    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

alright so heres where im at...

#1: so as i said before the number 1 carb had a cracked post...whoever broke it tried to patch it up and it seemed to be alright...well as soon as i pulled the pin out it fell apart...could i just buy a blank carb body....so what are my options?

#2: all the air screws in all 4 carbs are all seized up...i got 2 of them about a half turn out then the screw heads popped so that was that...could i just drill them out and buy new ones...what are my options here?

You can try to post a ad in the wanted section of this board for the carb body. Bet someone has one or you can do a search on here and try to repair it. Its been done..
As for the screws, if you're talknig about the mix screws you may have to try to drill em and tap em but I have no experience in that area. Never had to do it.
Someone will chim in just be patient.
 
well it looks like drillin em out is out of the question...those things are solid...i realy would hate to have to replace all the carbs just because of air screws...any suggestions

They're brass dude. I little drill bit and easy out should do the trick.
Did you hit em with some thread breaker?

Chef, where are you??
 
yea i coated em with pb blaster...im no metal expert but im not so sure they are brass...they are silver in color

as far as the float post goes i am taking it to these guys tomorrow to be welded back http://elitefab.com/

i also got 4 rebuild kits on order for these carbs so if i can get the air screws out ill have brand new ones to put in

You can use a Dremel and a fine cutting wheel, slice down through the raised portion of the carb body that shields the screws and cut a fine notch in what is left of the screw. Then using a straight blade screw driver, give them another shot. :o Has been done several times, though, not by me.

i guess thats an option...not sure how i feel about hackin up my carb tho...have you ever used those backout bits they use to backout rounded out screwes...wonder how that would work
 
Yes, I have. They work great IF you can get the bit to go far enough down. A little rap with a small hammer and 'usually' things pop loose.
 
alright after breakin off a stripped screw remover inside the head of one of the air screws i was trying to get out i decided to just take a dremel to it and gring a deep slot in the head as suggested earlier...couldn't have been easier...wish i would have done that sooner...now all i gotta do is get that post welded...my rebuild kits are coming in on monday along with some other chrome goodies so hopefully ill have her up and running again

Re-do the carbs accorcing to Basscliffs page. Do em PERFECT! Make no shortcuts. The VM carbs are very thouchy and have tp be perfect.
Replace all rubber orings in the carbs.

Replace intake orings with new provided by http://cycleorings.com/
Put the airbox on making real sure its sealed with a good clean filter.
Put new plugs in. Ya might as well buy at least 8 plugs while you're at the parts store.(NGK B8ES)
Leave the petcock on prime.
Start the bike....

Do all this and report back with your results.

I agree... But his bike doesnt have VM carbs.. it has BS (CV type) carbs just like your 850.. either way, they need to be completely torn down and dipped and cleaned and ALL of the orings replaced. Get a set from the above vendor. Shortcuts will lead to continued frustration. Its not hard, especially if you just do it right the first time.
 
+1 for following the basscliff/GSResources carb guide. and make sure you have a good seal for your airboxes too (I'm in the process of resolving that one :D my idle is horribly inconsistent - but my bike does run and gets 45mpg!)

The first carb teardown is the hardest. After that, it's a walk through the park. Good luck! :)
 
Its alive!!!!!!!

Its alive!!!!!!!

so i finally got her up and running today...what a long hard battle it has been with the carbs...it was all worth it...as far as i am concerned after sittin for a few years she sounds pretty darn good...im sure it needs some sort of adjustment tho.

all the noise you hear in this from when the bike starts is from the bike itself...there are a couple clunking noises in there that made me nervous
