. There's also a lot of great information in the Old Q&A section. I have some documentation on my little BikeCliff website to help get you familiar with doing routine maintenance tasks (note that it is 850G-specific but many tasks are common to all GS bikes). Other "user contributed" informational sites include those of Mr. bwringer, Mr. tfb and Mr. robertbarr.

And here are some quotes from one of our dear beloved gurus, Mr. bwringer, with ideas on basic maintenance needs (depending on initial condition), parts, and accessories.

***********<Quoted from Mr. bwringer>************
Carburetor maintenance:

Replace the intake boot o-rings, and possibly the intake boots. Here's the procedure:
http://bwringer.com/gs/intakeorings.html

Here's an overview of what happens with this particular problem:
http://cycleorings.com/intake.html

You'll also want to examine the boots between the carbs and the airbox. There's a good chance these are OK, but check them over.

And finally, if things still aren't exactly right, you'll want to order a set of o-rings for BS carbs from the GS owner's best friend, Robert Barr:
http://cycleorings.com

Once you receive these rare rings of delight, then you'll want to thoroughly clean and rebuild your carburetors. Here are step-by-step instructions that make this simple:

**********<Quote Mr. bwringer>**********
GS850 Basics:

Every GS850 has (or had) a set of well-known issues that MUST be addressed before you have a solid baseline for further troubleshooting.

It's a vintage bike, and it's quite common (as in, every single GS850 I have had contact with) that there are multiple problems that have crept up and slowly gotten worse over the years.

It's not like a newer vehicle, where there's generally one problem at a time.

These common issues are:

Intake O-rings (install NEW OEM or Viton only - common nitrile o-rings will quickly deteriorate from heat)

Intake Boots (install NEW -- these cannot be repaired)

Valve clearances (more important than most people think)

Carb/airbox boots

Airbox sealing

Air filter sealing

Petcock (install a NEW one)

On '79 models, install new points or Dyna electronic ignition (or at least verify that the old points are working correctly)

On all models, it's fairly common to have problems with the spark plug caps. These are $3 or $4 each, and often worth replacing if you're keeping the stock coils/wires.

Stock exhaust with NO leaks or holes -- good seals at the head and at the junctions underneath.

Parts and Accessories:

Put in your bike model and see what they have.

I would definitely double and triple the recommendations to use Cycle Recycle II and Z1 Enterprises as much as possible. These guys are priceless resources. Z1 tends to have slightly better prices, CRC2 has a wider range of goodies available. If you're near Indy and can bring in an old part to match, CRC2 has a vast inventory of used parts.

http://oldbikebarn.com seems to be slowly regaining a decent reputation, but it's still caveat emptor. They don't have anything you can't get elsewhere at a better price anyway.

OEM Parts/Online Fiches:

http://www.babbittsonline.com/
Decent parts prices. Spendy shipping. Don't give you part numbers at all. Useful cross-reference if you obtain a part number elsewhere. Efficient service.

http://bikebandit.com
Fastest. Middlin' prices. Uses their own parts numbering system to obfuscate price comparisons -- can be very confusing for large orders. Cheapest shipping, so total cost usually isn't too bad.

http://flatoutmotorcycles.com
Slow. Cheapest parts prices, crazy shipping costs. Don't expect progress updates or much communication. Real Suzuki part numbers.

http://alpha-sports.com
Exorbitant parts prices. Different type of fiche interface that's quite useful at times, especially with superceded part numbers. Real parts numbers. Shipping cost and speed unknown due to insane, unholy pricing.

Stainless Bolts, Viton o-rings, metric taps, dies, assorted hard-to-find supplies and materials, etc.:
http://mcmaster.com
Fast, cheap shipping, good prices. No order minimum, but many items like bolts come in packs of 25 or 50. Excellent resource.

http://motorcycleseatcovers.com
Great quality, perfect fit (on original seat foam), and available for pretty much every bike ever made. Avoid the textured vinyl -- it's perforated.

http://newenough.com
You DO have riding gear, don't you? Great clearances, always outstanding prices and impeccable service.

Part number above for the "O" ring that seals the intake pipes, you will need four. In the diagram below it is item number 23. Diagram is from Alpha Sports.

Yeah, the diagram is from Alpha Sports, but get the o-rings from fellow board member Robert Barr. Click here for info.

I'm not sure if Robert sells them. He did not have the "O" rings for my 550. He may have them for the later models. But check first.
 
Ah ha!

Robert Barr, that's the guy I'm looking for.

Thanks,

Also thank for the welcome, support and help so far. I am sure I will be back for more as i work on this bike!

As far as I can recall, the 550s came with one of three different types of carbs. Early ones like yours were smaller VM slide carbs. There were then a few years of four individual BS-series CV carbs just like the bigger bikes, then there were a few years of the two-barrel CV carbs. Cory has the middle type, so Robert just might have them. :-s

I believe I have the BS series CV carbs is I am not mistaken.
