T...take the basket out of the can and you can do 2 side by side. Cuts the total DAYS down a few. And I use bread ties thru the holes in the jets and pilots and wire them to one of the bodies during the first round, and the float seats and other stuff to one during the second batch.

Everything is dipped and done in two days. Screws I just use the wire wheel on the bench grinder and polish them up. Brackets and other hardware get wire wheeled also.

I don't disagree with your theory but the directions on my new Berryman's can says a normal dip is 15-20 minutes with a 1/2 hour max. Otherwise it warns of damage to the finish.

I hate the look of those carbs that were soaked for too long -- they look dull and spongy. :lol:

For the visible crap, the 30 minutes didn't do the trick -- but the hour and a half with agitation sure did. Hopefully, the stuff I couldn't see met the same fate.

My carbs are in pretty good shape for being 32 years years old -- right now, they look nearly brand new.

I guess I won't know for sure until it's up and running.

:pray:

I do the full 24 as was directed by members here when I got started....because they had been there, done that, and KNEW BETTER!!!

They also knew that 30 year old carbs didnt have any "finish" left on them to be worried about. The 24 hrs hasnt made any carbs dark grey and stained them all ugly...thats all simple urban myths.

And when it's not, it's going to be a real pain in the a$$ to pull them out and do it all over again...

But I do wish you luck, and hope it goes well on the first try...

I never soak carbs longer than over night. Guess if your dip is old though it may take longer.

Stuck slides can often be removed after heating the carb body. Varnish forms between the carb body and the slide and heat breaks it down.

My 32 year old carbs definitely have their original finish. And it's not just the outside finish that I worry about having seen what ethanol can do to the inside of some carbs.

And yeah, it's no myth, I over-soaked my dirt bike carb a few years ago and destroyed the finish. They look like **** but I don't mind because it's a dirt bike -- my GS is mint, I'd mind.

And since I destroyed the finish, the dirt bike carb seems to collect debris a lot quicker and needs to be cleaned more often.

I am under the impression that those directions were written back when the chemical formula actually worked within that time frame. When they changed to a more "environmentally-friendly" formula, nobody bothered to update the directions.

It is not just a few of us here that HIGHLY recommend ignoring the directions or at least changing one word in them. Instead of reading "15-30 minutes" (as shown on my cans), it should read "15-30 HOURS".

Bottom line: do it for as little time as you want, but if you find that the carbs are still not working as they should, ...

He will find out his own way Steve. all I can do is share to try and save the grief. Like i said..been there and done that.
 
I've seen carb bodies turn dark when left in the dip too long, but never seen one turn all scaly like that photo shows. Something odd there. What brand of dip was used?

None.

That was a carb bowl that came off of my buddies lawn mower -- my guess is that it was the ethanol -- but something made that finish peel off like that.

My only point is -- it does happen.

:)
 
If it did, something else caused it. I've left carb bodies in the dip longer than 24 hours and never saw anything like what you are saying.
 
We're kinda beating a dead horse here.

There are tons of variables involved but the point is, a carburetor's finish can be compromised and one way of doing that is by leaving them in dip for too long.

My '81 GS has never even seen a drop of rain and is in mint condition - not very much different from the day I rode it out of the dealer's parking lot 32 years ago. I'm not willing to take the chance of destroying the finish on my carbs by over dipping them.

If they don't work the first time, I'm perfectly willing to do them again and again until they are clean, if that's what it takes.

I'm pretty confident that they're going to work just fine -- this isn't my first rodeo. I'll be sure to report back and let you know.

So you post 2 pictures, one of a carb and one of a carb bowl of which neither was in Berryman's dip....

So I don't get the point.

Your GS is mint, never seen rain, and so on.....so what is the point of dipping the carbs ?

If you think they are gunked up on the inside, get some gas line antifreeze one of those small bottles pour it into a tank of gas and run the bike for a bit, the gas line antifreeze will eat away at the gas that has shellacked (sp) and you should be good to go...an old way we used to clean up the snowmobile carbs after letting them sit for the summer.....

Run them thru 2 or 3 cycles in an ultra sonic cleaner then..but the finish still is gonna be in some kind of cleaning solution...so its a crap shoot either way for you I guess.

Boiled a carb in lemon juice (diluted of course) and it turned dark. Never again. Gunk or Berrymans's carb dip is much safer in my experience.

I agree with minimizing the dip time to minimum required. Throttle shaft seals are rubber and don't need any more exposure than necessary.

Mr. OriginalOwner, feel free to check the carb rebuild tutorial linked in my signature. Even though you have some experience with old bikes, it won't hurt to learn some specifics about the GS Mikuni's.

Good luck
