Finally Started ( LET THE FUN BEGIN )

Well ladies and gentleman I finally decided to start on the Biatch and after removing her RACK of carbies I think she is appropriately named will let the pictures tell her story.












Have pulled all apart and are now soaking in carb cleaner :roll:
All comments and helpfull hints greatly accepted

 

UGLY! Worth keeping as a sticky to show newcomers to the site how there carbs may look before cleaning?

 

:lol: :lol: :lol: yes wasn't what I expected :lol: :lol: :lol:

 

yup, they get nasty and PO's always say, well it use to run, but im not sure why it wont start now..

 

those are pretty impressive.

 

Looks like ethanol fuel and moisture from sitting around. One reason to drain the carbs and tank when storing these bikes to prevent this from happening.

Carb soak is going the get a lot of that out but you are going to see some corrosion damage (pitting) in the float bowls. The drain screws are going to be hard to get loose too. Len at xj4ever may have some spares if you need to replace.

 

Thanks guys yes I have a feeling Len and I are going to become very close even though he lives across the pond so too speak

 

Woohoo pod filters arrived today pics later as carbs are still swimming in cleaner but I fear it is not helping her cause she might need a new rack lol

 

Just another silly question where is the bloody name put on these rack ???????????????

 

Careful on the carb soak. If you leave them in there too long the aluminum will turn black.
Those look like standard Hitachi carbs

 

:lol: :lol: cheers for that

 

crikey, I'm wondering what mine will look like when I crack them open 8O

a tip... once you've stripped the carbs, find a hydroblaster and get them to clean them up for you. They do an amazing job.

 

I am convinced that soda blasting carbs is the way to go. The soda just washes out with water. Unlike bead blasting can clogg and you might have to manually remove it.

I am lucky enough to own both a parts cleaner and bead blaster for doing small stuff but the parts washer I can boost the pressure up too skin tear this should be sufficent lol

 

Whats going on in the second pic..left carb, left air jet ?

 

When you order your parts don't forget the throttle shaft v-seals. Your's will need replacing. Also fuel rail and idle mixture screw o-rings. Skip these and you'll just be pulling the rack off again.

 

beats me never pulled anything like this apart before according to the xj bible the air jets are concealed under the hats :? :? :?

 

I agree with Bushy, that looks like a plugged air jet. Different carbs have replaceable and non replaceable air jets in different places, but that one is not like the others... Also, the jets under that hats are the pilot air and main air jets, but I forget exactly what circuits the air jets in the back connect to.

You can tell their hitachis by the little bullseye symbol on the float bowls. That's the hitachi symbol. Here's a cool explanation on the meaning: http://www.hitachi-automotive.us/html/about/index.html

 

Thanks guys I think,now I'm getting nervous so overall they look past it and I should by her a rack job so too speak if so there went the budget build lmao

 

in the pic if this is what we are all on about its just been blocked off by a bloody mud wasp lil bastards get into everything

 

Thats funny, last weekend I pulled out my '85 XJ700X carbs too:









Even more images: http://imgur.com/a/lqdlM

 

Ok gurus do I pull this rack totally apart and do these carbies individual. or do I leave them assembled on the rack and pull them apart your input is greatly appreciated cheers

 

Take the rack apart. Get new throttle shaft seals and o-rings for the fuel tubes that go between the carbs.
Looks like you put that whole rack in the carb soak. Are the floats OK? That stuff is alittle hard on composite floats.
In any case take lots of pictures and just do one carb at a time.
XJ4ever has kits now that have all the parts and screws you will need, including float bowl drain screws.

 

beerhound.. yes, break th rack and put it back together much better than it was b4, they're a very important part of th beast.

 

In the last picture , what up with slots cut into the towers where the pilot screws go?

MN

 

:? :? :? :? who's pics mine or RvdH

 

RvdH's carbs? Look like the towers are cut?

Maybe the pilot screws are stuck or something.

MN

 

OK 35 minutes just too remove these bloody screws without stripping the heads too pieces





Well not taking this long so out came a good friend



The back rail seen what happened too the front hehe



Diaphram hmm wouldn't want that assisting any part of my body lol





After all this came too the grand conclusion SCA CARBY SOAK is C R A P

More pics to follow stay tuned it gets better lol

 

Yes, it turns out the previous owner (or the one before him) cut into the towers to be able to unscrew the pilot screws. They do seem to be unstuck now.
