help with vacuum routing and question about intake boots

[coolgoldtiger]

howdy too all. i'm a newbie on here, awesome, awesome site.i bought my first bike this spring at 37.lol.. it's a 83 gs 850 gl. i traded a beat 93 jeep cherokee for it .it hasn't ran in 8 years but one look and i fell in love.but it was kept in a garage. it has 35,000 on it.. it needs the usual things fixed. i rebuilt all 3 calipers. and the carbs. i haven't started it yet. the problom is, the guy who had it sitting in his garage tore the tank off and the air cleaner and air box. in the prossess, he took off all the vacuum lines. i have them ,but don't know where they go. i have a clymer manual that came with the bike. but it has nothing about where all the lines go. after seeing one of the post about rebuilding the carbs (thanks so much by the way, great pics ) i know one of the lines goes from the front of carb2 to the petcock, which doesn't work yet. but the rest are a mystery. i think there are just 2 more in the rear of the carbs in between the carbs and the one right in the middle which is larger is for the gas line. also when i took off the carbs. 3 of the rubber boots cracked and split. where do i find new ones. i have a used bike place near me but they might be only slighty better and as i want to keep the bike i would like fresh ones on there. any info would be great.

There are lots of places that sell OE parts: bikebandit.com, motorgrid.com, flat out cycle, etc. Bikebandit is pretty fast but spendy, flat out is cheapest but you can't be in a hurry. Don't forget to get new o-rings for the boots. And if you didn't replace the o-rings in the carbs order a kit from cycleorings.com. It's critical that the carbs have fresh seals and are clean.

Regarding the carb lines, one is fuel as you noted and the other is vacuum - both go to the petcock. The two extra lines for the carbs are vents. Just run the lines up and lay them on top of the airbox.

Check this link to basscliffs site about the lines... http://members.dslextreme.com/users/...locations.html

Good luck.

Hee Haw Howdy!

Hi Mr. coolgoldtiger,

Please visit my website (link below) for all kinds of 850G lovin'. What you can't find there can be answered here in the forum. Now here is your mega-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)!

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 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.

must be blind lol

thanks all for the great welcome\\/. this site is amazing. when i got the bike ,and found out it needed work. the first thing i thought was it was long absolete and i wouldn't find anything for it or on it. this is overwelmingly great.
i do have one question. i tryed 2 of the web sites mentioned above and can't find those rubber intake boots inbetween the head and carbs , anywhere. must be a guy thing.lol. if someone could send along a link or something . that would be great.

[Nessism]

It's hard to provide a direct link since the parts catalog is java based. You can find them in the "cylinder head" parts diagram if you go to bike bandit or motogrid under OE parts listing for your bike.

[BassCliff]

#25 and #26 are the intake boots (left and right are different part numbers). The Suzuki part numbers are 13110-45100 (right) and 13120-45100 (left). You'll need two of each. Don't forget the #29 O-rings (can be had from Robert Barr, cycleorings.com).

I just happened to reference alpha-sports.com because they use real Suzuki part numbers, most do except BikeBandit.com. For onezie-twozie parts, when my local dealer can order the part for within a couple bucks of the online price, I go that route and save shipping costs. For larger orders it's almost always cheaper to order online.

When you mentioned "guy thing", does that mean I should refer to you as Ms. coolgoldtiger? I apologize for any faux pas on my part. 8-[

OK, glad I got that cleared up. My wife is always moving stuff around on me. When I can't find it she says, "Did you look under? Did you look around? It's there somewhere."

Why not just leave it where it is?


Thank you for your indulgence,
