BTW, while the carbs are off you might want to go through them and renew the o-rings and clean them out if it has not already been done. The carbs NEED to be surgically clean and sealed with fresh o-rings or the bike will not run right. You also need the stock airbox and exhaust or the bike won't run right either.



Good luck.

You waited 40 minutes without getting a thorough answer to your question? What an outrage! You should write to your congressman about this.

It must be the age gap. I am a biology teacher and this summer I have taught/proctored several online independent studies. When students want me to activate their exam, they usually txt me instead of calling me.If I don't txt back in about 30 seconds, I'll get 3, or 4 more messages in rapid fire until I get back to them.

 

[bigburto5]

i do have the stock air box but the exhaust is aftermarket, and sorry i didnt mean to sound impatient haha. im just usto faster responses from other forums. and thanks nessism, thats exactly what i need to see..

You are welcome regarding the link. BassCliff has a lot of great instructional information on his site. You would do well to bookmark it.

You did not comment regarding the method you used to clean the carbs, nor whether or not you replaced the O-rings and rejetted to adjust for the exhaust. As a science teacher I trust you understand the consequence of shortcuts in a technical process and have taken the appropriate steps to do the job right the first time.

Good luck with getting the bike back on the road.

Hi Mr. bugburto5,

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************
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:
http://thegsresources.com/gs_carbrebuild.htm
***********************************
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.

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.

Mr. bigburto5,

You'll find that most of us here are a little older than your average forum members, meaning that we have jobs and families and other responsibilities. We don't hang out on Myspace and AIM all day while talking and texting on our cell phones.

There are many original owners here, meaning that they have owned their bikes since they bought them in the '80s. They know them like the back of their hand and they are very generous with their knowledge and expertise. Be nice to them and show respect. They will teach you how to become a better motorcycle mechanic and a better motorcycle rider, just like they've done for me.

Thank you for your indulgence,

BassCliff

nessism, the pipes were installed in the late 90's and that was when my fother had the carbs worked over so im sure the proper jetting procedure was taken when the pipes were installed. the only reason the bike was taken off the road is because of a charging system falt. im hoping a new stater will fix the problem. i sat for about 6 years and im going to try to use "cream" to try to renew the inside of the tank. im really wondering if i should just try to get a newer tank that is in good shape.

and to basscliff, thanks alot for the information and the greeting. this seems like a great forum to be part of.

 

[BassCliff]

Hello again Mr. bigburto5,

Yes, this is an excellent community. I'm glad they let me hang around.

If I may, I would strongly suggest reading The Stator Papers (link in your mega-welcome) so that you can gain a good working knowledge of your charging system. There is an excellent troubleshooting flowchart to help you diagnose all the charging system components.

How rusty is the inside of your tank? Clean it as well as you can before coating it. Search for the "electrolysis" procedure. It's all the rage. There are also acidic solution washes with rattling chains and roofing nails and such on the inside to scrub off the rust. Happy wrenching. Keep us informed.

Thank you for your indulgence,

BassCliff

i will have to read up on the charging system for sure...

the inside of the tank is really bad. i was going to try the acid solution, and then a coating of this stuff called cream that a friend told be about. but im not sure if its worth saving. i made a wanted post on here for a tank. hopefully i can find one....

im going to work on getting a few pictures up of the bike tonight if i can find the time...

 

[80GS750]

i would use either the kreem stuff, or the stuff made by POR-15

either one is very good....

If you indeed have a CHARGING SYSTEM problem...and many of these bikes do, then a starter is the last thing you need to worry about. If your Father parked the bike for this reason, you'll need to go through ALL of the connections, clean them well and grease them, and then do the proper checks as stated in the stator papers, to ensure that you've covered all the bases. As for the carbs, I'd pull them apart and at the very least, spray some carb cleaner through all the passages to ensure that everything is open. O-rings from Robert would also be a good call.

Just out of curiosity...how old are you? The good folks here will help you out and then-some, but you do have some responsibility to do all the "required" checks first, as in many cases...you may be able to help yourself. Basscliff's welcome and web site will cover everything needed to get the bike up and running.

Take your time and do things correctly, it just may save you the 40 minutes that were "wasted", in regard to your original post.

yes i did mean stator, sorry for the confusion, and i am 21 years old. i do plan on taking all of the step in checking the charging system. before i came here i didnt have any type of manual for the bike so i was just going by what i have had problems with in the past on a few smaller engines i have worked on. but now that i have a procedure to fallow that is what i will do. and sorry for the crapy spelling. i just try to go to fast on the keybord and my fingers just do what they want so i do apologize haha

 

[bigburto5]

so if i wanted to set up a make shift fuel cell to make sure the bike runs brfore i spend a bunch of money on a newer tank, what would be the best way to do that. i tried before but couldnt figure out what to do with the vaccume line on the #2 carb. anybody know how i could pull this off??

thanks
