quick carb dip question

[greg78gs750]

hi all, a quick question, do i need to disassemble the carbs to dip them? the directions say to remove all the plastic bits, but i wondered about the floats, or anything else inside that berryman's might adversely affect. i will be taking them apart anyway, but thought i would dip'em first to clean them up....thanks!!!!

All the plastic parts have to be removed before dipping because the Berrymans will destroy plastic and rubber. Leaving the "O" rings in place could result in bits-n-pieces of them becoming lodged in the passageways. So, I would say, its best to remove all plastic and rubber before dipping the carbs which means you must disassemble everything completely prior to dipping. You cant leave the jets and emulsion tubes in place anyhow if you want an effective cleaning. The only way to clean the emulsion tubes is to remove them, visually check the spray bar orfices and clean them manually anyhow.

Also, if you have not already, order an "O" ring kit from robert Barr at cycleolrings. Dont even consider reinstalling the old rubber "O" rings.

Yup. :-D

Before you dip them make sure the pilot screw caps and the screws themselves are removed - Suzuki pressed in a cap after adjusting the screws at the factory to you need to drill it to remove (very easy).

i know i am new here, and i have said it before, but i will say it again, this forum is AWESOME in terms of support, information, and tolerance of stupid, easy questions. thanks again!!

For drilling the pilot screw caps............. The caps are thin aluminum plugs and the brass pilot screw heads are aprox 3/16" below the caps. If you punch a drill bit through the cap, it will immediately destroy the slot in the top of the pilot screw. Drill a 1/16" hole in the middle of the cap, preferebly using a battery drill and going slowly so you do not "stab" the drill bit through and into the pilot screw head. Once you have the hole drilled, take a hand screwdriver and thread a #6 screw lightly into the top of the cap (just enough to grab the cap) and pull the cap out by the screw you just threaded into it.

Hey howdy hey!

Mr. greg78gs750,

I don't believe I've ever given you the "official" unofficial welcome post. Here ya go!


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>**********
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.

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.

aww, thanks bass cliff, i have been shuffling my feet around in the corner for a while waiting to catch your eye.....

well, i have the carbs completely disassembled, labeled, and ready to dip. all went smoothly, i even got the stuck/mangled drain screws out with a little dremel action...

the choke tube in one of the bodies is bent a bit from the po, or someone, but it was working fine before, so im not going to worry about it.

as for pictures, well, i have a lowly (and sucky) dial up connection, and i havent had the patience to upload ANYTHING. even checking my email is a struggle. but when i get some high speed access, i will show you mine....god knows i've seen plenty of yours...

i should open a thread on my plans for the winter in some other place, but i want to be able to show progress, and i am slow. but photography has been happening, so, soon.

i have printed and pretty much memorized the carb cleanup for my vm's, this along with my serendipitously discovered clymer gave me the courage to tackle the carb project.

i have also already soldered all my electricals, per advice given here, and run a ground directly from the reg to the neg battery pole, which had the effect of solving my charging problems, thank you very much.....

my wife cringes every time she asks what i am doing and i answer "looking at motorcycles".....so i think i am well on my way to being a gs junkie.

thanks again for everything, im sure you will get plenty of my obvious questions in the future!!!!!
