XS650 carb (pt.1) disassemble

[ZuluFireTrauma]

@2:16 I actually DID want to see you handle the difficult screw - that's what I'm struggling with and no penetrating oil or tapping will get it out. It's in too tight of a space to use file/vise grips (its the screws that connect the carbs - trying to separate so I can soak them). Need help.

@ZuluFireTrauma I strongly suggest keeping them together. Removing old hardware is an art, and can lead ultimately to a trip to the machine shop. You can try some heat from a soldering gun on the screw head, or tuning up the screw slot with a dremel.

Thanks for the post, I try to provide as much insight as I can and answer everyones questions, even though I haven't had much time lately because of my wife's illness.

Have you had the needles out? I'm wondering if they're spring loaded. I'm trying to figure out if they're spring loaded from above or below the clip, do you know?

[crabblike]

sorry for the delay, the needles should be held in with tiny circlips, if they're similar, there should be a plastic plug that comes out with an allen wrench(hex key)

what a s.h.i.t half a wiewing is under wiew, sorry for my english im from kazakstan like a Borat

[crabblike]

No problem, sorry about the camera angle, check out the XV750 vid, I did a little better with that one, should help with the basics.

[crabblike]

I don't know anything about Borat but I do have friends from Poland and Ukraine and it's all good!

oh man i have a 78 special with those carbs i'm a complete rookie i only took apart one other motor in school and it didnt run to begin with but i'll got to the point HOW IN THE WORLD DID YOU GET THOSE CARBS OFF THE BIKE everything is so ungodly crowded in there its almost like you would have to rip apart the whole back end of the bike out and thats insane for something that is supposed to be done ''regulary'' any help would be appreciated by the way my bike was free and it runs alright :P

[crabblike]

Start with the side covers, then the air filters, the air boxes(comes off in two halves) and you're there.

hey i have a carb off a yamaha 125 dirtbike and i was trying to get the diaphram cover off but one of the screws is so ungodly tight that its just..... idk. it is suposed to be like that?

[crabblike]

That happens over time when two different metals are together, namely aluminum(the carb) and steel(the screw). It's not actually that tight, it's in effect welded together. The way to deal with that is to spray penetrating oil on it(NOT WD-40) every other day for a week or so works the best. You may need a tool called an 'impact driver' ($25US at Sears) to get it started unless the screwdriver slot is too damaged. If that is the case then it will need to be drilled out and repaired.

hey mate, are those mikuni carbs?

[crabblike]

They sure are, unlike the Hitachi junk that I'm about to give up on with the XV920.

[inthewired0000]

thought so :)

I'm trying to resurrect a '84 GSX250 it has carbs just like that (mikuni BS30SS). Bike came with no carby so had no reference when putting a 2nd hand one back together on it and the Haynes Manuals diagrams are rubbish!

You know how theres a breather and a vacuum hose connection on the carby where does each hose go? Is it correct that the breather just goes up under the seat to keep the float bowl at atmospheric pressure and the vacuum hose goes to the petrol tank tap?

[crabblike]

Is it a single or dual carb? If it's single, then you're correct unless there's a spigot into the air cleaner for the breather. If it's dual, one vacuum is plugged(the other goes to the tap) and the breathers get connected with a 'T' fitting before going to the airbox or under the seat.(usually with a filter screen to keep insects and debris from entering the carb.

[inthewired0000]

Just what i needed to know thanks! That makes perfect sense about the "T" fitting then. Yep its a duel carb and when i got the bike although there was no carby there were still 2 pipes going nowhere just sitting up under the seat. I was always puzzled as there simply we're 2 breather ports on the carby. I'll just connect one to the breather on the carby

cheers
