Airbox Removal??

[kamelman]

I wanna start of by saying that I am new here, but I have been reading alot of info and I think this is a great site.
With that outta the way, I have just recieved a pretty beat up gs550m. I am currently starting total dissassembly to remove rust and re-paint the frame.
Is there a way to get the airbox out before taking the motor out? there are 2 screws under the carb side attaching the 2 pieces together can't seem to get to them?
Thanks

If you have the two peice air box then there should be two clams that holds a rubber seal joining the two halves.

The one nearest the air filter part of the box should come off the easiest. It could be that the PO has rounded the screw heads. How far haev you stripped the bike so far?

Is it like this?

[kamelman]

No it's a little different. the side that connects to the carbs goes all down the length of the airbox with 4 screws holding it together. The top 2 no prob but the bottom 2 can't really get to.
Here's a pic

Hee Haw Howdy!

Hi Mr. kamelman,

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************
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:

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.

Thanks for the warm welcome. Do you know what the little electrical box attached underneath is?


Here's a pic in it's current state of disrepair. I plan of having it finished by next spring, but I get a little obsessed and who knows maybe even by the fall.

[hampshirehog]

Never seen a box stuck under there before. I'm guessing the PO might have stuck maybe the box for an aftermarket electronic ignition or the like down there.

[kamelman]

I'm not sure myself. It does look stock as it does plug into the main wire harness and there is no patch work. I'll post some pics when I eventually get it out

[BrianMcDonald]

I managed to get a screwdriver on the two bottom screws holding the airbox to the chamber where the air cleaner goes - it takes some doing, but I did manage to get it removed. The carbs were off the bike at the time. I had to do it to get the right angle on the intake manifold pipes (which were flaking).

My bike also has a heat-synced "thing" attached underneath the air cleaner. On mine ('82 550L) it's an aftermarket igniter of some sort. You can see the wires coming from the right side cam cover (where the signal generator is) to the "thing" then up to the coils.

[kamelman]

Thanks everyone. Finally got it out. But now I'm dreading puting it back in.
