Hello everyone,
New guy here. Just picked up an old GS from my boss. 1990-91. He had rebuilt it from the ground up but never had it quite running right. After some help from one of my mechanic buddies we determined the root must lie in the carbs. So, by his advice I stripped them down. So far everything looks decent, however I did notice an issue. On both carbs, the white plastic piece inside, the slide guide I guess it's called, is busted. Not completely, but the ring on the bottom that the emulsion tube sits in is broken off and comes out with the tube. I could glue it back in place since it is there...but that seems, not right. Also, the tabs on the top are pretty well beat up or missing.
The question is, I can't see this anywhere as a "replaceable" item to buy. Any ideas?
Side question, the intake mounting flanges for both carbs are showing some age, in cracks on the outside, but I took them off and from the inside they look really good. Does the outside really matter too much?
Thanks in advance for your help.
Are you saying the metal is cracked?? Or are you talking about the little rubber boots?
If the inside is okay looking then I guess it's okay but I would want to know why the metal is cracked if it is.
Sorry, I don't know that that plastic bit can be replaced. You could maybe get in contact with Mikuni.
I would hesitate to glue anything - you might ruin your carbs.
Figured a few pics would help clarify

Yeah, you can forget that shiz man.
I suppose you could try something like Permatex that says it will resist gasoline...otherwise, whatever you put in there is just going to melt when exposed to gas...and ruin your carbs.
I would contact Mikuni.

Or you can just find replacement carbs from a board member or eBay. There are plenty out there.

Replacing the piece might be cheaper, that's why I suggested it. Used carbs ain't cheap!
But that is also a good idea...maybe someone on here has new ones for you...
I'm going to check here, I've exhausted ebay. It's hard to justify a whole new set of carbs at the moment.
try the local stealer or the on-line fiche places.
There is no way I'd run that, and I pull a lot of crap that people say don't do.
Those are busted from somebody not understanding how to remove them, or trying to get them out without pulling the jets first. Funny they did it to both though :dunno_white:
If you knew the bike didn;t run 100% before you got it, you already knew you would have to invest a little into it.....Good Luck.
meh - I see it's not on the parts fiche. Still might be worth checking the dealer. I guess if I really couldn;t find it...... I would try to glue it before I'd park the bike......
Yea $20 shipped for a pair of white guides ... pay up .... muhahahahah ... seriously I have em liberated from carbs ... so yes $20 shipped in US.
You need a set of those seating O rings in that too, I'll send one of those along too.
Cool.
Buddha.
Do you have a source to find those seating o-rings new Buddah? I would like to get another set to make sure that mine don't cause issues considering they don't look in the best of shape.
I sent you a PM Buddha. You are saving me thanks.
I knew I would have to put some work into this baby. But it will be worth it. After all my boss did with it, a few parts here and there are not a big deal.
