I've had a 'look' at my vaccuum hoses and they seem to be ok, however, that is only the ones that I can see. As everyone, here, knows they go all over the place and you can't check them all until you pull the bike apart. I will add it to my list. I realise this is going to take some time.
You are right about the supply of parts. The Gold Wing is not the most common bike over here and the parts supply is not good and very expensive. I tend to buy from the US over the Internet but that can take a bit of time.
The cost of fuel here is NZ$1.52 = CAN$1.21 = US$1.03.
So that actually compares pretty well with your prices. We thought we were hard done by because the prices have skyrocketed. Guess it is happening everywhere.
Al, formulating a list is great way to work your way through your problem.. I'm not sure why Vic thinks you are "running around like a chicken with his head cut off" butthat is his opinion not mine. It sounds like you have a good planof action & you are asking plenty of questions so should have a good idea where to look & what to check.
Can you think back to when the problem started? Was anything added or changed around that time? No chance you added a free flowing air filter or something similar?
Is this only a 3000 RPM acceleration problem? Or do you get in in all gears at different RPM roll on's?
Here's something to check into,, the 1200 Wing uses an input to the ign box to allow 4th & 5th gears to use a vacuum signal to control spark instead of a fixed spark curve.. I can't tell you if the 1500 uses the same type system or not.. Maybe someone with a 1500 manual or that has researched the 1500 spark control can shed some light here. IF, your bike has such a system & theign system doesn't see a 4th or 5th gear signal you wouldn't get much spark retard on acceleration in the top gears. (kind of just tossing this out here as I have no idea if the 1500 has such a system or not)..

Twisty, since you questionedthe statement I made about running around like a chicken with its head cut off, I just want you to know that itdoes not solely apply to you. I manage, moderate and am Senior Guru at several Gold Wing sites and in my experience I see a lot of misdirection on the parts of well meaning people who genuinely like to help or simply seek to outdo others with the knowledge they think is correct. All of their input is greatly appreciated but not always accurate. In fact I even screw up occasionally, but, I'm not ever afraid to acknowledge and correct my mistakes so that others will have the appropriate facts available to them.
Steve Saunders and I are slowly working towards creating a special section on this site that will contain only 99.9% accurate information regarding Gold Wing specs and maintenance, but, until that comes to fruition I'llneed to make corrections here.
Now don't get offended and please remember that it was me who recomended you for Guru title herebut, this line of your post is the type of misleadingthing that I'm speaking of;
Twisty said: "IF, your bike has such a system & theign system doesn't see a 4th or 5th gear signal you wouldn't get much spark retard on acceleration in the top gears.
Yourstatement is not accurate and could create a lot of confusion for a guy working on his Wing for the first time. Your statement could really mislead someone and cause them to spend hours of diagnostic time for no reason and may even persuade them to replace parts that don't need to be replaced.
Maybe you're just exhausted after a hard day and posted the wrong facts, but, still the facts you posted might be believed by some unsuspecting newbie who trusts your Guru title and writing style. To me, that gives this site a bad name because the information proves to be unreliable and I try to work real hard at keepingmaintenance and repair facts accurateon this site.
Perhaps what you meant to state is that the Gold Wing vacuum advance system advances (it does not retard)the ignition timing 11.5 degrees when the gear shift switch is closedin 4th or 5th gear and there is at least 1.2 -2.0 inches of intake manifold vacuum. The internal electronic advancecurve begins at 1500 RPM and gives atotal 33.5 degrees of advance at 3200 RPM. From these facts and using a timing light one could accurately check the ignition timing advance system accurately and be secure in the knowledge that the system is performing correctly as designed. Using your instructions a guy could be running around like a chicken with his head cut off trying to figure why his bike doesn't work right.
Keep up the good work here Twisty, but let's try to get it right as much as possible so we don't have people sayingthey got the wrong info from that so and so Steve Saunders site.
