GL1500 carb question

puum said:

I have my carbs off. On that rubber piece that goes between the carbs and intake I can wiggle it back and forth a tiny bit even though the bottom clamp is as tight as I can get it. Both sides are the same. Is that normal or a problem?

Thanks.

Yes, and yes.

There is a spacer that lets the clamp be tightened just so much. You can install new boots, or file the spacer.

BTW: The upper clamps are the similar and might have play unless you do the same with them.

If your talking about the molded rubber piece, thats clamps to the carb thats on the turn downe tube that bolts to the head? Yes a possible vacume leek!

The upper and lower clamps are sized differently.

An occasional rocket scientist will come along and mix them up. Check that they are indeed where they belong.

....I suppose the right thing to do is to order 4 new clamps and 2 new insulators and just replace everything?

What the heck does that mean? I'm not blind and I read every reply multiple times.

If you're referring to your reply, you told me I could file the spacers or replace the boots. To me, filing the spacers doesn't seem the "right" thing to do. I would think Mother Honda made them the size they were for a reason. :? Maybe in the short term, but if there's play and there shouldn't be, then something isn't right and a new set should take care of everything. And in the long term that would be a better solution. Maybe the rubber is old and stiffer than it should be. I don't know.

Also someone mentioned that the clamps were different sizes. My own deduction is the only way to know for sure that the correct clamps are on the right end are to order new ones and match up the part numbers.

If that's not what you're talking about then enlighten me. I have no idea what you're talking about.

I ordered new carb insulators. I put them on and those babies are tight now. No wiggle at all.

Incidentally, the two clamps sure look the same size to me, and I don't see how anyone would be able to put them on wrong. The bottom clamp on the left carb is the same as the top clamp on the right carb, and vice versa. That would indicate they are the same size.

The only difference is that each have two "fangs" sticking up, which are used to hold them from spinning on the carb insulator. I don't see how it would be possible to put them on wrong.

Now, if those little carb insulators would fix my fuel mileage I'd be one happy camper. I also replaced a bunch of vacuum lines that I would call "suspicious," although I couldn't find any obvious holes or cracks in any of them.
