VAGA hammering at low rpm

Can anyone tell me, when goldwing working at 1500 rpm and a little less, really hammering can be heard in the engine, and when you raise over two thousand, it starts to work fine, while driving works great, but because impossible while standing in place, unequal work and will go off as soon as you try to put a thousand revolutions, I bought a liquid that is poured into gasoline, to clean the carburetor, valves. consumption of gasoline per 100 km to 6.5 liters, as very few know about goldwings and maintenance and anything else related to the engine, I hope that I can rely on you

When was the last time his carbs were synchronized?
If his carbs are off by a fair margin, they can/will produce a 'hammering' sound from just off idle and then quieten down over 2,500 RPM, or so.

Try to give more info as to sync to carbs or any other info you might give.

I believe this is his first goldwing and is trying to learn a lot in a short period of time.

He just got the bike registered after a hassle from the gov't as they had no info on bikes older than 1988.
He is from yougoslavia and apparently no one knows anything about goldwings there.

Hopefully he will chime in here to give more info as it becomes available to him.

Cobra, if you own a 80/81 model the idle jets are pressed into the towers in the carbs, you can either remove them or you will have to boil the carbs, what you are describing is the sound of clogged idle jets, your bike should guide away with no chatter at all...I pulled mine and cleaned them up as it made noise something aweful before I did..This is risking for some people to do and many can't seem to get them out..I have never had a problem removing them.. Do a search on removing them...I just saw a good one over at the NGW site..The guy heats up the base where the jet is installed and then he used a screw to retrieve it..It makes sense to me to heat the area first from the outside, shoot then maybe a guy could shoot some compressed air straight down the center of the jet then try the screw to remove it...My way of thinking would be that the heat would expand the exterior of the case and the compressed air would reduce the expansion of the jet and it should come out much easier.. You won't hurt the jet from above with the screw, you have a good 1/2" of meat before you get to the actual jet hole in the center of the jet, note that there are holes on the sides as well...use a really small wire or guitar string to clear the way on these tiny jet holes... I soaked my jets in carb cleaner over night before trying to clean them out..Oh yeah Cobra, on the 82/83 the idle jets can be removed with a flathead screwdriver, get one that fits or grind down a screwdriver if you have to to fit into the hole to turn the top of the jet out, don't use a screwdriver that to small for the slot...They finally got smart and made these so you can get them out...I'm really pretty gosh darn sure that it's your idle jets giving you this problem these are also known as slow jets too..Have a good day sir..

Sync those carbs first. I had that same sound (a little bit like a few marbles rolling around in the engine) when I got my latest Wing. Here is the link for the how to. viewtopic.php?f=11&t=81

This fixed mine. Your symptoms sound just like mine did.
