OK get back with the year and will tell how I would proceed.

I made some small adjustments to the synchronizer screw and I could get the popping to go away but it still misses between 2000 to 2500. I guess I'll need to get some gauges to sync the carbs. Do you know where I can get the vacuum fitting for the right bank? Many will start jacking sync screws loo...

Hi guys, I have two questions that bother me: - where is reverse gear relay located? - what is that electronic box on the picturess? What for is that box, all information will be welcommed.Thanks in advance Piotr Do you mean reverse relay switch? That would be under the seat on the thin crossmember...

The 1500 ignition system is pretty much bullet-proof. Most running problems can be traced back to carb and mixture problems. Remove air box cover and air filter. With a can of carb clean crotched road test bike to the offending RPM and hold there then spray the carb clean into one for a test then th...

The mixture (pilot) screws control amount of fuel entering engine.

The amount of air entering the engine is determined by where the throttle plates of the carburetor are positioned, almost closed for idle up to wide open.

To this air entering the engine fuel is metered in by way of the mixture screw, out for more and in for less.

Generally a good article but the author is in error about current leakage of 20 milliamps. Factory spec for current draw is not to exceed 5mA.

I'll try and add a picture once I get all the damage exposed. So far I just see four wires melted but I haven't been able to get it much more of the harness cuz it goes behind the frame. You found the source of the short which is good. Now you have to determine the why as to not get a repeat after ...

I just wanted to post a note here... I am sick and tired of AGM batteries and I bought my last one 07 August 18. I know this because that is the date I wrote on it six months ago when I bought it. I have been through about 4 or 5 AGM batteries over the last few years. They die. Well, all batteries ...

Thanks for your input CT1500 but I was able to unplug those three Junctions and it still has a short but at least we've eliminated those three. Could it be right in the ignition switch seeing's as soon as it goes from accessory to ignition the fuse blows? Nope, power feed is battery, ign switch, fu...

There are two red connectors above fan, you sure the right one got disconnected by confirming wire colors? If fuse #11 15A only blows with relay 6 installed it pretty much narrows it down to Blk/Lt Grn trace wire which is main feed. With C43, 55 and 57 disconnected now undo C315 yellow connector beh...

I would bet the problem is in the right handlebar multi-function switch for kill switch. Disconnect C57 above the right fan or just open the switch looking for the short if you can understand electrical circuits, doing so will start to narrow down the problem. C55 and C43 will also be involved if C5...

Reverse module is on the left side of bike from operators perspective.

Question if the ecu is up on the right side of the tank what are the 2 black boxes on top of rear wheel internal fender?

The reverse and cruise control modules.

I am going to replace the plugs and go from there. Years and not miles probably getting to the plugs. Was riding yesterday and twice the engine hiccuped one time while cruising at speed, Kinda gets your attention when this happens Spark plugs will either work or they don't with some varying degrees...

Plugs were changed about five years/ 40 k miles ago and wires probably never. I have read on some forums that wires are never an issue but mine could be different https://goldwingdocs.com/forum/viewtopic.php?t=38533 You however are reporting a problem unlike the thread linked.

When were the spark plugs last changed? Seriously, old possibly fouled and widened gap spark plugs can require more voltage to fire and lead to the breakdown of now 30 yr. old plug wires.

If it were my ride plugs and wires would be on the to do list.

The 1000 after 22 years would need more work than it is worth. :( The 1500 is one of the most complex and difficult to work on/diagnose motorcycles ever made. As the Ern mentioned earlier plastic can hide a multitude of problems and you do not know what lies beneath until removed. One must be famili...

We hear advice and read about replacing spark plugs in so many threads regarding poor running engines, high speed misfiring, low speed hesitation, left bank not firing, #3 cylinder not firing and the list goes on..........Well I wonder how many times spark plugs have been purchased and installed fo...

I was tipped off by Bellboy to this thread and would love to go through this machine, thanks Bellboy. Unfortunately winter is here with snow and below average temps working in the garage I cannot do. I PM'ed this to the author in Israel. Colchester is 15 minutes away

Thanks

Without a visual on the MC to see what has been done/condition it is and not knowing the history of repairs or added devices. It sounds like you have something mis-wired or a low grade/intermittent short/path to ground or faulty supply/relay voltage. You need to identify the particular circuit invol...

The confusion may stem from the fact that within the idle fuel circuit a tiny amount of air is mixed in via an air bleed so there is a mixture of both that the needle of screw acts upon.

All those vacuum hoses attached around the upper perimeter of the carbs are air bleeds for the circuits (idle&main) within the carburetor to meet emission requirements of the day. They will lean out mixtures via the air jet controllers. There is also an altitude compensation system among those hoses...

Yes the fuel mixture screw meters fuel just like every other carburetor ever made, out for more (richen) and in for less.

The 1500 fuel pump dies a slow death with symptoms of reduced fuel pressure. Easiest way to confirm this intermittent problem which only happens at road speeds is to tee a fuel pressure gauge into the fuel line and tape to the shelter where it can be seen. This will allow you to monitor the fuel pre...
