carb help

Postby tyrevere » Fri Sep 04, 2015 12:57 pm



i have found a vacuum leak coming from the piston vacuum on the left side of the carburetor.

As I can see the only way to get to it is to take the carb off since the cap is right against the frame.

how does the carb come off? is it the 3 screws on the top that you see when you take the air cleaner off?

There is no how to article on 1500 carb removal. The best I've found on goldwingdocs is virgilmobile's post here and there's this one. I got my bike down to airbox off today for a carb pull. I might take some pics tomorrow and try a how-to seeing as the internet is kind of short on them.

so yesterday I decided I would try to pull the carbs off, I got as far as removing the top plate that holds the linkage but for some reason I couldn't get the linkage off of it... after getting frustrated I put it back together without taking the carbs off or fuel lines etc. I decided to take it for a spin and, dam the thing ran better then it has for the past few years I had it. it felt new I was like what the hell is going on.. the acceleration was perfect, there was no dead spot or anything it was very smooth.... THEN 2 hrs into the ride the hesitation came back but not as bad but it was there... I don't know whats wrong but I guess ill find out, unfortunately I have to have the dealer do the carb work since I cant get them off...ugh more money

Nowhere in those links I gave you did it say to try to remove the top plate while the carbs are still on the bike. The choke rod linkage is underneath held on with really small cotter pins. Also, the top plate is one of the main things holding the carbs together as an assembly. If, for some reason, you were able to remove it while on the bike, then went to rocking and prying on the carbs, odds are you'd have bent or broken the throttle linkage, accelerator pump or the coolant plate. In my opinion, a carb overhaul on the 1500 isn't nearly as much work as a 4 cyl wing and is easily doable if you are mechanically inclined, Read through this a couple of times then decide if you think you can handle it before giving a stealership any money.

I did not rock pull or anything, I try my best to avoid that so I don't bend anything...

Oh, but you will have to rock, pull and pry to get 'em off ;) Like I said, read those pages I linked thoroughly and decide if you want to tackle it yourself to save some bucks. If so, I suggest taking lots of pictures to help with reassembly and post back here with any questions.

Mine were stripped and cleaned on Monday this week, not by me though.

I was at my mechanics and watched him do the whole lot - giving assistance when required.

The hardest part in my opinion is the multitude of vacuum hoses - which you have to be quite dextrous to remove - - undoing the carbs from the mounting plate once removed from the bike is relatively simple in itself.

There was no great grunting and pulling, pushing or prodding the carbs to get them off - maybe he was lucky - or just good at his job.

Have a read of this it might help a bit

viewtopic.php?f=6&t=29959

The vacuum top also has 4 screws to remove - not three - if you don't want to take the vacuum tops off - you could remove the set plate which will give access to the slides - I would see if the slides both move up and down and spring back easily - if one of them is hung up it could be causing your problem. Give the carbs good spray down with carb cleaner into the slides area if one is sticking - it could clean it up enough to make it work properly.

cheers

And I ride all year long, as long as the roads are there. :twisted: It must be getting close to that time when you Northerners have to plan your maintenance so that you can maximise your road time, when there is no snow, no ice, no salt, no grit, and no whinging how cold it is :lol:

I never complain about the cold...so lumping me with "northerers" is little judgmental

We're almost all Northerners here compared to Redial.

I get a load sucking noise on the left side of the carb and a terrible "dead spot" with at all speeds hesitation. and my clothes would smell of gas when I got done with a ride.
before I tried to take the carbs off ( couldn't get them off) I had it all the time but now its a lot better but still there.... it runs very smooth now like its brand new for about 2 or 3 hrs. then it acts up again. so im not really sure if its a vacuum problem if it is not all the time now.

I know its the left side because when I had the air filter assembly off I covered the left side with my hand and the sucking noise was muted.
