Carb oring mystery

[Guest]

Hi all.
i am servicing a set of CV carbs for my GS850.
I have emailed cycleorings for some new orings for the rebuild...
however, as I've been removing jets, floats and other internals, I haven't found a single oring!!!
Where exactly are the orings?
Arent there orings on the air jets and pilot jets?
i seem to remember an oring on the float valve filter (is that the right name?) But I can't get the brass housing out ov the carb body... (Is this important to get out? If yes, how the heck do I do that!!)

sorry for the (probably) oddly basic questions...
im doing this all "on the fly" and muddling through on my own here (no biker friends nearby.)

thank you all in advance for your advice and patience.

Your not disassembling them if you havent found orings........................

Well yes thank you Chuck. I'm not trying to totally disassemble them as I want to keep them on the mounting bars if at all possible...
i take it the orings are on the fuel input and breather hoses... If so, I have never had a problem with fuel leaking out of these places...
ill go and read that link you kindly supplied.
thanx again.

ok, just looked at those great photos...
yeah, the missing orings are further into the carbs...
ill strip the lot and do it right this time.
Thank you again.

There is no way around doing a PROPER job at cleaning / refurbishing carbs. You either take them 100% apart or you send them to someone that knows whats up and will rebuild them for you.

The other option is to push the bike under the shed roof and walk away. Sorry to be so blunt but half stepping is just compounding the problems. Glad to see your gonna do a proper tear down and repair.

Your right.
i know it.
many thanx.

The orings on a BS32 assembly are on the fuel rails that can only be gotten to by taking off the joining brackets. There are orings on the plastic vent tees and there are very small orings under the pilot fuel mixture screws. You will find a very small washer under the spring that provides mechanical tension to keep the screw from moving. the was is there to protect the very small oring from getting chewed up by the spring as the screw is moved. The screws initially had small aluminum or alloy caps over the screw well located on the engine side in the upper center. You have to carefully drill through these if you want to get to the screws. Unfortunately many BS32 assemblies used on GS models had the guy with the glue gun go nuts and drop glue onto the mixture screw thread. this glue is sometimes tamed by use or heat via a propane torch and penetrating oil (penetrating oil generally doesn't flame up). It takes a lot of patience to remove the screws if one or more are stuck and many times previous owners with no patience get the little caps out then strip the very shallow flat slots on these screws. they can only be removed at this point using extraction tools... some skill here is involved.

All good advice from geol above. However, unless your bike is an import, you won't have the alloy caps over the pilot screws - UK models weren't fitted with these.

I was unaware that the OP was outside the CONUS. No signature or location in post. If this is the case, I stand corrected. Suggest OP go to profile and then add a signature and location info so this won't come up again in future queries. Thanks
