a thank you to all past gs 550 threads

[adamzuka]

so after four months my 78 550 is running! it took a bunch of reading, testing, work, and learning but you all made it possible. and for a 400 dollar investment was a great way to get into bike repair. the only problem i am still having is coming off a dead stop on a hill. have done a thurough carb clean, new plugs with good spark and voltage, cleaned the tank and petcock, set the carbs to factory. juat curious what is the best way to go from here to solve this it will go up hill but i have to rev it up and feather the clutch. no real problems on flat or downhill just uphill from a stop

Is your problem that the bike dies, or what? My recommendation is to not set to factory specs, but to add just a bit to the fuel and air pilot screws for a better idle mixture.

Did you also sync the carbs? Assuring that they are pulling the same amount at the same time will do wonders for off-idle response.

Sounds like either the carbs are still dirty or the gas tank has stuff in it plugging the petcock screen . Did you purge the fuel tank and the fuel line when you cleaned the carbs?

 

[adamzuka]

ill try that later today steve

cloud changed the fuel line and purged the tank the flow out of the petcock is great. thanks though man

Greetings and Salutations!

Greetings and Salutations!

Hi Mr. adamzuka,

Here is a bunch of information for your reference, whenever you may find it necessary. It's your mega-welcome! :dancing:

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)![FONT=Arial, sans-serif] [/FONT]

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 In The Garage section via the GSR Homepage 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 if your bike uses shims for valve adjustments, send an email to Mr. Steve requesting a copy of his Excel spreadsheet that helps you keep track of clearances, shim sizes and other service work.

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

***********Quoted from Mr. bwringer************
Every GS850 [and most other models] 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:

1. Intake O-rings (install NEW OEM or Viton only - common nitrile O-rings will quickly deteriorate from heat)
2. Intake Boots (install NEW -- these cannot be repaired)
3. Valve clearances (more important than most people think)
4. Carb/airbox boots
5. Airbox sealing
6. Air filter sealing
7. Petcock (install a NEW one)
8. On '79 models, install new points or Dyna electronic ignition (or at least verify that the old points are working correctly)
9. 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.
10. Stock exhaust with NO leaks or holes -- good seals at the head and at the junctions underneath.

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:

OEM Parts/Online Fiches:

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://denniskirk.com - Put in your bike model and see what they have.
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.
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.

basscliff all that info is way handy. thanks much man.

steve I went one turn out on air and 1/2 out on fuel and it totally solved my problem thanks man.

this bike has been so much trouble i've done the carbs as per the guide here. had to re do all the wiring because the "owner" before myself had totally buggered it and it caught fire. the valves were way out of spec. the plugs were bad and plug wires were going to the wrong cylinders. the points were original. the intake boots leaked as the o rings were bad. the brake fluid looked like burnt oil. the tank was full of sand come on sand man. so after all this I have a 600 dollar runner that has picked up the name lazarus lol

serious thanks to all of your here I now know my bike inside and out. I can't count the hours i have spent on this forum reading old threads and tweaking a problem or two I am now a gs'er for life

damn this sounds like my bike. How did you do the wiring? I'm in a complete rebuild and I know I could use help with that part of the process.
